Installation

 

In this chapter only the first step, mounting the inverter and installing accessories,

 

is described.

Mounting steps

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

 

• “Installing Accessories” on page 2–23.

Multiple inverter

Mounting instructions for multiple inverters connected in parallel are described in

instructions

“Mounting Multiple Inverters in Parallel” on page 2–23.

 

Special wiring instructions for multiple inverters connected in parallel are

 

described in “Connecting Inverters in Parallel” on page 3–10.

Preparing to Mount the Unit

Dimensions and Knockout Locations

The dimensions of the inverter and the mounting bracket and some of the knockout locations on the wiring box are shown in Figure 2-7.

Four 2 cm or 2.5 cm (3/4 inch or 1 inch) knockouts are provided on the back and bottom of the unit to accommodate wiring:

two on the bottom of the wiring box, on either side of the AC/DC Disconnect Switch

two on the back of the wiring box.

Four 2 cm (3/4 inch) conduit holes on the sides of the wiring box are filled with plastic plugs, which can be removed to insert conduit nipples as required for inverters mounted in parallel. One or two of these side conduit holes may be used to accommodate communications wiring for multiple inverters mounted in parallel.

Knockout Preparation

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 in the inverter after removing the knockouts. Be sure to install bushings or conduits in the knockout holes to protect the wires from damage.

If installed outdoors, conduit must be sealed where it enters the wiring box.
