Outback FX-R Series Installation Manual

900-0166-01-01 Rev A 15
Installation
Location and Environmental Requirements
FXR and VFXR series inverter/chargers must be located indoors or in a weather-proof enclosure.
They are not designed for exposure to water, salt air, or excessive wind-blown dust and debris.

The inverter can often be mounted in any position or orientation. When inverters are installed with an
OutBack FLEXpower system, the system must be installed in the upright orientation due to the
requirements of the circuit breakers.

These inverters will perform more efficiently in locations offering plenty of air circulation. The minimum
recommended clearance is 2 inches (5 cm) on all sides of the inverter.

These inverters will operate normally in a range of –4°F to 122°F (–20°C to 50°C). Maximum output will
begin to decline at ambient temperatures above 25°F (77°C).

The allowable temperature range for storage is –40°F to 140°F (–40°C to 60°C).

These inverters carry an Ingress Protection (IP) rating of 20 and a Relative Humidity (RH) rating of 93%
(non-condensing).

Inverter specifications are listed in the FXR Series Inverter/Charger Operator’s Manual.
Tools Required
The following tools may be required for this installation:

Wrench and socket sets; should include
~ torque and ratchet wrenches

Wire cutters/strippers
Mounting

One person can install the FXR inverter, but installation may be easier with two people.

The unit has four mounting holes, one in each corner. Use fasteners in all corners.

Due to the variance in other mounting methods, OutBack only endorses the use of FLEXware mounting
products. Use M6 x 20 mm machine screws, one per corner, to attach the inverter to the mounting plate.
Follow the instructions with each mounting system.

Mount the plate on a flat, solid mounting surface. Ensure the surface is strong enough to handle three
times the total weight of all the components. If using a FLEXware Mounting Plate, avoid large air gaps
behind the plate. These can result in louder mechanical noise during heavy inverting or charging.

Mount and secure each component before attaching any wiring.

When the inverter is used with other metal chassis, make sure that all chassis are grounded
appropriately. (See the grounding instructions on page 18.) Grounding other chassis may involve
metal-to-metal contact, or separate ground wires.
IMPORTANT:
Use correct fasteners to secure the inverter to the mounting surface, regardless of the
type of surface. OutBack cannot be responsible for damage to the product if it is attached
with inadequate fasteners.

Insulated screwdriver set (flat and Phillips)

Long-nose pliers

