5.1

Resistance Test

Measure the resistance at each bus input with a multimeter connected to the BATT and RTN
input terminals. A resistance of at least 500 ohms should be read on the meter (some meters will
indicate a resistance of several Megohms because their input voltage is not high enough to break
down the forward conductance of the diodes used in the alarm circuit). Any resistance higher
than 500 ohms is acceptable. 

5.2

Wiring Connection Torque Measurements

Measure the torque of all input, output, and circuit breaker failure alarm relay contact
connections referenced in the non-powered testing sections using a torque screwdriver that is
calibrated in pound-force inches or Newton meters. 

5.3

Connection Polarity Test

To verify that the input power wires are connected to the correct terminals, apply power to the
panel. Using a multimeter, measure the voltage between the input return connector (RTN) and
the chassis ground. The voltage should be less than 2.0 Vdc. If the voltage is more than 2.0 Vdc,
reverse the input power wires and measure the voltage between the input return connector
(RTN) and the chassis ground again to verify that the voltage is less than 2.0 Vdc. 

5.4

Alarm Contact Test

Following application of power, test the operation of the alarm relay contacts. With all circuit
breakers closed, the alarm relay terminals should provide an open circuit between the common (C)
terminal and the normally open (NO) terminal and a closed circuit between the C terminal and the
normally closed (NC) terminal. 

5.5

Circuit Breaker Alarm Test

Place a circuit breaker switch on each bus in the “OFF” position (bottom pushed in). The visual
circuit breaker alarm indicator (LED) for the bus will change from unlighted to a red light, and the
circuit breaker failure alarm relay will operate. Reset the circuit breakers.

OPERATION

Caution: 

Before performing this test, verify that the input and output power is not connected to

the circuit breaker panel connectors.

Caution: 

This equipment employs electrical voltage and amperage levels which may be

considered an electrical hazard. Care should be exercised to assure that only qualified
personnel are allowed to install, operate, maintain, or otherwise come in contact with the
circuit breaker panel when it is energized. Only insulated tools should be used on energized
elements of the panel.
