WARNING: Disconnect primary power prior to servicing.
Installation & Initial Turn-On
MOV protection may need to be modified. Please consult with an electrician if this
applies to your installation. If applicable, the phase-to-earth 275 volt MOVs in the
RV7 through RV13 and RV20 positions may be replaced with 510 volt MOVs
(Harris part number 5600042000, quantity 8).
For safety reasons, you also must install a 4 pole disconnect device if your neutral
line is not connected to earth ground.
NOTE:
Install the exciter input cables in a metal conduit which is separate from the
AC supply. Remote control cabling may be included in the same conduit with
the exciter cabling. AC power wiring and small signal lines should never be
put in the same conduit.
2.5.6.2 Three Phase AC Connection
AC connections are made to the top of the AC
mains contactor K1. K1 is on the top right side in
the rear of the cabinet. There is also a large
standoff located near the main contactor for the
NEUTRAL connection in 380VAC (342-
432Vac) 4-wire WYE systems. Bring the AC
wires through the holes in the top of the
transmitter and connect to the top terminals on
contactor K1.
!
CAUTION:
THE NEUTRAL CONNECTION IS EXTREMELY IMPORTANT IN 380VAC 4-
WIRE WYE APPLICATIONS. BY VIRTUE OF THE SINGLE PHASE LOADS
WITHIN THE TRANSMITTER, THE SYSTEM IS NOT ENTIRELY
BALANCED, REQUIRING NEUTRAL CURRENT TO MAINTAIN PROPER
PHASE TO NEUTRAL VOLTAGES. A POOR NEUTRAL CONNECTION
COULD CAUSE DAMAGE TO THE SINGLE PHASE ELEMENTS IN THE
TRANSMITTER.
NOTE:
The NEUTRAL connection is NOT required for 208/220VAC 4-wire
WYE source voltage and should not be run to the transmitter. There is no
connection in the transmitter for the neutral connection (for this application)
and it should not be connected to chassis ground. The power supply trans-
formers in the transmitter will be configured as delta for this application.
