8.6 GROUNDING TO EARTH OR TO OTHER DESIGNATED GROUND
For safety, ground the metal chassis of the inverter to the Earth Ground or to the other

designated as the Negative DC Ground). A chassis Grounding Lug (19, Fig 6.1c) has been
provided for grounding the metal chassis of the inverter to the appropriate ground.
When using the inverter in a building, connect a 10 mm

that connects to the Ground Rod or to buried metallic water pipe or to another connection
that is solidly bonded to the Earth Ground ). The connections must be tight against bare

to penetrate paint and corrosion.
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.
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
