I) GENERAL INFORMATION

Your Phase Three™ Series Battery Charger represents a new phase
in charger design and performance, employing "smart" switching
circuitry which puts batteries through the optimum three-stage
charge process, adapts for gel-cell or lead-acid batteries, features
precise voltage compensation for varying battery temperature, is
rated for continuous duty and is housed in rugged stainless steel
cover coated with a durable white powder coat finish.
Following is a brief listing of some of the more important features/
options of your Phase Three Charger. Each is fully detailed later in
this manual:
•Three step "smart" charging: bulk, absorption, float
•Gel-cell/lead-acid switch selects optimum charge/float voltages
based on battery type
•Multiple output banks charge independently based on demand
•115/230 VAC, 50-60 Hz input – can be used anywhere in the
world
•Current limited – prevents damage in case of overloading
•Thermally controlled cooling fan allows continuous operation at
full-rated output
• High charge voltage time-out circuit prevents overcharging
during continuous high amperage demand
•Automatic high temperature power reduction – allows charger
output in over-temp conditions at reduced output current without
complete shutdown
•Optional temperature compensation sensor fine tunes output
voltage based on battery temperature
• Optional Remote Panel allows remote monitoring of charger
phase status and manual re-initialization of charge cycle
•Internal terminals allow installation of optional equalize timer
connection
•Use as a power supply without in-line battery; allows continued
use of DC powered electronics (when AC is available) in the event
that batteries must be taken off-line or removed
•Built to last - rugged stainless steel and aluminum case powder
coated case with marinized internal circuitry; optional-use
dripshield provided
•Ignition protected per USCG CFR 183.410
In addition, your Phase Three Charger carries a full two year
warranty against defects in materials or workmanship from the
date of purchase. Careful attention to these instructions should help
you enjoy years of trouble-free service.

II) Important Safety Instructions
1. SAVE THESE INSTRUCTIONS – This manual contains important
safety and operating instructions for the Phase Three Battery
Charger.
2. Before using this battery charger, read all instructions and
cautionary markings on (1) the battery charger, (2) the battery,
and (3) product powered by the battery.
3. CAUTION – To reduce the risk of injury, charge only 6 cell
(12 volt models) or 12 cell (24 volt models) gel-cell or lead-acid
rechargeable batteries. Other types of batteries may burst, causing
personal injury and damage.
4. Do not expose charger to rain or spray.
5. Use of an attachment not recommended or sold by NEWMAR
may result in a risk of fire, electric shock or injury to persons.
6. To reduce the risk of damage to the electric plug and cord (if
plugged into an AC outlet), pull by plug rather than cord when
disconnecting the charger.
7. Make sure the cord is located so that it will not be stepped on,
tripped over, or otherwise subjected to damage or stress.
8. An extension cord should not be used unless absolutely
necessary. Use of an improper cord could result in the risk of fire
and electric shock. If an extension cord must be used, make sure:
A) That pins on the plug of the extension cord are the same
number, size and shape as those on the plug of the charger.
B) That the extension cord is properly wired and in good electrical
condition.
C) That the wire size is large enough for the AC amperage rating of
the Phase Three Charger. Refer to the SPECIFICATIONS SECTION to
determine the full load input current of your Phase Three Charger,
and then use the chart below to determine the correct gauge wire
for any extension cord used.
