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 a permanent mounting points, by themselves.
Note: a.c. wiring for models PT-70CE and PT-24-35CE is through the bottom of the
unit. If the mounting location will make access difficult, proceed with a.c. wiring
installation before mounting the charger.
D) Drip Shield Installation: If the charger is vertically mounted in an area where
there is possibility that condensation or water leaks may occur overhead, installation
of the provided drip shield is strongly recommended. Use the four nylon stand-offs
and four nylon fasteners to install the drip shield as shown in FIGURE 1:
FIGURE 1: DRIP SHIELD INSTALLATION
Note: Diagram also depicts exploded view of fan and filter assembly (which have
been factory installed). These will be discussed later in this manual. The nylon
stand-offs and fasteners will snap into place though some force may be required if
they resist.
E) d.c. Output Wiring
NOTE: (For marine applications) THE INSTALLATION AND PROTECTION OF
VESSEL WIRING ASSOCIATED WITH BATTERY CHARGERS SHALL COMPLY
WITH ABYC STANDARDS E-8) AC ELECTRICAL SYSTEMS ON BOATS, E-9)
DC ELECTRICAL SYSTEMS ON BOATS, AND A-20) BATTERY CHARGING
DEVICES.
Note: Only qualified service personnel should access the output terminals of the
charger.
Pull off the black plastic terminal cover at the bottom of the front panel to expose the
d.c. output terminals and attach d.c. wiring with ring lug connectors only.
Ring lug connectors have been provided to suit most common installations. If the
wiring for your installation is not properly matched for the provided lugs, appropriate
lugs must be obtained prior to installation.

The d.c. wire size table on this page may be used to determine the correct gauge
wire, based on the model you have and the distance from the charger to the batteries.
Wire size depends on the amount of current the charger is designed to deliver, and
is unrelated to input/output voltage.

Two typical d.c. wiring configurations are illustrated in FIGURES 2 and 3. Note: If
you are only charging one or two battery banks you may simply ignore the remaining
output terminal(s). The charger is able to deliver its full rated output through any
single bank, if necessary.

* Note: d.c. chassis grounding conductor
must not be more than one size under that
required for the d.c. charging conductors.
Note: This diagram does not illustrate a complete system. Refer to ABYC Standards
E-8) AC Electrical Systems on Boats, E-9) DC Electrical Systems on Boats, and A-20)
Battery Charging Devices.
IMPORTANT: Install fuses at batteries per ABYC recommendations.
