Platinum Z5 CD - AC Input Connection

2-12 888-2408-002
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 560-0042-000, quantity 8).
For safety reasons, you also must install a 4 pole disconnect device if your neutral
line is not connected to earth ground.
2.5.6.2 AC Input Connection
AC connections are made to the top of the main
contactor K1, located in the top righthand
corner in the back of the transmitter. Bring the
ac wires through the holes in the top of the
transmitter and connect to the top terminals on
contactor K1. Access is also available through
the bottom of the transmitter.
For 380VAC (342 - 432VAC) 3 Phase 4-wire
systems, there is also a large insulated standoff
located near the main contactor for the
NEUTRAL connection.
!
CAUTION:
THE NEUTRAL CONNECTION IS EXTREMELY IMPORTANT IN 380VAC 4
WIRE 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 transformers in the transmitter will be configured as
delta for this application.
