Functional Test

WARNING: Shock Hazard and Equipment Damage

It is necessary to remove the inverter cover to perform these tests. The components are close together and

carry hazardous voltages. Use appropriate care to avoid the risk of electric shock or equipment damage.

Pre-startup Procedures

1. Ensure all DC and AC overcurrent devices are opened, disconnected, or turned off.

2. Double-check all wiring connections.

3. Confirm that the total load does not exceed the inverter’s wattage. (See page 22.)

4. Inspect the work area to ensure tools or debris have not been left inside.

5. Using a digital voltmeter (DVM) or standard voltmeter, verify battery voltage. Confirm the

voltage is correct for the inverter model. Confirm the polarity.

6. Connect the MATE3 system display, if present.

Startup

It is highly recommended that all applicable steps be performed in the following order. However, if

steps are inapplicable, they can be omitted.

If the results of any step do not match the description, see the Troubleshooting section on page 50.

To start a single-inverter system:

1. Close the main DC circuit breakers (or connect the fuses) from the battery bank to the inverter.

Confirm that the system display is operational, if present.

2. If a system display is present, perform all programming for all functions.

These functions may include AC input modes, AC output voltage, input current limits, battery

charging, generator starting, and others.

AC input modes are described beginning on page 13 and are summarized on page 21. The

inverter’s individual operations are described beginning on page 22.

3. Turn on the inverter using the MATE3 or external switch. The Radian’s default condition is Off.

Do not turn on any AC circuit breakers at this time.

CAUTION: Equipment Damage

Incorrect battery polarity will damage the inverter. Excessive battery voltage also may damage the inverter.

This damage is not covered by the warranty.

IMPORTANT:

Prior to programming (see Startup), verify the operating frequency of the AC source. This is necessary for

correct AC operation. The default setting is 50 Hz, but this can be changed to 60 Hz.
