A36F - 3 PHASE - INSTRUCTIONS AND TROUBLESHOOTING

Page 10 of 21

COPPER WIRE (KS5482-01)
WIRE SIZE REQUIRED

CMA =  

(A*LF*K) / AVD

CURRENT CAPACITY (IN AMPS) (SEE TABLE 3)
MAX AMPS =  (CMA* AVD)/(LF*K)

8.0 ELECTRICAL CONNECTIONS & FIELD WIRING

Terminal blocks are provided for connecting the a.c. input and d.c. output.  A ground wire must be

connected to the unit’s case ground.

8.1

A.C. INPUT

Make sure that a.c. power is off at the main a.c. breaker box before installation begins.

Make sure that the input source is the same voltage and frequency as that which is marked on the
nameplate of the rectifier.  On  multivoltage, input units check tap jumpers with the unit to make sure

they agree with input voltage.

The wire size and distribution fusing should be adequate for the nameplate input current of the rectifier

plus the overload current (usually 10%-15% higher than the nominal rating).

An adequate earth ground lead should be connected to the terminal marked “GROUND” or “GND”.

8.2

D.C. OUTPUT

Make sure that the battery voltage and cell type, which is being connected to the rectifier, matches the
rectifiers output voltage and cell type.

***OBSERVE PROPER POLARITY! ***

The negative wire from the battery must be connected to the terminal marked “NEGATIVE” or “NEG” and
the positive wire from the battery must be connected to the terminal marked “POSITIVE” or “POS” on the

rectifier.

To prevent the d.c.  output fuse  from  blowing   when connecting the   battery,  connections to the

power supply and  batteries should be done in the  following order (single power supply).

1.

 

Connect a.c.  input line to the terminal block provided.  Be sure the main a.c. circuit breaker is off.

2.

 

Observe the polarity of the battery cables and the rectifier output.  Connect the negative battery

cable to the negative rectifier output terminal.

3.

 

Energize the unit by turning the main a.c. breaker to the “ON” position, and then turn on the

chargers’ a.c. breaker.   This will charge the capacitors inside the power supply and eliminate heavy
arcing when the remaining battery cable is connected.  After approximately one (1) minute, turn off
the chargers’ a.c. breaker and immediately connect the remaining battery cable.

4.

 

Connect the loads.

5.

 

Turn the chargers’ a.c. breaker to the “ON” position again and the charger will commence charging

the batteries and powering the load.
