Because VZH 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. With 3 motor
voltage codes, the most common mains voltages
and frequencies are covered. Never connect the
VZH compressor directly to the mains power
supply in case of motor burnt.

RW: Winding resistance per winding, measured at motor terminals
RLA: Rated load Amp
Rated Load Amp value is the current value at
maximum load, in the operating envelope, and at
maximum speed and rated drive input voltage.
Max operating current is the maximum
continuous current which is 115% of RLA. This
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.
The terminal cover and gasket should be installed
prior to operation of the compressor. The terminal
cover has two outside tabs, 180 degrees apart,
