WARNING

Electric shock due to connection of an unsuitable power supply

When equipment is connected to an unsuitable power supply and/or insufficiently grounded or

rear cover (Page 19), exposed components may carry a hazardous voltage that might result

in serious injury or death.

● Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV

(Protective Extra Low Voltage) output voltages acc. to UL 61010 for all connections and

terminals of the electronics modules.

WARNING

Inadequately fused supply cables can be life-threatening

In the case of supply lines >30 m, protectors must be installed at the device input to protect

against lightning (surge).

The DC power supply must be connected to the ground/shield of the NC for EMC and/or

functional reasons. For EMC reasons, this connection should only be made at one point. As

a rule, the connection is provided as standard in the S7-300 I/Os. In exceptional

circumstances when this is not the case, the ground connection should be made on the

grounding rail of the NC cabinet (also refer to /EMC/EMC Installation Guide.)

Grounding concept

Components

The SINUMERIK 840D sl system consists of a number of individual components which have

been designed so that the system complies with the appropriate EMC and safety standards.

The individual system components are:

● Numerical Control Unit (NCU)

● Machine Control Panel (MCP), Machine Pushbutton Panel (MPP)

● Keyboard

● Operator panels (operator panel front + TCU/PCU)

● Distributor box and handheld unit

● S7-300 I/O with IM 153 interface module

Grounding measures

The individual modules are attached to a metal cabinet panel. Insulating paints on the mounting

points (e.g. tension jacks) must be removed.

It is permissible to cluster the operator control components regarding connection/potential

bonding.

Example: The control panel on the swivel arm.

It is sufficient in this instance to connect the ground connections of, for example, the PCU, TCU,

and operator panel front using a cable and to route a shared grounding conductor to the central

ground connection in the control cabinet.

EMC Design Guidelines

7.2.3

EMC compatibility

In addition to the protective grounding of system components, special precautions must be

taken to guarantee safe, trouble-free operation of the system. These measures include

shielded signal lines, special equipotential bonding connections, and isolation and shielding

measures.

Shielded signal cables

● For safe and fault-free operation of the system, the specified cables must be used.

● For digital signal transmission, the shield must have a conductive connection at both sides

of the housing.

Cable definition

Definition:

● Signal cables (example)

- Data cables (Ethernet, PROFIBUS, sensor cables, etc.)

- Digital I/Os

- Cables for safety functions (emergency stop, enabling)

● Power cables (example)

- Low-voltage supply lines (230 VAC, +24 VDC, etc.)

- Motor cables

Rules for routing cables

In order to achieve the greatest possible EMC compatibility for the complete system (control,

power unit, machine), the following EMC measures must be carefully observed:

● If necessary, signal and power cables may cross one another (if possible at an angle of 90°),

but must never be laid close or parallel to one another.

● Only use cables approved by SIEMENS for the signal lines from and to the Control Unit.

● Signal cables must not be routed close to strong external magnetic fields (e.g. motors and

transformers).

● If signal lines cannot be routed a sufficient distance away from other cables, they must be

installed in grounded cable ducts (metal).

● The operator panel fronts, MCPs, MPPs, and full keyboards must be installed in metallically

enclosed EMC-compatible housings.

Note

For further information on interference suppression measures and the connection of

shielded cables, please refer to the EMC Installation Guide.

7.2.4

EMC limit values in South Korea

The EMC limit values to be observed for Korea correspond to the limit values of the EMC

product standard for variable-speed electric drives EN 61800-3 of category C2 or the limit value

class A, Group 1 according to EN 55011. By implementing appropriate additional measures,

the limit values according to category C2 or limit value class A, Group 1, are observed. Further,

additional measures may be required, for instance, using an additional radio interference

suppression filter (EMC filter).

Means of heat dissipation

Fan design

● The fan must be positioned to produce an optimum heat dissipation. A clearance of 10 mm

must be maintained in front of the fan.

● The inlet and outlet slots must remain free for the open-circuit ventilation.

● Air filters must be provided to maintain the permitted environmental conditions.

NOTICE

Damage to the operating components caused by temperatures that are too high or too low

Contaminated air filters impair the desired heat dissipation. For handling the air filters, pay

attention to:

● Proper handling

● Regular replacement

● Correct disposal

Technical specifications

7.4 Standards and approvals

Guidelines

If the convection area A [m²] does not suffice for the "heat dissipation using natural convection",

then use:

● "Heat dissipation using natural convection and internal turbulence" for hot spots and heat

concentrations in housings subject to space constraints. The total power loss P_Ltot for

thermally critical applications can be determined as follows:

- Current measurement for a 24 V supply voltage

- Power loss P_Ltot [W] = U (24 V) * |measured value in ampères|

● Heat dissipation using open-circuit ventilation

Calculation of the volumetric flow

The power loss (thermal) dissipated by the components in an operator unit is to be dissipated

using open-circuit ventilation. The volumetric flow V required for this should be calculated at a

difference in temperature of T₂ - T₁ = ΔT ≥ 10K.

General safety instructions

WARNING

Electric shock and danger to life due to other energy sources

Touching live components can result in death or severe injury.

• Only work on electrical devices when you are qualified for this job.

• Always observe the country-specific safety rules.

Generally, the following steps apply when establishing safety:

1. Prepare for disconnection. Notify all those who will be affected by the procedure.

2. Isolate the drive system from the power supply and take measures to prevent it being

switched back on again.

3. Wait until the discharge time specified on the warning labels has elapsed.

4. Check that there is no voltage between any of the power connections, and between any of

the power connections and the protective conductor connection.

5. Check whether the existing auxiliary supply circuits are de-energized.

6. Ensure that the motors cannot move.

7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or

water. Switch the energy sources to a safe state.

8. Check that the correct drive system is completely locked.

After you have completed the work, restore the operational readiness in the inverse sequence.

WARNING

WARNING

Warning for areas subject to NEC or CEC:

Safety notice for connectors with Ethernet marking:

A Ethernet or Ethernet segment, with all its associated interconnected equipment, shall be

entirely contained within a single low-voltage power distribution and within a single building.

The Ethernet is considered to be in an "environment A" according IEEE802.3 or "environment

0" according IEC TR 62102, respectively.

Never make direct electrical connection to TNV-circuits (Telephone Network) or WAN (Wide

Area Network).

Note

When connecting an external 24 V DC power supply to the interfaces, it must meet the

requirements of a protective extra low voltage (SELV/PELV) according to UL 61010. A series fuse

must also be used, which reliably trips within 120 seconds when a short-circuit occurs at an

ambient temperature of 0 °C.

For a primary supply of the power supply used from OVC III circuits up to 600 V AC (line to neutral

voltage), it must be ensured that the contact gap of the fuse - or the individual fault-proof circuit

- is 3.0 mm according to UL 61010.

When using an external power supply, ensure that the fuse used has a trip rating that

corresponds to the maximum possible short-term short-circuit current of the power supply unit

being used.

Equipotential bonding of connection boxes

Potential differences

Differences in potential between separated plant components can lead to high equalizing

currents over the data cables, destroying the circuits. This situation may arise if the cable

shielding is terminated at both ends and grounded at different system parts.

Differences in potential can also be caused by different mains supplies.

General requirements for equipotential bonding

Differences in potential must be reduced far enough with equipotential bonding conductors to

ensure error-free operation of the relevant electronic components. The following information

must therefore be observed when installing the equipotential bonding:

• The effectiveness of equipotential bonding increases as the impedance of the equipotential

bonding conductor decreases or as its cross-section increases.

• If two plant sections are interconnected by means of shielded data cables and their shielding

is connected at both ends to the grounding/protective conductor, the impedance of the

additionally installed equipotential bonding conductor must not exceed 10% of the shielding

impedance.

• The cross-section of a selected equipotential bonding conductor must be capable of handling

the maximum equalizing current.

Equipotential bonding cables are required between two control cabinets with a minimum

conductor cross-section of 16 mm².

• Use equipotential bonding conductors made of copper or galvanized steel. Connect the

equipotential bonding conductors to the ground / protective conductor over a wide area.

Protect the equipotential bonding conductors against corrosion.

• Clamp the shielding of the data cable on the HMI device flush and near the equipotential

busbar using suitable cable clamps.

• Route the equipotential bonding conductor and data cables in parallel with minimum

clearance between them.

Note

Cable shielding is not suitable for equipotential bonding. Always use the prescribed

equipotential bonding conductors. When installing PROFINET networks, always use cables

with a sufficient cross-section. Otherwise, there is a risk that interface components will be

damaged or destroyed.

Connection graphic

The figure below shows how to connect the equipotential bonding of the connection boxes to

the equipotential busbars.
