In this chapter only the first step, mounting the inverter and installing accessories,
is described.
Instructions for mounting the GT Inverter are described in the following sections:
• "Preparing to Mount the Unit" on page 2–16
• "Installing the Mounting Bracket" on page 2–17
• "Mounting the Inverter on the Bracket" on page 2–22.
Mounting instructions for multiple inverters are described in "Mounting Multiple
Inverters" on page 2–23.
Special wiring instructions for multiple inverter installations are described in
"Connecting Multiple Inverters" on page 3–9.
The dimensions of the inverter and the mounting bracket and some of the
knockout locations on the wiring/disconnect box are shown in Figure 2-7.
Four 27 or 35 mm (1 or 1 3/8 inch) dual knockouts are provided on the back and
bottom of the unit to accommodate wiring:
• two on the bottom, on either side of the DC/AC Disconnect Switch
• two on the back of the wiring/disconnect box.
Four 27 mm (1 inch) conduit holes on the sides of the wiring/disconnect box (two
on each side) are filled with plastic plugs, which can be removed to insert conduit
nipples as required for multiple inverter installations. One or two of these side
conduit holes may be used to accommodate Xanbus network cables connected
between multiple inverters.
CAUTION: Equipment damage
If your installation location requires that you drill additional conduit holes into the
wiring/disconnect box, ensure that there are no metal shavings left inside the unit. These
could cause a short circuit when the unit is operating.
Remove your choice of knockouts from the wiring box to facilitate conduit
installation for wire runs. This is much easier to do prior to mounting the inverter.
Important:
Ensure there are no metal shavings left inside the unit after removing the
knockouts. These could cause a short circuit when the unit is operating. Be sure to install
bushings or conduits in the knockout holes to protect the wires from damage.
Important:
If installed outdoors, conduit must be sealed where it enters the wiring box.
