WARNING: Correct DC Wiring is Required
The DC wiring used must be of appropriate size. An individual over-current protection device usually
within 20cm of each battery bank is required. A DC disconnect switch is also recommended. Both
devices must be rated for DC voltage and current and be rated to withstand the short circuit current
available from the connected battery bank. Both devices must match with the size of the DC wiring.
The unit is grounded through the ground stud located near the DC Output terminals, refer Section 3 on
Page 10 and 11.
For caravan, RV and other mobile applications the unit should be grounded with a minimum 4mm2
conductor.
For marine applications the unit shall be grounded to the main DC negative bus with a separate
conductor the same capacity (size) as the DC positive conductor.
