Battery Connection

WARNING: The installation of this unit may only be undertaken by qualified personnel with appropriate
training. High voltages in and around the battery and unit can cause serious injury or death. This unit must be
installed in accordance with rules and regulations at the site of installation.
WARNING: Choose a suitable battery fuse as outlined in the chapter "Important Safety Information" , section
"OVERCURRENT PROTECTION FOR BATTERY" .
WARNING: Ensure the battery cables are sized according to the table below. Inadequate battery cables can
cause excessive heat or fire during operation.
Recommended battery cable cross-section, battery size and fuse / DC circuit breaker rating:
Any-Grid model
Battery cable cross-section
Min. battery capacity (lead-based)
Battery current capability
Fuse / breaker rating
Steps to connect the battery:
1.
WARNING: Ensure the battery cables are not yet connected to the battery.
CAUTION: Ensure none of the cable insulation is jammed in the ring terminal before crimping.
Crimp one battery ring terminal (included) to each the positive and negative battery lead (unit side). If choosing
ring terminals other than the included ones, make sure they have an inside ring diameter of 6.4 mm, 0.25 in to fit
the M6 battery terminal bolts of the Any-Grid securely.
2. Remove the pre-installed nuts from the battery terminal bolts. Insert the ring terminal of the battery cables
through the casing holes and flat onto the corresponding battery terminal (Fig. 6). Screw down the previously
removed nuts with a torque of 2 ~ 3 Nm (1.5 ~ 2.2 lbf⋅ft). Ensure the ring terminals sit flush on the connectors.
CAUTION: Do not apply any anti-oxidant substances to the battery terminals of the unit before they are
adequately fastened.
CAUTION: Over-tightening the terminal nuts can cause damage to the terminal, under-tightening can
cause a loose connection and excessive heat during operation, make sure to use the prescribed torque.
3. Install the fuse holder or breaker in the positive battery cable (or negative, if the battery must be positive-
grounded).
WARNING: Ensure the fuse is not yet installed or make sure the circuit breaker is secured in the open
position for the rest of the installation procedure until instructed to do otherwise.
4. Connect the other end of the battery cables to the battery. Ensure the polarity of the battery terminals on the
Any-Grid match the battery polarity.
CAUTION: Reverse polarity connection to the battery may damage the unit.
