Step 6: Performing Checks Prior to Initial Start-Up

Before testing your installation, ensure these conditions are met.

❐ AC earth are properly installed.

❐ AC input connections and AC output connections are wired correctly on the

terminal block and not reversed.

❐ Positive (+) battery cable is connected to the positive (+) battery terminal

through the DC fuse and disconnect switch or DC circuit breaker.

❐ Negative (–) battery cable is connected to the negative (–) battery terminal.

❐ Battery voltage is within the proper range for this unit: 21–33 VDC.

❐ DC disconnect switch or breaker is turned off.

❐ AC input and output breakers are turned off.

❐ All connections are tight.

Step 7: Testing Your Installation

There are several tests to be performed for testing your installation. These tests

will verify that:

• The Conext SW works in invert mode.

• The Conext SW works in charge mode.

• The Conext SW works in AC bypass mode.

If the test fails at any point, go to “Step 6: Performing Checks Prior to Initial Start-

Up” on page 1–27 and go through the checklist again to check the installation.

Then perform the test again. If the test fails again, see the troubleshooting

section in the Conext SW Inverter/Charger Owner’s Guide.

WARNING

ELECTRICAL SHOCK HAZARD

The Inv Enable button on the Conext SW front panel and the SCP do not

disconnect DC or AC input power to the Conext SW. Isolate energy by turning

off and locking out all AC and DC circuit breakers and test with a multimeter

before checking or tightening electrical connections.

Failure to follow these instructions can result in death or serious injury.
