3.12 Installation Checklist
Use this checklist as a fi nal review to ensure all essential steps of the MP enclosures installation
have been completed before proceeding with the functional test.
Mounting
❐ The MP enclosure/inverter system is securely mounted in a clean, dry, and ventilated area.
❐ The MP enclosure/inverter system is not mounted in the same enclosure as maintenance-free
or vented type batteries.
❐ The MP 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
Inverter Side:
❐ The inverter is correctly placed on the MP enclosure with the inverter’s DC terminals attached
to the inverter DC negative and positive cables inside the MP enclosure.
Battery Bank Side:
❐ An appropriately sized DC cable is routed from the positive (+) battery terminal and attached
to the bottom terminal of the inverter DC disconnect breaker inside the MP enclosure.
❐ An appropriately sized DC cable is routed from the negative (-) battery terminal and attached
to the busbar which is connected to the bottom terminal of the DC shunt inside the MP enclosure.
❐ The DC hardware is stacked correctly (refer to Figure 3-20).
❐ The DC cable connections are torqued correctly (refer to Tables 3-1 to 3-3).
AC Wiring
❐ To Inverter: The AC wires are appropriately sized and routed from the inverter AC Input breaker(s)
inside MP enclosure to the inverter’s AC input terminals.
❐ From Inverter: The AC wires are appropriately sized and routed from the inverter’s AC output
terminals to the AC output busbars (INV HOT 1 OUT, INV HOT 2 OUT, AC NEUTRAL and GROUND)
inside MP enclosure.
❐ To Main AC Electrical Panel: The AC wires are appropriately sized and are routed from the AC
input busbars (AC LEG 1 IN, AC LEG 2 IN, AC NEUTRAL and GROUND) inside MP enclosure to the
circuit breaker in the main AC electrical panel (i.e., main panel) powered by the generator or grid.
Use Table 3-4 to determine the AC wire size to/from the MP enclosure.
❐ To Inverter AC Load Panel: The AC wires are appropriately sized and routed from the AC output
busbars (AC LEG 1 OUT, AC LEG 2 OUT, AC NEUTRAL and GROUND) inside MP enclosure to the
main circuit breaker in the electrical panel powered by the inverter (i.e., sub-panel). Use Table
3-4 to determine the AC wire size to/from the MP enclosure.
❐ AC wires connected to the busbars/circuit breakers are torqued correctly (see Tables 3-1 to 3-3).
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.
❐ All electrical terminal connections in the inverter are re-torqued to tighten any connections that
may have loosened since the initial installation.
