3.3 Materials 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 8)
• Ring or 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
3.4 Continuity 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.
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.
TEST 1- POWER BUS A:
VERIFY NO CONTINUITY
EXISTS BETWEEN BATT
AND RTN TERMINALS
TEST 1- POWER BUS B:
VERIFY NO CONTINUITY
EXISTS BETWEEN BATT
AND RTN TERMINALS
