NOTICE:
It is the compressor owner's responsibility to:
1. Verify that the receiver and the receiver installation comply with the
applicable local, state, and national codes.
2. Obtain the proper licenses for the receiver.
3. Arrange periodic inspections necessary to maintain those licenses.
2.8. Wiring
It is the compressor owner's responsibility to ensure a safe
installation that complies with applicable local codes and the
National Electrical Code (N.E.C.). This includes properly sized
short circuit and ground fault protection, power connection wire
sizing, and equipment grounding. The wiring schematic and
CSA label, provided with the assembly, must be consulted. Be
sure the freeze protection and engine block heater(s) are wired
for the proper voltage and agree with the plant power system.
The external connections are 120VAC male plugs designed for
standard extension cords. Note that current draw for the engine
jacket water heater may use up to 30 Amps. (See
FIGURE 6A/B
for location on
assembly). There is a 120VAC convenience outlet on the exterior of the compressor for
use with an air dryer or auxiliary pump. Maximum current draw is 400W @ 120VAC. If
the current for that circuit is exceeded beyond the design of the integral 24VDC-120VAC
power inverter, or if the output is short
circuited, it will automatically shut off. The
inverter will then need to be power cycled to
reset the trip. Always repair the short circuit
or high current draw before restarting the
inverter, or it may be damaged. The inverter
is in a junction box mounted to the
compressor inlet air filter stand, accessible
through the front door (adjacent to the HMI
control panel).
Normally, the engine alternator recharges the 24VDC engine batteries. However, an
integral battery charger is hardwired to the battery terminals and is meant to be used
when storing the assembly. The operation of the charger is automatic, so long as the
120VAC power is connected at the exterior connection, adjacent to the engine block
heater and other freeze protection circuitry.
The compressor PLC will automatically control the starting, operating, and stopping
sequences. The controller also monitors critical parameters during operation and
provides for protection of the compressor in the event of a problem. The Description of
Operation provides more information on the controls.
