7.1.4 Checking the direction of rotation of the motor
DANGER
Danger to life due to electric voltages!
Contact with live parts leads to death or serious injuries.
Work on the electrical unit may be carried out by an electrician only.
Make sure that the unit is tension-free for the necessary work.
Switch off the unit and secure it from being accidentally switched on again.
Do not make any changes in the motor terminal box.
Before switching on the unit, make sure that all panels have been fitted prop-
erly.
NOTICE
Material damage due to incorrect direction of rotation of the unit!
The integrated oil pump lubricates the compressor block only if the direction of ro-
tation is correct. Inadequate lubrication can lead to damage to the unit within a
few seconds.
Ensure that the direction of rotation of the motor corresponds to the direction
of rotation arrow on the unit.
1.
Switch on the unit and switch off after max. 2 seconds.
2.
Check the direction of rotation of the motor immediately after switching on
with the direction of rotation arrow on the unit (Position and appearance of the
rotation arrow can vary, depending on the unit): or
Does the direction of rotation of the motor not correspond with the direction of rota-
tion arrow on the unit?
Swap two of the three phases at the input terminals in the switchgear box.
