ASSEMBLY AND INSTALLATION
3
▸
Set motor circuit breakers according to the blower connection data (see Technical Data
for purge air unit) to a value 10% above the rated current.
▸
Check the function and running direction of the blower (purge air flow direction must
match the arrows on the inlet and outlet openings on the blower). For wrong direction on
3-phase motors: Swap power connections L1 and L2.
▸
Connect the pressure controller (option) to monitor purge air feed.

NOTE:
In case of doubt or when using a special motor version, the operating
instructions supplied with the motor have priority over any other informa-
tion.
NOTE:
▸
Use a fail-safe power supply (standby unit, rails with redundant supply)
▸
Fuse the purge air unit separate from the other system components. The
fuse type must match the rated current (see technical details of purge air
unit). Fuse each phase separately.
Use circuit breakers to prevent phase failures on one side.
NOTE:
The purge air available onsite must be free from dust, oil and condensate.
The adapter for instrument air supply can be supplied with a reducing nipple for other
adapter threads on request.
