Step 2 - Select cable size
Select the required dc output cable size from the following table, according
to each circuit breaker rating:
Circuit breaker rating Maximum load current
Cable size*
6A
4.8A
10A 8A
15A 12A
14AWG / 1.5mm
2
20A
16A
12AWG / 2.5mm
2
25A 20A
30A 24A
10AWG / 4mm

* These cable sizes are calculated to limit the voltage drop to 1.0V or less at
the maximum current for a distance of up to 12feet / 3.6m from the
EPS2/EPS5 to the load equipment. For greater distances increase the cable
size.
Step 3 - Connect dc output cables
1
Route the cables to the rear of the EPS2/EPS5.
2
Connect the first positive cable to the LOAD COMMON terminal 1.
3
Connect the first negative cable to the LOAD -VE terminal 1
(connected to load circuit breaker 1).
4
Repeat for all other cables.
5
Tighten all terminals to 9 in-lb / 1Nm.

Step 4 - Check terminations, secure cables and test insulation
1
Check all terminations are correct and are tightened.
2
Secure the cables with cable ties to ensure there will be no strain on the
terminals.
3
Test the insulation resistance of the cables.
