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 ground (for example, in a mobile RV, the metal frame of the RV
is normally 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 2.5 mm
2
insulatedstranded copper
wire from the above equipment grounding lug to the Earth Ground connection
(a connection 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 metal. Use star washers to penetrate paint and corrosion.
When using the inverter in a mobile RV, connect a 2.5 mm
2
insulatedstranded copper
wire from the above Chassis Grounding Lug to the Main Grounding Bus Bar of the
RV (bonded to the vehicle chassis). The connections must be tight against bare metal.
Use star washers to penetrate paint and corrosion.
8.7 OPTIONAL WIRED REMOTE CONTROL – MODEL RC-300
CAUTION!
For the optional remote Control RC-300 to operate, the inverter has to be
!
FIRST turned ON using the following ON / OFF controls:
a)
When NOT using external 1-Wire or 2-Wire ON / OFF Control: By pushing
the top end (marked “–”) of the 3-Position Rocker Switch (1, fig 6.1a) to
position marked “ON”
b)
When using external 1-Wire or 2-Wire ON / OFF Controls: By FIRST
pushing the bottom end (marked “=”) of the 3-Position Rocker Switch
(1, fig 6.1a) to position marked “EXT. Switch” and THEN switching ON
the inverter by (i) closing the switch or relay contact in 2-Wire ON/OFF
Control (fig 8.2a) or (ii) closing the switch or relay contact in 2-Wire ON/
OFF Control using switched DC voltage (fig 8.2b) or (iii) closin the switch
or relay contact in 1-Wire ON/OFF control using switched DC voltage
from battery supplying the inverter.
An optional Wired Remote Control Model No. RC-300 (with 25 ft. / 7.62 metre cable),
is available for switching ON and switching OFF and monitoring. The remote has
LCD display showing AC output V, A, Hz, W, VA and Power Factor. It also has LED
indications similar to the indications on the front panel (2, 3, 4 in fig. 6.1a). The
Remote Control is connected to RJ-50 Jack (9, fig 6.1a). Read Remote Control Manual
for details.
