Step 9: Testing Your Installation
There are several tests to be performed for testing your installation. These tests
will verify that:
• The MS2000 works in invert mode.
• The MS2000 works in charge mode.
• The MS2000 works in AC bypass mode.
• The Echo Charger is functioning.
Testing in Invert Mode
To test the inverter/charger in invert mode, using a 100 watt light bulb as the
test load:
1. Close the DC disconnect switch or the DC circuit breaker to supply DC power
to the MS2000.
The unit takes 10 to 30 seconds to initialize.
2. Verify that all lights on the front panel illuminate during the initialization
stage. If other Xanbus-enabled devices are connected, the Network light will
be illuminated. The Invert light illuminates only if the Invert Enable button
light is also illuminated. If the unit is powered up for the first time, the
Inverter On light will be off. To turn the inverter on, press the Invert Enable
button.
3. Connect the MS2000 to the test light by closing the AC breaker that contols
the circuit that the test light is connected to.
If the light bulb illuminates, the installation has been successful.
Testing in Charge Mode
To test the MS2000 in charge mode:
1. Close the AC supply breaker to supply AC power to the unit.
2. After a few seconds, verify that the External AC and Charger ON lights on the
front panel illuminate. One of the current range lights (>75A, 25–75A,
10–25A, >10A) should also illuminate.
WARNING: Shock hazard
The Inverter Enable button on the MS2000 and the optional accessories do not disconnect
DC or AC input power to the MS2000.
Important:
The charging process, whether it is three-stage or two-stage charging,
occurs over an extended period of time.
