Installation
Step 10: Performing Checks Prior to Initial Start-up
Before starting up your inverter, ensure these conditions are met:
❐Chassis ground is properly installed
❐On/Standby switch is in the Standby ( 
) position on the TS400
❐Positive (+) battery cable is connected to the positive (+) battery terminal through the DC fuse and Disconnect or DC circuit breaker
❐Negative
❐Battery voltage is within the proper range for this unit
❐DC Fuse is intact (not blown)
Step 11: Testing Your Installation
WARNING: Shock hazard
The On/Standby switch on the TS400 does not disconnect DC power to the TS400.
When you are ready to test your installation and operate the TS400, close the DC fuse and Disconnect or the DC circuit breaker to supply DC power to the TS400.
To test the TS400:
1.Turn the inverter’s On/Standby switch to the On ( 
) position. If the optional S400 Remote Switch is installed, turn the On/Standby switch on the remote switch to the On ( 
) position.
The green Inverter ON indicator illuminates.
2.Plug an appliance of 400 watts or less into one of the GFCI outlets.
3.Turn the appliance on to verify that it operates.
4.If the appliance operates, your installation is successful.
5.If the red Fault light illuminates, see “Troubleshooting” on page
