3. Thread battery cables through left-side panel knockout; put the hole lug at one end of each battery cable to
DC input stud.
4. Secure the connection with two supplied M5x12 cross hex-
washer type nickel screws and washers as shown:
CAUTION
Reverse polarity connections would damage the unit and is not cover by the warranty. Ensure
correct polarity (positive to positive, negative to negative) before completing connections
between battery and INEX inverter unit.
5. Install the other end of battery cables to battery or 48Vdc source.
WARNING
DC source voltage should be between 45V and 58V.
6. The three studs in the center of the backplane are AC output terminals. AC neutral, ground and line are
marked as UC3, UC4 and UC5, respectively. Check the AC output voltage. Using Table A, as well as local
wiring rules, choose appropriate gauge wire.
7. Thread AC neutral and line wires through left-side panel knock-out, put the hole lug at one end of each wire to
AC neutral and AC line studs.
8. Secure the connection with two supplied M5x12 cross hex-washer type nickel screws and washers as shown.
9. Install the other end of wires to the AC distribution or load.
10. AC Ground stud (UC4) is mainly for inter-connection with extra
shelves. To do system grounding, cover up the backplane with
the rear cover first, and screw the ground wire on the rear cover
with the supplied cross hex-washer type nickel screw as shown:
DANGER
To meet CEC/NEC requirements – to prevent fire, electric shock, improper operation of circuit
protection devices, as well as improper operation of the equipment – an electrical bond between
neutral and ground is required at the AC source or distribution point of an inverter system.
Ensure that the installation complies with the specific wiring rules applicable to your country or
area of jurisdiction.
