Electrical installation
DANGER
•
The mains and DC-link terminals may hold dangerous voltage levels even after disconnection
from power supply. Wait for 3 minutes until the DC link capacitors have discharged before
starting to work at the unit.
•
The unit may only be connected with the power supply switched off.
•
Verify safe isolation from power supply.
Do not carry out high voltage insulation tests on cable connect to the mains unit.
Use copper leads for ≥ 30°C environment condition.
Connect mains supply.

EMC information
The mains unit is designed according to the requirements and limit values of product norm EN 61800-3 with an
interference immunity factor (EMI) for operation in industrial applications. Electromagnetic interference is to be
avoided by expert installation and observation of the specific product information.
Measures
Install the mains unit and its components (radio interference filter, line choke, sine filter) on a metal mounting
plate, ensuring full-surface contact with the plate. Ideally, the mounting plate should be galvanized, not painted.
Provide proper equipotential bonding within the system or plant. Plant components such as control cabinets,
control panels, machine frames, etc. must be connected by means of PE cables.
The shield of the control cables is to be connected to ground potential properly, i.e. with good conductivity, on
both sides (shield clamp). Mount shield clamps for cable shields close to the unit.
Connect the mains unit and its components to an earthing point via short cables.
Excessive cable length and loosely suspended cabling must be avoided.
Contactors, relays and solenoid valves in the control cabinet must be provided with suitable interference
suppression components.

Connect to a common direct voltage source. Cable with a length >300 mm
must be shielded, the cable shield must be connected to the mounting plate
on both sides. Use twisted cables where possible.
Control connection (X210A, X210B)
C
Control and signal cables must be kept physically separate from the power
cables. Analog signal cables are to be connected to the shield potential on
one side.

D
Mains cable to be installed separate from control and signal cables as well as
DC link connection.
Install radio interference filters at the mains input of line chokes. As from a
length of 300 mm the cables installed between radio interference filters, line
choke, sine filter and the mains unit must be shielded. The shield is to be
D
connected to a PE bar properly using a suitable cable clamp (large contact
surface).
If a brake resistor is used, the connection cable must be shielded, and the
cable shield is to be connected to earth potential on both sides.
