SECTION 9 | 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 Con-
trol from Remote location using 2-Wire or 1-Wire External ON/OFF Control" on page 38.
!
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.
