Operation
9.1 SWITCHING THE INVERTER ON/OFF
Before switching on the inverter, check that all the AC loads have been switched off.
The 3-Position Rocker Switch marked ON/OFF/EXT. Switch (1, fig 6.1a) on the front
panel of the inverter is used to switch ON and switch OFF the inverter. This switch
operates a low power control circuitry, which in turn controls all the high power
circuitry.
The unit can also be switched ON/OFF remotely as follows:
• Through optional Remote Control Model RC-300 connected to Modular Jack RJ-50
(9, fig 6.1a). Read Optional Remote Control Manual for RC-300 for details.
• Using 2-wire or 1-wire External Switching Control. See details under heading
“ON/OFF Control from Remote location using 2-Wire or 1-Wire External ON/OFF
Control”.
CAUTION!
Please note that the ON/OFF switch is not switching the high power battery
!
input circuit. Parts of the DC side circuit will still be alive even when the
switch is in the OFF position. Hence, disconnect the DC and AC sides before
working on any circuits connected to the inverter.
When the inverter is switched ON, the Green LED marked “POWER” (2, Fig 6.1a)
will be lighted. This LED indicates that the input section of the inverter is operating
normally. Under normal operating conditions, AC output voltage will now be
available at AC Socket and at the AC output terminals for hardwiring (13, Fig 6.1b).
Switch on the AC load(s). The Green LED marked “POWER” (2, Fig 6.1a) normal
operation of the load.
