Repair and Troubleshooting

Bosch Rexroth also recommends shielding solenoid wiring.
Do not use logical signals from the controller card (IE: "OK" signal) for switching
machine safety circuits
(see European Norm "Safety Requirements for Fluid Power Systems and Com-
ponents" EN982:1996).
If the control cabinet contains additional electrical components utilizing high voltage,
always observe safety standards to prevent accidents! Use appropriate protective
gear, such as safety shoes and safety gloves, when prudent!
Use appropriate tools (IE: insulated tools)
Before opening control cabinet doors, open the main disconnect.
To ensure safe working conditions, observe the following safety rules:
Remove all power
Ensure against unintended energization: lockout devices when possible, and use
lockout warning tags
Verify that voltage is not present
Cover or close off adjacent areas that are still energized.
If work on energized components is necessary, have a second per-son present as a
safety backup to actuate an E-STOP switch or open the main disconnect, if neces-
sary. Use insulated tools only.
