3.3.1

Voltage supply of the peripheral devices

The compressor module internally supplies voltage to
peripheral devices (solenoid valves, slider position in-
dicator, oil and oil filter monitoring and/or oil heater)
and to the terminal strips CN7 to CN12.
3.3.2

Rotation direction monitoring fuse (F08)

The HS. and CS. compressors incorporating the com-
pressor module are equipped with the F08 fuse in the
terminal box. It protects the rotation direction monitor-
ing lines between terminal box and module housing.

Such a fuse is also required with open compressors
between module housing and motor terminal box when
the rotation direction monitoring function of the com-
pressor module is used.
Technical data of the installed fuse:
• Rated current 1 A
• Release speed FF (very quick acting)
• Rated breaking capacity of 50 kA at 700 V AC
• Dimensions 6.3 x 32 mm
