7.4 Setting the overload protection cut---out
Compressor motor:
In the star---delta configuration the phase current is fed via the overload protection cut---
out. This phase current is 0.58 times the rated machine current (see nameplate in the con-
trol cabinet).
To prevent the overload protection cutout from being triggered by voltage fluctuations, tem-
perature influences or component tolerances, the setting can be higher than the arithmeti-
cal phase current.
7.5 Motor Protection Switch Setting
Fan motor
In direct on---line start the starting current is fed via the motor overload protection switch.
To prevent the overload protection switch from being triggered by voltage fluctuations, tem-
perature influences or component tolerances, the setting can be higher than the motor
rated current (see motor nameplate).
7.6 Pour cooling oil into the airend.
Material: 1 l cooling oil
The airend must be manually filled with cooling oil before initial start---up and after being
out of use for more than 3 months.
