DANGER
Danger to life from electric
shock.

Switch the mains fuse off.
 Position a warning notice to
avoid the unit being
accidentally switched back on.
CAUTION
Danger of short-circuits
through incorrect feeding of
the power cable into the
terminal box.
 Feed the power cable
correctly through the cable
screw-connection.
Notes
● Always note the relevant specifications
for electrical installations and when fitting
equipment. In Germany observe DIN
VDE 0100 and the corresponding parts
in particular.
● The cabling between the power and the
terminal box must be permanent.
● Units are speed controllable with
● frequency converters (only DSQ..
and DSQ.. K) or
● transformers. Select the best option
depending on the current input. Speed
control through the use of phase angles
is
not permitted!
Connect the unit electrically

In the case of standard units, remove the
side panel [3] and feed the power cable
through the cable screw-connection [6] in
the housing. Ensure that the cable screw-
connection seals off the power cable
tightly. The cable screw-connection also
serves as a tension relief.
 Remove the terminal box cover.
CAUTION
Danger of short-circuits
caused by damp if the power
cable is not inserted correctly
into the terminal box.
 Insert the power cable into the
terminal box such that the
cable screw-connection fits
tightly round the power cable.
 Connect the power cable to the connection
terminal [7.1] or [13.1] respectively, as
shown on the inside of the terminal box
cover.
 Connect a suitable motor overload protect-
tion device.
 Put the terminal block cover on and screw
it into place.
 In the case of standard units, fit side
panel [3] and secure with the two
catches [3.1].
