4.1 Notes for installation
DANGER
Risk of injury due to electrical power!
•
Carelessness will result in serious injuries or death.
Never wire or disconnect electrical connections while these are live! Always disconnect the power
before working on the device.
Dangerously high voltages of ≥50 V may still be present 10 min.
after the power is cut (capacitor charge). So check that electrical power is not present!
Work on the device must only be carried out after the DC link voltage has dropped below a
residual voltage of 50 V (indicated by monitoring
LED H1 and to be measured on terminals X1/L-
and L+).
A dangerous voltage may be present at the device, even if the device does not emit any visual
or audible signals/indications (e.g. with mains voltage applied to terminal X3 and missing control
24 V on X2)!
The following general guidelines apply for the installation of Servo Drives:
y
Compliance with the EMC product standard
− Commissioning (i.e. starting intended operation) is only permitted on compliance with the
EMC product standard
IEC/EN 61800-3.
The installer/operator of a machine and/or system
must provide proof of compliance with the protection targets stipulated in the standard.
y
Cable type
− Use only shielded mains, motor and signal lines with double copper braiding with 6
0 to 70 %
coverage.
y
Cable laying
− Route mains, motor and signal cables separated from one another. If possible, keep a
distance of at least 0.2 m (0.66 ft), otherwise use separators. They should not run in parallel.
If crossovers are unavoidable, they should wherever possible be configured perpendicular (at
a 90° angle).
− Always route the motor cable without interruptions and the shortest way out of the control
cabinet. When using a motor contactor for example, the component should be directly
mounted to the
s
ervo
d
rive and the shielding of the motor cable should not be stripped back
too far.
− If possible signal lines should only enter from one side into the switch cabinet.
− Lines of the same electric circuit must be twisted.
− Avoid unnecessary cable lengths and loops.
y
Earthing measures
− Earthing measures of relevance for the
s
ervo
d
rive are described in section “4.6 Protective
y
Shielding measures
− Do not strip the cable shields back too far, and lay them with large area connections both on
the component and on the backing plate or on the PE rail (main earth) for the backing plate.
y
External components
− Place larger loads near the supply.
− Contactors, relays, solenoid valves (switched inductances) must be wired with suppressors.
The wiring must be directly connected to the respective coil.
− Any switched inductance should be at least 0.2 m (0.66 ft) away from the process controlled
assemblies.
y
Additional information
can be found in the corresponding connection description.
