located at the left hand side of the AC compartment is intended for use with AC Input ground
wire. The right hand side ground bus is intended for use with AC Output ground wire.
• Remove the left hand side AC knockout. Install the strain-relief clamp in the AC knockout.
• Run the AC input wire through the strain relief clamp.
• Connect AC Input wire Line 1 to L1, Neutral to N and Line 2 to L2 of the terminals and Ground
to ground bus.
• Secure the strain-relief clamp.
AC Output Wire Connection:
• Similar procedure as connecting the AC Input wire: remove the right hand side AC knockout.
Install the strain-relief clamp in the AC knockout.
•
Run the AC output wire through the strain relief clamp.
• For Line for Dual Output, connect AC output wire Line 1 to L1, Neutral 1 to N1 and Line 2 to L2,
Neutral 2 to N2 of the terminals and Ground to the ground bus.
•
Secure the strain relief clamp.
•
Place the AC compartment cover and secure with the four screws.
Unit Chassis Grounding Connection:
DANGER: The unit chassis has to be grounded properly. Never operate the Inverter-
Charger without proper grounding. Failure to do so may result in death or serious injury.
•
Connect the grounding cable’s ring terminal to the unit ground screw.
• Connect the other side of the cable to the common grounding point.
DC Input Connection:
CAUTION : Reversing the DC Input terminal will damage the unit and it cannot be
repaired. Damage caused by reverse polarity connection is not covered by the warranty.
•
Connect one end of the negative DC input cable to the Inverter-Charger DC negative terminal.
Connect the other end of the negative DC input cable to the battery negative terminal.
• Make sure the DC Disconnect Switch is in the OFF position.
• Connect one end of the positive DC input cable to the Inverter-Charger DC positive terminal.
Connect the other end of the positive DC input cable to one of the terminals of the DC
Disconnect Switch.
• Connect a DC input cable between the other terminal of the DC Disconnect Switch and one
side of the terminal of the fuse holder.
• Connect a DC input cable between the other terminal of the fuse holder and the battery
positive terminal.
• Install the selected fuse to the fuse holder.
• Turn DC Disconnect Switch to ON position.
Remote Display Connection:
• Install the RJ45 standard cable to your desired location. Please note polarity.
• Connect one end of the RJ45 cable to one of the two Remote 1or 2 port on the unit and the
other end of the cable to the Display Panel. Please note the polarity.
Optional Battery Temperature Sensor Connection:
• Insert the RJ45 plug from the battery temperature sensor to the Inverter-Charger’s Battery
Temperature Sensor port. Please note the polarity
• Select the battery for which you would like to monitor the temperature, connect the Battery
Temperature Sensor to the negative terminals of this battery.
Test the Installation:
•
Switch DC disconnect switch and all AC circuit breaker to ON to provide DC power to the unit.
• The status LED display will turn on. If AC input source is available, ‘Charging’ green LED turns
On. This indicates the unit is running in by-pass mode meaning AC output is running from the
AC input source.
•
Disconnecting the AC input source by turning OFF the 30A branch breaker. ‘Battery Power’
green LED will turns On. This indicates the unit is running in battery power mode.
• Plug in a small AC load like a 40W table lamp or small appliance to the AC socket to verify AC
is available.
