Safety Instructions
i
Intended use:
The SLS-Cis designed for operating in a drive system.
- An installation is allowed only, if the requirements of the EC Machinery
and EMC Directives are conformed with.
WARNING –Serious injury from electric shock!
If the SLS-C is not operated with SELV/PELV voltages, the risk of dangerous
voltages may be on the device. Touching these components carrying high
voltages can cause serious injury or death from electric shock:
- Always observe the safety concept SELV / PELV to ensure safe isolation
and separation of low voltage supplies from the mains.
WARNING –Serious injury from electric shock!
During electrical installation cables, connectors, etc. can be live.
- Before starting wiring, make sure that none of the power supplies is
connected to the primary side of the mains supply. Isolate the power
supplies from the mains or remove the appropriate fuses.
- All modules must be inserted and screwed into the SLS-C housing
before powering up. If necessary, unoccupied module slots must be
covered with the supplied blank front plates.
Never operate the equipment when open.
- Do not plug or unplug the modules while powered.
- Do not plug or unplug the connectors while powered.
- If the equipment was energised, wait 3 minutes after power off to allow
the capacitors to discharge and ensure that there are no residual
charges on cables, connectors and boards.

5 Mounting Information
i
Mounting
Observe the following when mounting the SLS-C.
- Unpack the SLS-C unit carefully.
- Avoid strong collisions and fitting.
- Attention: The SLS-C weighs up to 30 kg (66 lb).
- Pay attention to the manufacturer’s instructions of the cabinet before
mounting.
- Mounting rails must be fitted to the 19” device.
- Insert the SLS-C from the front into the rack and screw it on the left and
right side of the designated holes with the rack.
- Tighten the screws well.
- Don’t cover all ventilation slots.
- ‚Blind front panels must be mounted before putting into service.
The SLS-C must be closed on the front side.
- Consider the cabling design requirements! See chapter: Cabling design
requirements.
- Observe that the bending radii of the cables are sufficient during
mounting. Never stretch the cables or break them. The existing ground
clamps support the correct cable laying, but not the strain relief.
- Observe that all connectors (for motor, control pulses, mains,) are
connected or fitted properly. An interchange of the axes can be avoided
by marking the mating connectors.

6 Protective Measure for Power Supply Units
with Power Stages up to 70 VDC
SLS-C with power stages up to 70 VDC must be operated by the protective measure
PELV acc. to VDE 0100. The unit and motor housing have to be grounded. The ‘0 V’ in the
unit is grounded. Motors with grounded conductor clamp have to be connected to PE.
The protective measure PELV is fulfilled, as follows:
i
CAUTION –Possible damages!
To avoid damage to property, please consider the following points in your safety
concept:
- Protective measure PELV for application of the +UB should not exceed 70
VDC or 50 VAC at dry environment (environmental conditions 3 acc. to IEC
61201).
- The supply transformer must be constructed with reinforced or double
insulation between supply and secondary winding (acc. to EN 61558).
- Only use motors which are checked acc. to EN 60034-1.

SLS-C Manual
MA 1317-A001 EN 14
7 Protective Measure for Power Supply Units
with Power Stages up to 120 VDC
The power supply SLS-C units with power stages over 70 VDC must be operated according
to VDE 0100 part 200 with protection by automatic disconnection. Therefore, the motor,
power stage, `0 V` and each equipment have to be grounded:
i
CAUTION –Possible damages!
To avoid damage to property, please consider the following points in your safety
concept:
- When protection by automatic disconnection (EN 61140, VDE 0100, part
410) is used for power stages with definite voltage > 50 VAC or +UB > 70
VDC:
- Only use motors, which are checked according to EN 60034-1 (500 VAC
+ twice determined voltage.
- The motors must have a protective conductor clamp (EN 60034).

8 Cabling Design Requirements
Which devices?
SLS-C power supply units with built-in power stages type MSX+and
ZMX+.
Which cables?
Mains, I/O, logic control and motor cables
What is to be
observed?
The secondary motor circuits (motor current circuit, I/O and logic
circuit) are not insulated by means of a protective separation as
defined by the EN 50178 European Standard.
Therefore the connecting cables to all secondary circuits (I/O cables,
logic control cables and motor cables) should have a basic insulation
appropriate to the maximum voltage which might be met during
normal operation.
Depending on the special requirements of the application and the
insulation concept for the complete machine, it might be necessary to
apply a reinforced or double insulation for this voltage. In some cases
it could be necessary to mount a protective earth connection at
adjoining metal parts which might be accessible for persons.
The cable insulation design voltage should be at least as given in the
following table:
Power stage with
nominal voltage
up to 70 VDC
from 70 to 90 VDC
from 90 to 140 VDC
Rated voltage

We recommend using a shielded cable, as short as possible (< 1 m).

9 EMC Requirements
CAUTION –Possible damages!
Please consider the following references for EMC reliability:
- Only use shielded cables.
- The cables should not be interrupted by additional connectors or
screw terminals from the unit to the motor in order not to deteriorate the
shield effect.
- It is important to connect the shielding mesh to the motor housing on a large
area. Use special EMC-type conduit fittings. All parts of the motor should be
conductively connected with each other. We recommend using EMC conduit
fittings at the motor side.
- In case of motors without adapted conduit fittings the cable shielding must
be connected as near to the motor as possible and has to be applied to the
housing.
