General Notes
General
The following work must be done by qualified personnel according to the lo‐
cal regulations.
Danger to life due to electrical voltage! Han‐
dling within the area of live parts is extremely
dangerous.
WARNING
All work on the electric system may only be done by skilled electricians. Tools
for electricians (VDE tools) are absolutely necessary.
Before working:
1. Isolate (even auxiliary circuits).
2. Ensure that the main switch cannot be accidentally
switched on again.
3. Ensure de-energization.
4. Ground and short-circuit.
5. Cover or fencing off neighbored, live parts.
Before start working, check with possible live parts a suitable measuring de‐
vice (e.g. with capacitors). Wait for their discharging time.
Power connection
Before connecting the motor, check whether the power supply and power fre‐
quency consist with the nominal data. A connection overview for power and
accessory connections (PTC) can be found within the terminal box. The con‐
nections must be established such that a permanent safe electrical connec‐
tion is ensured. This is also valid for power, grounding and shield connection.
Power cables
Power cables for motor connection are not in the scope of deliv‐
ery of the motor. Selection and assembly of suitable cables must
be done by the customer.
When selecting cables, please proceed very carefully and ob‐
serve the requirements existing at the installation space of the ca‐
bles.
Observe features, like
●
resistance against coolants and lubricants from machining
●
compliance of EMC directives
●
fatigue limit
●
non-halogen
We recommend to do crimping connections according to IEC
60352-2. Malfunctions or damage due to wrong or improper motor
connection are not in the liability of Bosch Rexroth.
