2.14 Installation Checklist
Use this checklist as a fi nal review to ensure all essential steps to install the MMP enclosure have
been completed before proceeding with the functional test.
Mounting
The MMP enclosure/inverter system is securely mounted in a clean, dry, and ventilated area.
The system is not mounted in the same enclosure as maintenance-free or vented type batteries.
The MMP enclosure is mounted in a ‘vertical only’ position.
There is adequate clearance to access the front and to view/adjust the remote (if installed).
DC Wiring (use Table 2-4 to determine the DC wire size).
Inverter Side with Magnum Inverter (see Figure 1-2, Items 9A & 10A):
The inverter is correctly placed onto the MMP enclosure with the inverter’s DC terminals attached
to the tops of the DC negative busbar and the DC positive busbar inside the MMP enclosure.
Inverter Side without Magnum Inverter (see Figure 1-2, Items 9B & 10B):
An appropriately sized DC cable is routed and attached from the inverter’s DC positive (+)
terminal to the DC positive connection at the top of the DC breaker inside the MMP enclosure.
An appropriately sized DC cable is routed and attached from the inverter’s DC negative (–)
terminal to the DC negative connection at the top of the DC shunt inside the MMP enclosure.
Battery Bank Side (see Figure 2-8):
An appropriately sized DC cable is routed and attached from the positive (+) battery terminal
to the bottom battery bank connection of the DC disconnect breaker inside the MMP enclosure.
An appropriately sized DC cable is routed and attached from the negative (–) battery terminal
to the bottom battery bank connection of the DC shunt inside the MMP enclosure.
The DC cable connections and DC hardware are stacked (Figure 2-9) and torqued (Tables 2-1
to 2-3) correctly.
AC Wiring (use Table 2-5 to determine the AC wiring confi guration and to fi nd the AC wire size).
In and Out of Inverter (see Figures 2-10 & 2-11):
The AC wires are appropriately sized and routed from the INVERTER AC TERMINAL BLOCK
(inside MMP enclosure) to the inverter’s AC input/output terminals.
To Main AC Electrical Panel (see Figures 2-12 to 2-15):
The AC wires are appropriately sized and are routed from the grid/gen side of the EXTERNAL
AC TERMINAL BLOCK (inside MMP enclosure) to the circuit breaker in the main AC electrical panel
powered by the utility or generator (i.e., main panel).
To Inverter AC Load Panel (see Figures 2-12 to 2-15):
The AC wires are appropriately sized and are routed from the AC load side of the EXTERNAL
AC TERMINAL BLOCK (inside MMP enclosure) to the main circuit breaker in the electrical panel
powered by the inverter (i.e., sub-panel).
The AC wires connected to the terminal blocks are torqued correctly (see Tables 2-1 to 2-3).
Grounding
There is only one bonding connection to ground for the DC electrical system (negative to ground)
and one bonding connection to ground for the AC electrical system (neutral to ground). These
bonding connections may be connected to the same grounding electrode system (ground rod). If
separate electrodes are used, they must be bonded together.
The exposed metal parts of equipment are properly grounded.
Equipment grounding conductors are properly sized.
Electrical Connections
Connectors are listed for the intended use and environment (inside, outside, wet, etc.,).
Pressure/screw terminals tightened to the recommended torque specifi cation.
Terminals containing more than one conductor are listed for multiple conductors.
Connectors using fl exible, fi ne-stranded conductors are listed for use with such conductors.
Re-torque electrical terminal connections in the inverter that may have loosened.
