8 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 per-
formed by professional electricians!

For the power lines, use standard cables of sufficient capacity. Other-
wise there is a risk of short circuits, overheating or fire.

When installing power lines, do not apply tension to the cables. Loos-
ened connections pose a risk of cables slipping from terminals or break-
ing; this can result in overheating or fire.

Should it be necessary, disconnect all feed lines from the house fuse
box.
