3.3Materials Required

The following materials are required to install the fuse platform:

•#2 AWG insulated copper wire for input power wires

•2-hole compression lugs for #2 AWG wire (0.625 inches between centers)

•#10 AWG copper wire for ground connections

•Insulated copper wire for fused output power wires (refer to Table 1 on page 9)

•Spade-type connectors for output power wires

•#16 to #30 AWG insulated copper wire for alarm terminal screw-down barrier terminal strip connectors (if present)

•#22 to #26 AWG insulated copper wire for alarm terminal wire-wrap pins (if present)

•Heat-shrink tubing

3.4Continuity Tests

Each panel is thoroughly tested at the ADC factory before being shipped. However, before the panel is installed, continuity tests, as described here, should be performed to verify that no internal damage has occurred during shipping and handling.

Using a multimeter that is set to perform a continuity check, perform the following tests.

Test 1: Input Battery to Input Return—Perform this test on each input power terminal block. Connect one test probe to the input power BATT (–) terminal and the other test probe to the input power RTN (+) terminal. Verify that no continuity exists between the input power BATT and RTN terminals. Figure 7 shows test points on dual bus fuse platform with A and B input power terminal blocks.

TEST 1- POWER BUS B: VERIFY NO CONTINUITY EXISTS BETWEEN BATT AND RTN TERMINALS

TEST 1- POWER BUS A: VERIFY NO CONTINUITY EXISTS BETWEEN BATT AND RTN TERMINALS

18871-A

Figure 7. Test 1: Input Battery to Input Return

Test 2: Input Battery to Output Battery—Perform this test for each fuse position and fuse type (refer to Figure 8 and Figure 9).

1.Remove the fuse holder from the fuse platform.

2.Insert a working fuse into the fuse holder.
