DC Disconnect and Over-Current Protection
For safety and to comply with regulations, battery over-current protection and disconnect devices are
required. Fuses and disconnects must be sized to protect the DC cable size used, and must be rated for DC
operation. Do not use devices rated only for AC service – they will not function properly.
Note that some installation requirements may not require a disconnect device, although over-current
protection is still required.
Battery Cable Connection
Observe Battery Polarity! Place the ring terminal of the DC cable over the bolt and directly against the
inverter/charger’s battery terminal. Tighten the M8 screw to 5-8 Nm. Do not place anything between
the flat part of the Backup terminal and the battery cable ring terminal or overheating may occur.
DO NOT APPLY ANY TYPE OF ANTI-OXIDANT PASTE TO TERMINALS UNTIL AFTER
THE BATTERY CABLE WIRING IS TORQUED!!
Figure 3 below illustrates the proper method to connect the battery cables to the inverter/charger
terminals.
WARNING: Shock Hazard. Installation must be performed with care for the high battery
voltage in series.
Caution!! Do NOT place anything between battery cable ring terminals and terminals on
the inverter. The terminal screw is not designed to carry current.
Apply Anti-oxidant paste AFTER terminals have been tightened.
Verify that the cable lugs are flush with the battery terminals.
Tighten battery cables to terminals (10~15 Nm).
