Installation
WARNING!
Risk of personal injury.
• Only a competent electrician may install Fan Starter.
• Turn off and lock the main switch during installation.
• Install a separate safety/maintenance switch close to the fan if the fan and
Fan Starter are mounted in different locations.
• If start signal is activated, the fan will automatically start after a voltage drop
out.
• Even when the Fan Starter is turned off, there may be external control voltage
at terminal X1.

the carrier and the local Nederman representative immediately.
4.1.1
Fan Starter 5.5, 5.5 PTC installation
NOTE!
See the electrical diagrams included with Fan Starter.
NOTE!
Always pay attention to local legislation when sizing the cables and
fuses.
Dimension the cables and fuses in accordance with the motor current.
Too little space in a 24 V system can cause a poor short circuit protection. So
for terminals 3-116, use a cable with a minimum diameter of 1,5 mm
cable is up to 10 meters long. Use a cable with a minimum diameter of 2,5 mm
if cable is between 10-20 m long. Use a larger cable if its length is longer than
20 meters.
The current value for the motor overload protector has to be set. See the motor
plate.
NOTE!
For NCF EX shall the value be maximum 0,9 x normal value.
Connect the motor according to the electrical diagrams. Check that the fan
rotates in a clockwise direction. If it is necessary to change the fan rotation
direction, it is important to do it in accordance with the electrical diagrams.
Install a separate safety/maintenance switch close to the fan, if the fan and the
Fan Starter are mounted in different locations. Connect the control contact in
the safety/maintenance switch to Fan Starter (terminals 109-110).
To make the fan start more easily, the airflow could be restricted by a damper
during the fan start. FilterMax has a function to delay the opening of the down
time damper at fan start. If FilterMax and a down time damper is installed, set
the "dA" time according to the actual fan start time. See figure 2.
NOTE!
See FilterMax instruction manual.
