Chassis Grounding Connection
DANGER
THIS CHARGER REQUIRES CORRECT GROUNDING.
The unit chassis has to be grounded properly. Never operate the Charger
without proper grounding. Failure to do so may result in poor charger
performance, serious injury or possible death.
Connect the unit’s chassis ground to the common ground point through
the ground stud located near one of the unit mounting slots. See image in
Section 3, page 10.
DC Output Wiring
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.
