WARNING: Shock Hazard and Equipment Damage
The inverter cover must be removed 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.
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 Operator’s Manual for troubleshooting.
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.
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 system display, if present.
Startup
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.
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.
