277V Input Power & Field Connection Diagram
(
See pages 11-13
for control wiring information)
Note that regulation at 277V is inferior to using 240V
. 277V operation is provided
for convenience and ease of installation.
This connection is typically used on generators with full load field voltages of 63VDC or
less and full load exciter field amperage less than 12ADC.
Note that the maximum input voltage to the XC14
Voltage regulator in this
connection is 277VAC!
DO NOT input 480VAC into the XC14
in this connection!
Regulation problems or damage to the unit may result! For use on 480V systems,
connect the regulator from Line to Neutral T7 and T0 (
See Pages 6 and 7
), or use a
480-240V step-down transformer rated at 1KVA
.
Diagram Assumes a 480V Generator
For other voltages, use a 1KVA
(or larger)
Transformer
with a
240V Secondary
.
NEVER install a switch or
breaker on the DC or Exciter
side of the voltage regulator!
Only install a switch or
disconnect on the AC Side of
the regulator!

NOTE:
It is not necessary
to jumper terminals
R1 and R2 if not
using the Remote
Voltage Adjustment!
NOTE:
Jumper
X & Y if
generator
is not
paralleled!
NOTE:
Use switch rated:
20A @ 480VAC
