DANGER
There is a risk of injury by electrical shock!
❚ The electrical connections must only be made by skilled personnel!
❚ Only carry out connection work when no voltage is applied (no live parts)! There is a risk of
unintended start-ups or electric shock.
NOTICE
❚ Make sure that the supply voltage corresponds to the data on the name plate.
NOTICE
❚ If an emergency stop is carried out without the required suppressor circuit, the control unit
may be destroyed.
❚ Observe the correct polarity of the suppressor circuit!
NOTICE
❚ To functionally test the individual brake circuits, the power supply must be able to be
switched off individually. For a new over energisation when switching on, it is also neces-
sary to open switches K1/K3.
❚ The protective circuitry contained in the INTORQ switching device BEG-561-
(terminals 3 and 4) is not permitted for use in the lift system. The protective circuitry
must be connected parallel to the brake coil ( 32).
