D) D.c. Output Wiring - NewMar PT-24-45W Installation & Operation Manual

The charger may be mounted on either a metal or non-metal
surface*. You will require four screws (wood or machine screws,
depending on mounting surface) with washers, sized for 1/4"
holes, to mount the charger, plus two temporary holding screws.
Note that, in addition to the four permanent mounting holes in the
flanges, there is a hole in each mounting flange which is "keyhole"
shaped. This is provided to ease vertical installation.
*To comply with ABYC D.C. chassis grounding conductor (ABYC
A-20), connect a suitable sized wire to the ¼"-20 chassis grounding
stud near AC cable feed through.
Make a mark on the wall or bulkhead where each of the
keyhole slots will be located. Then drive a screw about halfway
in at each of these marks. Hang the charger onto the bulkhead
using the keyhole slots. Doing this will save you from having to
support the charger's weight while you are driving in the four
permanent mounting screws. Note: The keyhole slots may be
used for additional support screws but they are not to be used as
permanent mounting points, by themselves.
IMPORTANT: Although the charger is constructed of materials
and in a manner which makes it highly resistive to the corrosive
effects of moisture in the environment, the charger is not water-
resistant. Do not mount the charger where there is a possibility of
water entering the unit. Evidence of water entry into the charger
will void the warranty.

D) D.C. Output Wiring

Note: Only qualified service personnel should access the output
terminals of the charger.
Whether working with existing battery charger output wires or
installing new ones, make sure the battery(s) is disconnected
from these wires before connecting them to the charger's output
terminals.
For a secure installation D.C. output wires must be attached with
1/4" crimp ring lug terminals sized appropriately to fit wire gauges
as listed below.
The D.C. wire size table below may be used to determine the
correct gauge wire, based on the model you have and the length
of the wire run from the charger to the batteries. Once the output
wiring has been attached to the chargers output posts, install the
clear plastic terminal cover provided with the charger.
