3. Output Testing

! ALERT

ALERT! This product must be installed and maintained only by qualified personnel. Verify all connections meet requirements specified in local electric codes or operating company guidelines before supplying power. Protect this equipment with a fuse or breaker sufficient to interrupt power levels specified in Section 1 of this manual.

1.For initial startup, make sure all BDFB / BDCBB circuit break- ers and all inputs at output loads are disabled (disconnected or off).

2.With Feed A and B to panel turned on —

•Verify that VDC PWR lamps turn green.

•Verify that FUSE ALM lamps turn red.

NOTE

The FUSE ALM lamp will light if any circuit breaker on the corresponding bus is off.

3.Use a DVM with standard .080-in. test probes to re-verify power at panel’s VDC test points for Feed A:

•Connect panel RED (-48Vdc) to meter RED (voltage).

•Connect panel BLK (RTN) to meter BLK (common).

4.Use an ohmmeter at alarm monitor to verify alarm conditions for each feed.

With input feed OK, but with any circuit breaker OFF, expect the following feed conditions:

•For the power alarm circuit, expect either continuity (0 Ω) between C and NC poles or an open circuit (∞ Ω) between C and NO.

•For the circuit breaker (fuse) alarm circuit, expect either an open circuit (∞ Ω) between C and NC poles or conti- nuity (0 Ω) between and C and NO.

5.Make sure power is disabled at the first load and then turn on the corresponding BDFB / BDCBB circuit breaker.

6.Use a DVM to test power and polarity at input terminals of load.

7.Turn on the corresponding load and verify proper load opera- tion.
