Cable connection
Feed the voltage supply cable and the shielded motor
cable through the screwed cable glands into the VARI-
PACK frequency inverter and connect them to the
power terminals. Observe the tightening torques of the
terminals see chapter Cable cross-sections and tight-
ening torques, page 13!
• Connect the voltage supply cable to the terminals
L1, L2, L3 and the protective earth terminal. Phase
sequence is not important.
• Connect the motor cable to the terminals U, V, W
and the protective earth terminal.
• Observe the information regarding electromagnetic
compatibility (EMC) see chapter Electromagnetic
compatibility (EMC), page 20!
5.7 Control connections (inputs and outputs)
Information
The entire external wiring must be approved for
maximum system voltage!
All control and signal terminals ensure safety
extra low voltages (SELV), i.e., they are protec-
ted by double insulation.
Specification of the control connections:
• Cables with insulated or uninsulated wire end fer-
rules: 0.25..1.5 mm².
Digital inputs
• Function
– 2: DI1 (Start)
Compressor start command.
– 3: DI2 (Force)
Operation of the compressor with a configurable
frequency (50Hz factory setting).
– 4:DI3 (Reset)
