Mounting instruction - fig. 1
1. Check that the damper blade in the damper housing is in
a completely closed position. Then fit the damper in the duc-
ting system on the inlet side of the fan. For safe connection 3
self-drilling screws in each duct connection is recommended.
Check the shaft end position for closed damper position ac-
cording to picture.

according to picture. Push the button (A).
3. Fit operation box on the wall near to the operators working
area.
WARNING!
Risk of personal injuries.

before any electrical work is started.
Electrical Installation of Damper Motor and
Accessories - fig. 2
Electrical installation of the damper system should be
done by a qualified electrician.
Connection should be done according to the wiring diagram.
1. Connect the cable between the damper motor and the
operation box. 3 x .0 mm

2. For damper systems with sensor; connect the sensor ca-
ble in the operation box.
3. Connect possible spotlight or circuit-breaker for Nederman
Extractor arms.
Check correct voltage connection: block J6.
D3 = light emission diode for voltage connected.
Delay time
The damper system with sensor shuts the damper automati-
cally after welding, with a delay time of  minute. This delay
time can be adjusted with a potentiometer positioned in the
operation box (see picture). The time can be adjusted bet-
ween 0 and 5 minutes +/- 25 %.
Motor Damper
cable is recommended.
This product is designed to meet the requirements of the

To start the fan, when any damper is opened, the fan contac-
tor should be connected to block J2 in one of the operation
boxes.
Alternative A
The internal power supply on 24 V AC maximum 80 mA (2 VA)
is used to the fan contactor (Nederman product).
Connect a cable 2 x .0 mm
J2:B. Connect a cable  x .0 mm
Alternative B
The power supply to the fan contactor (not a Nederman pro-
duct) is supplied from an external source, maximum 48 V, 5 A.
Connection to Motor Operated Exhaust Hose
Reels
Connections to Nederman motor operated exhaust hose re-
els should be done according to wiring diagram no. 48346.
Lockable safety switches are recommended for the
whole electric system including the fan.
