Installation
2.8 Final Inspection
1. Verify all cable runs are secured with wire ties or other non-conductive fasteners to prevent
chafi ng, or damage from movement and vibration.
2. Verify strain reliefs or grommets are in place to prevent damage to the wiring where it passes
through walls, bulkheads, or other openings.
3. Verify all AC connections are correct and torqued to a maximum of 16 in lbf (1.8 N-m).
4. Replace the covers on the main electrical/distribution panel.
5. Replace the chassis access cover.
6. Verify the inverter’s front panel switch is in the OFF position.
Info: If required by code, have the installation inspected by an electrical inspector.
2.9 Functional Test
After all electrical connections to the inverter, batteries, AC source, and sub-panel have been
completed, follow these steps to test the installation and the inverter operation.
CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter
model (i.e., 12-volt battery bank for a 12-volt inverter), and to ensure the polarity of the
battery voltage is correct (battery positive connected to inverter positive, and battery
negative connected to inverter negative).
1. Apply battery power to the inverter by closing the DC circuit breaker or inserting a fuse. The
inverter will remain OFF, but the green status indicator on the front of the inverter will quickly
blink once to indicate that DC power has been connected and is ready to be turned on.
2. Prior to turning on the inverter, make sure all AC loads (e.g., appliances) are NOT connected
to the inverter’s output or any AC outlets powered by the inverter.
3. Lightly press and release the inverter’s ON/OFF switch to turn the inverter ON. Verify the
inverter’s status indicator is blinking—indicating the inverter is ON.
4. Connect a small light bulb no larger than 75 watts to the inverter output and verify it comes on
and shines normally. DO NOT connect anything but a light bulb until all wiring and voltages are
confi rmed to be correct.
Info: The inverter’s AC output voltage will not be correct until a load greater than
5 watts (5 watts is the default setting) is connected to the inverter; or, when the
Search mode is turned OFF with a remote display (ME-RC50).
5. Check the AC output voltage of the inverter by connecting an AC voltmeter to the output
terminals (see Figure 2-20) and verify the correct output voltages.
Info: For the ME2000 models, remove the fi eld wiring leads in order to get a good
connection and reading with the AC voltmeter (see Figures 2-21 and 2-22). For the
ME2000-15/-20 models you must check the HOT1 OUT and HOT2 OUT wires in Single
In - Dual Out confi gurations.
6. Press and release the inverter’s ON/OFF switch to turn the inverter off. The inverter’s status
indicator and the connected load should go off.
7. Apply AC power to the inverter’s AC input. After the AC input power is qualifi ed (approx. 15 secs),
the incoming AC power transfers through the inverter to the inverter’s AC output and powers
the light bulb. Verify that the inverter’s status indicator and the light bulb come on.
8. Even though the light bulb is on, the inverter is currently disabled (off). Press and release the
ON/OFF switch on the inverter to enable (turn-on) the inverter.
9. Disconnect the incoming AC power to the inverter. Verify the light bulb remains on and is now
powered by the inverter.
If the inverter passes all the previous steps, the inverter is ready for use. If the inverter fails any
of the steps, refer to the Troubleshooting section.
