3.14 Installation Checklist
Use this checklist as a fi nal review to ensure all essential steps to install the MMP enclosure have
been made before proceeding with the functional test.
Mounting
 The MMP enclosure/inverter system is securely mounted in a clean, dry, and ventilated area.
 The MMP enclosure/inverter system is not mounted in the same enclosure as maintenance-free
or vented type vented 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 3-4 to determine the DC wire size).
Inverter Side with Magnum Inverter:
 The inverter is correctly placed on the MMP enclosure with the inverter’s DC terminals attached
onto the inverter DC Negative and Positive Busbars inside the MMP enclosure.
Inverter Side without Magnum Inverter:
 An appropriately sized DC cable is routed from the inverter’s DC positive (+) terminal and
attached to the top terminal of the Inverter DC disconnect inside the MMP enclosure.
 An appropriately sized DC cable is routed from the inverter’s DC negative (-) terminal and
attached to the top terminal of the DC Shunt inside the MMP 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 inside the MMP enclosure.
 An appropriately sized DC cable is routed from the negative (-) battery terminal and attached
to the bottom terminal of the DC Shunt inside the MMP enclosure.
 The DC cable connections and DC hardware is stacked (Figure 3-10 or 3-11) and torqued (Tables
3-1 to 3-3) correctly.
AC Wiring (use Table 3-5 to determine the AC wiring confi guration and to fi nd the AC wire size).
 In and Out of Inverter: The AC wires are appropriately sized and routed from the INVERTER AC
IN/OUT TERMINAL BLOCK (inside MMP enclosure) to the inverter’s AC input/output terminals.
 To Main AC Electrical Panel: The AC wires are appropriately sized and are routed from the Grid/
Gen side of the EXTERNAL AC IN/OUT 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: The AC wires are appropriately sized and routed from the AC Load
side of the EXTERNAL AC IN/OUT 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 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.
 Re-torque all electrical terminal connections in the inverter to tighten any connections that
may have loosened since the initial installation.
