RiSK oF eLectRic SHocK. When this unit is installed in vehicles and hard-wiring
connection is used to feed the AC output of the inverter to the AC Panel-
board / Load Center in the vehicle, it is to be ensured that Ground fault Circuit
Interrupter(s) [GfCI] are installed in the vehicle wiring system to protect all
branch Circuits.
The GfCIs in Table 8.3 have been tested to operate satisfactorily and are accept-
able. other types may fail to operate properly when connected to this inverter:

Mfr. of GFci Mfr.’s Model no. Description
Pass & Seymour 2095 Series NEMA5-20 Duplex 20A

8.5.3 Hard Wiring of Ac output – Sizing of Wiring and Breaker
Sizes of Line and Neutral conductors and breaker are shown in Table 8.4. Sizing is based on
safety considerations specified in UL-458 and NEC-2014. Please refer to “Notes for Table 8.4”
for details.
example of Ac cable types: (a) 12/3, Loomex / Romex (NMD-90) - non Metallic sheathed;
Dry: 90°c. This is a 3-conductor (Insulated Line, Neutral and bare Ground), AWG #12 cable
used for residential wiring (b) AC cord types: SE, SEoo, ST, STo, SJ, SJEoo, SJT or SJTo
for firm connection when using set screw type of terminals for connecting stranded wire,
use “Cord End Terminals” for termination of the bare Line and Neutral ends of the conduc-
tors and “Ring Type of Terminal” for termination of the bare end of Grounding Conductor.
for convenience, the following terminals have been provided:
For Line and neutral conductors: 2 pieces of Cord End Terminals for conductor size AWG#12
For neutral conductor: 1 piece of Ring Terminal for #6 stud and for conductor size AWG#12

cAUtion!
(a) Use proper Crimping Tool to crimp the terminals to the bare ends of the conductors.
(b) Make sure that the AC cable is adequately clamped by the metal Strain Relief
Clamp (7, fig 6.1a)

1. Please ensure correct polarity of wiring connection. Positive (+) of the external DC
source should be connected to Terminal 3 of the Terminal Block (10, fig 6.1a) and
Negative (-) to Terminal 4. In case the polarity is reversed, the oN/off control will
not operate. the input to these terminals is protected against reverse polarity
2. Use 1A fuse as shown as close to the DC source as possible

The 10-33VDC external control signal on terminals 3 and 4 of the Terminal Block
(10, fig 6.1a) feeds to an internal opto-Isolator. Hence, the Negative Ground of the
external 10-33VDC source can be isolated from the Negative Ground of the Battery
input to the inverter.
The inverter will switch oN when the external relay contact / switch is closed [External DC
voltage (10-33VDC) is fed to terminals 3 and 4 of the Terminal Block (10, fig 6.1a)]. The
inverter will switch off when the external relay contact / switch is opened [External DC volt-
age (10-33VDC) is removed from terminals 3 and 4 of the Terminal Block (10, fig 6.1a)].

1. Please ensure correct polarity of wiring connection. Positive (+) of the battery
voltage should be connected to Terminal 3. In case the polarity is reversed, the
oN/off control will NoT operate. The input to this terminal is protected against
reverse polarity
2. Use 1A fuse as shown as close to the battery input point as possible
The inverter will switch oN when the external relay contact / switch is closed [Voltage from
the 12V / 24V battery supplying the inverter is fed to terminal 3 of the Terminal Block (10,
fig 6.1a)]. The inverter will switch off when the external relay contact / switch is opened
[Voltage from the 12V / 24V battery supplying the inverter DC voltage is removed from
terminal 3 of Terminal Block (10, fig 6.1a)]. in a vehicle / RV, the control voltage may be fed
directly from the ignition Switch. this will switch on the inverter when the ignition is on
and switch oFF the inverter when the ignition is switched oFF.
