1-4-1 BYPASS SWITCH
The bypass switch is located on the front panel. See Illustrations 1-5, 1-6, and 1-7. The switch bypasses the
voltage regulation electronics but maintains the functioning of the voltage change/isolation transformer between
the input and the output. In the AUTO position, the output voltage is regulated. In the MAN (manual) position,
regulation logic is bypassed and input power is applied to load via the transformer without regulation. Select the
MAN position if there is a problem with the regulation logic circuitry. Refer to section 1-7-2, Non-regulating
Condition for the procedure to operate the unit in the bypass mode.
1-4-2 Main Input Circuit Breaker (IMCB)
The Input Main Circuit Breaker (IMCB) located on the front panel of the unit, is used to switch power to the unit
On and OFF. See Illustrations 1-5, 1-6, and 1-7. An optional IMCB is shunt tripped on the Constant Power 6 by
activation of a solenoid within the breaker when an optional remote Emergency Power OFF (EPO) switch is
activated. Also the optional Two Stage Thermo Repo station can be used to trip the IMCB. The Manual Restart
option will trip the IMCB if input power to the Constant Power 6 turns off. If the IMCB is shunt-tripped, refer to
Section 4.2 - Miscellaneous Problems for the Reset Procedure. Be sure to observe ALL Warnings and cautions
when setting the IMCB to ON or OFF.
1-4-3 Power ON Indicator
The Power On Indicator is located on the front of the unit. See Illustrations 1-5, 1-6, and 1-7. This neon
indicating lamp is on when input power is applied and the IMCB is turned on. If the lamp is not ON, there is no
input power to the unit or the IMCB is not in the ON position.
1-4-4 Input Power Cord
The input power cord is supplied on all Constant Power 6, Constant Power 3, and Mini-Power. See Table 1-2 for
the connector and ampere rating.
All Constant Power 6 regulators have available input power of 480 VAC and the input power cord has no
connector.
