5.3 CONNECTING THE APPLIANCE TO THE POWER MAINS
Only appropriately trained technicians are allowed to connect the appliance to
the electrical current. They must follow installation instructions and observe the
occupational safety regulations applying in the country in which the appliance is
being installed. They must read the instructions carefully and above all
thoroughly familiarize themselves with the sections on REQUIREMENTS AND
CONDITIONS FOR NORMAL OPERATION OF THE APPLIANCE and the
machine’s electrical circuit scheme.
Before connecting the appliance, all attachments that might have become loose
during transportation must be checked. Attachments that may have become
loose or disconnected must be screwed back on and tightened.

Connecting instructions for five-vein cable (three-phase appliances – 400/50/3):
A test start-up of the appliance is carried out by trained electrician after the
connection to confirm correct operation. (see the section on MAINTENANCE).

in the correct direction regardless of the connecting position of either of the
phases.
After appliance has been connected, trained electrician should also control the
power consumption. The current must not exceed the maximum allowed on the
identification sticker (see the section GENERAL FEATURES AND
SPECIFICATIONS).
