Electrical work
Before carrying out electrical work:
Warning! Risk of electric shock!
Install circuit breakers for personal protection.
Any work on the electrical equipment of the machine shall only be performed
by professional electricians!
For the power lines, use standard cables of sufficient capacity. Otherwise
there is a risk of short circuits, overheating or fire.
When installing power lines, do not apply tension to the cables. Loosened
connections pose a risk of cables slipping from terminals or breaking; this can
result in overheating or fire.
Should it be necessary, disconnect all feed lines from the house fuse box.
Risk of total loss!
The device may only be switched on when the hydraulic circuits are completely
filled and vented, and all electrical connections are properly.
