PERSONAL PRECAUTIONS:
♦ Someone should be within range of your voice or close enough to come to your aid when you work near a battery.
♦ Have plenty of fresh water and soap nearby in case the battery electrolyte contacts skin, clothing, or eyes.
♦ Wear complete eye protection and clothing protection. Avoid touching eyes while working near a battery.
♦ If the battery electrolyte contacts skin or clothing, wash immediately with soap and water. If the electrolyte enters the
eye, immediately flood the eye with running cold water for at least ten (10) minutes and get medical attention
immediately.
♦ Never smoke or allow a spark or flame in vicinity of a battery.
♦ Be extra cautious to reduce risk of dropping a metal tool onto a battery. It might spark or short-circuit the battery or
other electric part that may cause an explosion.
♦ Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery

Description:
The PC63 Cage is intended to be installed in a protected environment. The cage can have several
different combinations dependant as to what has been ordered. Either four A63s or two A63s and a
TPCD, can be inserted in a PC63 cage. The TPCD distribution panel is always inserted in the third
and fourth slot. The slots are numbered from 1 to 4 from left to right.
Although a PC63 cage can accept more than one A63 module, it does not need more than one to
power the load.
All A63 rectifiers must be plugged into the proper voltage cage. (i.e. 24V A63 into 24V PC63)
At least 6 inches of room should be provided in front and the rear of the PC63 cage for ventilation.
The PC63 cage can be mounted either in a 19” or 23” rack using the standard brackets provided. It
can be mounted flush to the rack or midway.

Input DC:
The A63 module has the input voltage range from 105Vdc to 150Vdc. No taps, jumpers, straps or
circuit breakers need to be changed. The input d.c. voltage terminal block is located on the backside
of the cage. (Each A63 converter has an input d.c. breaker.) Each converter draws approximately 10
amps.
Output DC with A63 Converters ONLY –
no distribution center (TPCD)
:
All A63 outputs are paralleled and brought to the PC63 cabinet d.c. output terminals. When
connecting the PC63 cage to the termination split buss, use both terminals located on the back of the
PC63 cage. Each terminal block will provide 60A of current up to a total of 120A.
The rear panel of the PC63 does not have to be removed to connect to the d.c. output terminals.
Remove the d.c. terminal cover to gain excess to the d.c. terminals. The d.c. cables can be passed
thru the holes on the PC63 cage or ½” conduit can be attached to the PC63 cage at the Feed Thru
holes. Remove the rear panel to access the rectifier failure alarm (RFA) terminals.

Connect positive and negative wires from TPCD to the back plane of the cage (OBSERVE PROPER
POLARITY). Connect load positive to common load positive buss bar. Connect negative to load
negative terminal block.
Rectifier Failure Alarm Terminal:
The rectifier failure alarm terminals RFA1 and RFA2 are located on the rear of the PC63 cage. Each
A63 has a separate rectifier failure dry form “C” contact labeled A, B, and C. A to B is the normally
open contact and B to C is the normally closed contact. The maximum wire size for the alarm terminal
blocks is 12 gauge. The contacts are rated at 0.4 amps @ 120Vac or 1.25 amps @ 24 Vdc.
The rectifier failure is alarmed, with a loss of d.c. input voltage, low d.c. output voltage, high output
d.c. voltage, high temperature or improperly inserted A63 module.
