Note 1: The 12V/300W and 24V/300W solar panel sizes are for reference only and the related fuse size, length and wire
gauges vary with the solar panel size accordingly. Please consult the solar panel manufacturer for details.
Note 2: Fuse or Circuit Breaker installed should be no greater than 7
” from battery.
Note 3: Keep the connection between the House Battery bank and the charger as short as possible.
•
Detach the plastic cover of the DC wiring compartment by removing the two screws on its top.
•
Connect the
CH1 “+” terminal in series to one of the over-current protection device, the
disconnection device,
and finally to the “+” terminal of the House Battery bank
•
Connect the
CH1 “-” terminal to the negative terminal of the House Battery Bank.
•
Make all the “+” and “-“ wire connections on CH2 (Solar Array/Panel) and CH3
(Alternator/Start battery). See more details in
“DC Inputs and Output Wiring”.
•
Tighten all the bolts of the charger terminals to 4.0-5.0 N-m (35-45 lb-in) of torque. Do not
over tight as this may result in damage to the charger.
•
Replace the plastic cover to its original position, and secure the two screws on its top.
Note: All the charger
’s negative “-“ terminals are bonded together inside the unit with a thick bus bar, and isolated from the
chassis stud terminal ground.
Unit Wiring: Connecting the unit the right way
Note: This diagram is for a reference only. No cables, fuse/breakers, batteries or solar panels are supplied
with this unit. Local rules and regulations should be followed when installing this unit.
BTS Port Connection (optional Battery Temperature Sensor sold separately)
•
To install the Battery Temperature Sensor (BTS), simply connect the RJ12 plug from the
sensor to the
‘BTS’ port located next to the Remote Display Port on the unit.
•
Connect the other end the temperature sensor (ring terminals/lug) to the negative terminal of
the main house battery bank.
NOTE: For lithium and Program battery setting, the temperature sensor is not required and it would be ignored if
installed.
