Electrical data, connections and wiring
Compressor electrical
specifications
Compressor rated voltage (V) Model RW(Ω) at 20°C line to line Max Operating Current (A)
400 VLZ065-G 0.177Ω±7% 19
RW: Winding resistance per winding, measured at motor terminals
Because VLZ compressors are powered by a
frequency converter, the mains frequency, 50 or
60 Hz, is no longer an issue. Only the mains
voltage is to be taken into account. Never
connect the VLZ compressor directly to the mains
power supply in case of motor burnt.

MOC (Max Operating
Current)
Wiring connections
Max. operating current is the max. continuous
current output from drive to compressor within
operating map. MOC is tested at max. load condition with
nominal voltage. MOC is printed on the
nameplate, it can be used to select cable and
contractor for customer by adding some safety
coefficient.
Electrical power is connected to the compressor
terminals by Ø 4.8mm (3/16") screws. The
maximum tightening torque is 3Nm. Use a 1/4"
ring terminal on the power leads.
Terminal cover mounting
The terminal cover and gasket should be installed
prior to operation of the compressor. The terminal
cover has two outside tabs, 180 degrees apart, that engage the terminal fence. When installing
the cover, check that it is not pinching the lead
wires.
