Mounting Multiple Inverters in Parallel
As shown in Figure 2-10, inverters can be mounted side by side on wallboard or a
plywood support. A minimum of 30 cm (12 inches) of clearance between the units
is recommended.
Conduit nipples should be installed on one side of the first inverter before
mounting on the bracket. Ensure that the sealing ring is located on the conduit
nipple between inverters, i.e., on the outside of the wiring box. The lock nut is
attached after the nipple is inserted into the conduit hole of the second inverter
Installing Accessories
The optional fan assembly and heat sink cover (see Figure 1-5 on page 1–7)
should be installed together. Neither accessory should be installed without the
other.
Installing the Fan Assembly
The fan assembly (see Figure 1-5 on page 1–7) is optional for the GT Inverter.
Installing the fan assembly involves two main steps:
1. Attaching the fan assembly to the inverter.
2. Connecting the fan wires.
WARNING: Shock hazard
If the inverter is already installed and operational, turn OFF the breaker switches in the
main utility service panel and the AC/DC Disconnect switch on the inverter wiring box
before performing this procedure.
WARNING: Shock hazard
Hazardous voltages may be present when cover is removed. After disconnecting all
sources of energy, wait 5 minutes before removing cover.
WARNING: Burn hazard
Ensure that the inverter and heat sink are not too hot to touch before attempting this
procedure.
Important:
The fan assembly should only be installed by qualified personnel.
