RW: Winding resistance per winding, measured at motor terminals
RLA: Rated load Amp
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 2 motor
voltage codes, the most common mains voltages
and frequencies are covered. Never connect the
VZH compressor directly to the mains power
supply in the case motor burns out.

Rated Load Amp value is the current value at
maximum load, in the operating envelope, and at maximum speed and maximum drive input
voltage. RLA (Rated Load Amp)
Max Operating Current (A)
Wiring connections
Max operating current is the maximum
continuous current which is 115% of RLA. This
value is printed on compressor nameplate.
VZH scroll compressors will only compress gas
while rotating counter-clockwise (when viewed
from the top of the compressor).
The drawing shows electrical terminal labeling
and should be used as a reference when wiring
the compressor.
U, V & W of the drive and the compressor must be
connected accordingly.
For use of EMC bracket with shielded cable, it is
recommended to have a thread cutting screw
(#10-32) having a torque of 3NM.

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.
