[ ] 6. For kit P/N 60056702, install a kit supplied 75 A circuit breaker in the power system’s -48 VDC distribution bus (typically
position 5, in Row 2 (top) of the distribution cabinet for the 582137100ZZ028 and 582137100500).
For kit P/N 60051981, install a kit supplied 75 A circuit breaker in the power system’s -48 VDC distribution bus (typically
position 5, in Row 2 (top) of the distribution cabinet for the 582137100ZZ028 and 582137100500) and the remaining kit
supplied 75 A circuit breaker in the power system’s -58 VDC distribution bus (typically position 18, in Row 2 (top) of the
distribution cabinet for the 582137100500).
Take the following into considerations when choosing a circuit breaker mounting location: SPD location and the need to
minimize SPD power cable lengths.
[ ] 7. Connect the alarm jumpers provided in the P/N 60056635 alarm jumper kit supplied with the SPD kit as shown in Figure
3.34.
a) Connect the SPD alarm contacts in series using the kit supplied blue alarm jumpers as shown in Figure 3.34.
Recommended strip length is 0.25”. Recommended torque is 2.2 in-lbs.
b) Connect SPD alarm contact terminal 11 of the last SPD to that SPD’s “+” terminal as shown in Figure 3.34. Assemble
blue alarm jumper with #10 spade lug to SPD “+” terminal slot (under the screw head). Terminal screw will be
tightened later in the procedure after the black “+” 6 AWG wire is installed to the same terminal.
c) Jumper terminals J5-1 (DI7-) to J5-3 (DI8-) of the power system’s IB2 controller interface board using the kit
supplied red alarm jumper as shown in Figure 3.34. Recommended torque is 2.2 in-lbs.
[ ] 8. Connect SPD alarm contact terminal 12 of the first SPD to the power system’s IB2 controller interface board using the kit
supplied alarm cable (P59888A) as shown in Figure 3.34.
a) Trim cable insulation by 1.25” from cable end and discard insulation. Keeping the blue/white wire, trim back the
other three wires and discard.
b) Strip the blue/white wire by 0.25”.
c) Assemble blue/white wire to SPD alarm terminal 12. Recommended torque is 2.2 in-lbs.
d) Route cable to IB2 board in the power system distribution unit. Cut the cable as required in order to reach IB2 DI7+
(IB2 terminal J5-2).
e) Trim cable insulation by 1.25” from cable end and discard insulation. Keeping the blue/white wire, trim back the
other three wires and discard.
f) Strip the blue/white wire by 0.25”.
g) Assemble blue/white wire to IB2 DI7+ (IB2 terminal J5-2). Recommended torque is 2.2 in-lbs.
