motors must not exceed the per-
missible switching capacity of the
control unit.
The thermal contacts of all motors
must be connected in series.
Note on safe operation
Earthing, multiple earthing or
protection switching and mains
protection must be carried
out on-site according to VDE
specifications and the regulations
of the responsible electricity supply
company. Only specialists may
establish electrical connections
based on the wiring diagrams in
compliance with the applicable
regulations, taking into account
local regulations.

Reconnection after a fault
In the event of a fault, the unit
switches off and does not switch on
again automatically. After clearing
the fault, the unit can be switched
on again by setting the control
switch to “0” and waiting for
about30 seconds.
Multiple series connection
The control unit is suitable for
