MODEL TPS - INSTRUCTIONS AND TROUBLESHOOTING INFORMATION
12 OF 20
CPN 40615
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.
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”.
Be sure the transformer taps are set for the correct a.c. input. An a.c. input tap setting card is located
inside the unit.
8.2
D.C. OUTPUT
Make sure that the battery voltage, which is being connected to the rectifier, matches the rectifiers
output voltage.
*****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 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 a.c. breaker to the “ON” position. 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 power supply and immediately connect the
remaining battery cable.
4.
Connect the loads.
5.
Turn the a.c. breaker to the “ON” position again and the rectifier will commence charging the
batteries and powering the load.
8.3
REMOTE VOLTAGE SENSING
Provisions for remote d.c. voltage sensing are provided. To use the remote sensing circuit remove the
wire from the positive d.c. output terminal to the RS+ terminal strip. Connect a #14 gauge wire from
the RS+ terminal to the positive battery terminal.
Caution: The polarity of the sensing is critical. Check and verify the polarity carefully.
