 Install suitable folded spiral-seams duct.
 Make sure that the ducting is not twisted
during installation.
7.2 Electrical connection
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-connections and make
sure there is cable tension
relief.
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.
● The speed of EDR 25, EDR 31, EDR 35,
EDR 40, EDR 45 and EDR 50 units can be
controlled with transformers. A suitable
speed controller for the stated current input
should be chosen. Speed control through
the use of phase angles is not permitted.
● The speed of EDR 56, EDR 63 and EDR 71
units can be controlled with frequency
converters. Speed control with trans-
formers is not permitted. On/Off only if
there is no frequency converter.
Procedure:
 Remove the terminal box cover and take
out loose components.
 Make a hole in the terminal box at one of
the breakout points.
 Install cable screw-connection [5].
CAUTION
Danger of short-circuits
caused by damp if the power
cable is not inserted correctly.
 Insert the power cable
correctly.
 Insert the power cable into the terminal box
such that the cable screw-connections fits
tightly round the power cable.
 Connect the power cable to the connection
terminal [6] as shown in the wiring diagram
on Page 20.
WARNING
Danger of short-circuits
caused by pulling the power
cable out.

Secure the power cable with
the tension relief.

Install the supplied tension relief [5].

Connect the EDR 31, EDR 35, EDR 45 and
EDR 50 units fans to suitable triggering
devices, e.g. MVE 10 motor protection
switch. The triggering device may not
switch itself
back on automatically after triggering.
 Connect EDR 56, EDR 63 and EDR 71
units to frequency converters.
7.3 Start-up
 Before start-up, ensure that there are no
objects, small parts, dirt, etc., in the ducts.

Check that the technical data has been
adhered to, by reference to the rating plate.

Ensure that the air can flow unhindered.
 Carry out a function test. Check that the
impeller runs quietly.
