WARNING
All work done on a disconnected and secured against re-start locked low volt‐
age machine is to be carried out by skilled personnel. This is also valid for
auxiliary currents (like temperature sensors).
All work must be carried out at motor standstill. Motors with permanent mag‐
net field strength create at rotating rotor a voltage > 60V on the motor con‐
nections.
Note for Assembly
●
Flameproof joints must be opened and jointed during assembly opera‐
tions. Avoid damage on the flameproof joints. Do not remove existing
assembly grease. Let the o-rings in their factory-adjusted position. Work
in a clean environment.
●
When assembly damage on the flameproof joints occured, the motor
must be repaired with original spareparts by the Rexroth service.
●
Lid screws are coated. By screwing in and out the screws, the coating
wears. Use the enclosed screws at assembly. Secure the lid screws
with Loctite 243® at re-assembly.
Connection ready-made cables
1. Remove Ex-screw connection for encoder cables, use screw connection
on the ready-made cable. Tighten the screw connection with 50 Nm in
the lid housing.
2. Insert the power cable into the lid housing and tighten the Ex-screw con‐
nection.
