Connecting the power supply
The power connection to the
SMART-SN
fan is made by the user on his own – see the instructions in point
6.3. This should be done by an employee with proven qualifications.
On a separate customer order, the manufacturer provides a
service switch
, which is necessary to disconnect
power during installation and service – see above – Table 6.
The customer installs the service switch himself. The way of connecting the service switch is shown below –
see Diagram 1 and Diagram 2.
Before connecting the fan to the power supply, remove the fan cover to gain access to the motor junction box.
After completing the connections, replace the fan cover.
