PCM500 SERIES
OPERATING MANUAL
compatible with the PCM500 J1-J4 connectors. Compatible cables are
available from UNIPOWER Telecom; contact the factory. If another
manufacturer’s rectifiers and shelves are used, they must be properly con-
nected, pin for pin, to be compatible with J1-J4 as shown in the “Signal
Connectors” table. The AC Good and DC Good functions must give a TTL HI
or Open for a fault, and the remote adjust input range must fall within 0V to
+5V.
18.3
Set the appropriate Alarm-Enable DIP switches to the enable (right) position
for the alarm functions used. All others must remain in the disable (left)
position.
18.4
Make all the Alarm Input connections to TB1 from the fuse/circuit breaker
panels and the low-voltage disconnect panels. These inputs must be “nor-
mally closed” but go to an “open” for an alarm condition. Numbers 14 to 22
AWG wire size may be used on all TB1 terminals.
18.5
Make all Alarm Output connections to TB1 for the alarm functions used.
These connections (terminals 13-36) are Form C relay outputs. “Normally
Closed” (NC) means a “short” between this terminal and the “common” (C)
terminal when the function is operating properly with power applied. “Normally
Open” (NO) means an “open” between this terminal and the “Common” (C)
terminal when the function is operating properly with power applied. The only
exception to this is the EQA (equalize alarm) function; this function is defined
as “Normal” when the EQ/FL switch is in the FL (float) position. An alarm is
created when the switch is in the EQ (equalize) position; the EQA yellow LED
also turns on.
18.6
Determine which side of the shunt goes to the battery floating terminal. Do
not connect to battery yet. Connect leads from each side of the shunt, with
proper polarity, to the TB1 shunt input terminals, I+ and I- (terminals 41 and
8 respectively).
18.7
If the battery temperature compensation is used, connect the leads from the
probe to TB1 TC terminals 9 and 40. There is no polarity to this connection.
The probe should be installed on or near the battery as discussed in Section
16.3.
18.8
With the rectifiers still off, connect the B+ and B- inputs to TB1 (terminals 10
and 11 respectively) to the positive and negative common rectifier distribution
buses.
