Wiring a standalone PowerMaxx2

1.
Remove the fuses from the spurs that will power the pumps being used with the PowerMaxx2.
2.
Ensure the power switch of the PowerMaxx2 is in the OFF position.
3.
Remove the PowerMaxx2 lid and side panels from the unit.
4.
If you are configuring the unit with one pump, fit two large cable glands into the primary side of the unit
and two blanking plugs into the secondary side of the unit.
If you are configuring the unit with two pumps, fit two large cable glands into the primary side of the unit
and two large cable glands into the secondary side of the unit.
If you are connecting an AlertMaxx2, fit a small cable gland into the small hole above the secondary holes.
5.
Using the cable glands on the back of the PowerMaxx2, feed the power and pump cables through and to
the correct terminal blocks on the lower circuit board.
There are two connector blocks on the lower circuit board: PRIMARY and SECONDARY. The primary
connector block should always have a connection, as this is the supply that charges the PowerMaxx2.
6.
Connect the supply to the "From Mains" and the corresponding pump to the "To Pump" (figure 2).
7.
Connect the battery pack by plugging in the grey Anderson connector.
