♦
Ensure that the fan and all its components are
undamaged.
♦
Fit the fans in such a way that there is sufficient
access for installation, troubleshooting, maintenance
and repair.
♦
Protect against dust and moisture when installing.
♦
Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦
If harmful or hazardous products are transported,
check the general condition of the fan before opening.
Important
Damage to the bearings or other parts of the fan can
occur.
♦
Do not place a duct bend directly before or after
the fan!
♦
Ensure a smooth and constant air flow to the
device.

Electrical connection
Safety information
♦
Observe 2
♦
Prevent the ingress of water into the connection box.
Warning: Danger due to electrostatic influence on medical implants (e.g. cardiac pacemaker)!
♦
Persons with medical implants (e.g. cardiac pacemaker) should keep enough distance to the fan.
Connection
♦
Check if the data on the nameplate matches the
connection data.
♦
Complete the electrical connection according to the
circuit diagram.
♦
Fans with EC- motors must be switched on/off via the
control input.
♦
Connect the cable end in a dry environment.
♦
Install a circuit breaker in the permanent electrical
installation, with a contact opening of at least 3 mm
at each pole.
♦
Potentially, the fans may become charged with static
electricity. If this represents a risk, please contact
Systemair.
Protective grounding wire
The protective grounding must have a cross-section equal to or greater than that of the phase conductor.
Residual current circuit breaker
All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60
Hz, in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies
(UPS).
