Electrical installation
· Cable type
Use shielded mains, motor and signal cables with double copper braiding, providing
60 to 70 % coverage.
· Cable laying
– Lay mains, motor and signal cables isolated from each other. Maintain a minimum
clearance of 0.2 metres wherever possible. They should not run in parallel. If crosso-
vers are unavoidable, they should wherever possible be congured perpendicular (at
a 90° angle).
– Always route the motor cable without interruptions and by the shortest route out of
the switch cabinet. If a motor contactor is used, for example, the component should
be directly mounted to the drive controller and the shield of the motor cable should
not be stripped too soon.
– As far as possible route signal cables into the switch cabinet from one side only.
– Cables of the same circuit must be twisted.
– Avoid unnecessary cable lengths and loops.
· Grounding measures
The grounding measures of relevance to the drive controller are detailed in section
3.5 “Protective conductor connection”.
· Shielding
Do not strip the cable shields too soon, and lay them across wide areas both on the
component and on the backing plate and PE rail (main ground) of the backing plate.
· External components
– Place larger consumers near the supply.
– Contactors, relays, solenoid valves (switched inductors) must be wired with fuses.
The wiring must be directly connected to the respective coil.
– Switched inductors should be at least 0.2 metres away from process controlled
assemblies.
Supplementary information can also be found in the relevant connection description.

3.1 Notes for installation
ATTENTION!
• Qualied personnel
Installation must only be carried out by qualied electricians who have under-
gone instruction in the necessary accident prevention measures.
• During installation,
be sure to avoid ...
- screws, cable residues or other foreign bodies dropping into the device;
- penetration of damp into the device.
DANGER CAUSED BY HIGH VOLTAGE!
• Danger to life!
- Never wire or disconnect electrical connections while they are live! Discon-
nect the device from the mains supply (230/400 V AC) before working on it.
Dangerously high voltages of ≥ 50 V may still be present 10 minutes after the
power is cut (capacitor charge). Work on the device only once the DC link
voltage has fallen below 50 V residual voltage (indicated by monitoring LED H1
and measured at terminals X1/L- and L+).
- Even if the device does not emit any visual or audible signals or show other
indications, dangerous voltage may be connected to the device (such as with
mains voltage to terminal X3 switched on and no control supply on X2)!
Installation of drive controllers is subject to the following basic rules:
· Compliance with EMC product standard
Compliance with EMC product standard Commissioning (i.e. starting intended
operation) is only permitted when strictly complying with EMC product standard
EN61800-3:2004. The installer/operator of a machine and/or item of plant must pro-
vide proof of compliance with the protection targets stipulated in the standard.
