DANGER
Electrical connection work performed by an unqualified individual.
Risk of death by electric shock!
 All electrical connections are to be established by an authorised professional only.
 Settings and adjustments on the control system as well as the commissioning of the control system are to be
carried out by qualified persons only.
 The electrical connection must comply with the standards in force in the country where the appliance is
installed.
The left cable gland is intended for the cable entry of the mains cable. The separate cables are to be clamped into the termi-
nals in the manner described below. According to the motor which is used, a single-phase or a three-phase connection can be
established.
NOTICE
 The power supply has to be secured by an independent all-pole fuse which can be switched off (max.
20 A).
