Page 2: I) General Information
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-step 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 a rugged stainless steel case. -
Page 3: Important Safety Information
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. - Page 4 PERSONAL PRECAUTIONS 1. Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery. 2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

Page 5: Installation
GROUNDING AND a.c. POWER CORD CONNECTION 1. The charger should be grounded to reduce the risk of electric shock. (For marine applications only) EXTERNAL CONNECTIONS TO THE CHARGER SHALL COMPLY WITH UL RECOMMENDATIONS AND/OR UNITED STATES COAST GUARD ELECTRICAL REGULATIONS (33CFR183, SUB-PART I) (For marine applications only) THE INSTALLATION AND PROTECTION OF VESSEL WIRING ASSOCIATED WITH BATTERY CHARGERS SHALL COMPLY WITH ABYC STANDARDS;... -
Page 6: C) Mounting
C) Mounting Important Pre-Installation Note: The wiring access port for a.c. input is located on the bottom of the charger. If the factory-installed a.c. cord must be changed for any reason, this should be done before mounting, as access will be difficult afterwards. The charger may be mounted on either a metal or non-metal surface*. - Page 7 ENSURE THAT LEADS ARE PROPERLY FUSED AT THE BATTERY. (REFER TO ABYC REC- OMMENDATIONS.) Typical d.c. wiring configurations are illustrated in FIGURES 1 and 2. FIGURE 1: Simple d.c. Wiring (Preferred Method) Note: These diagrams do not illustrate complete systems. Refer to ABYC Standards E-8) AC Electrical Systems on Boats, and E-9) DC Electrical Systems...

Page 8: E) Multiple Unit Parallel Wiring
Observe the following guidelines when wiring a parallel unit. 1) Use only another identical charger model. Do not use a different charger model, either from NEWMAR or from another manufacturer. 2) Wire length and gauge and wire lug size must be identical for each charger to ensure proper load sharing. - Page 9 a.c. input is "universal". Models PT-14 and PT-24-8 operate in a range of 85-264 VAC, 47- 63 Hz. No switch setting is required for either 115V a.c. or 230V a.c. applications. Models PT-25 and PT-24-13 operate in a range of 90-132 or 180-264V a.c., 47-63 Hz. Input volt- age selection for these models is made via a slide switch on the right hand side of the charger.

charger, it is highly unlikely that this fuse will blow unless there is some other malfunc- tion within the charger. This fuse is not user-replaceable. Replacement of the input fuse must be performed by a qualified service person. OPERATION A) Three Stage Charge Regimen The Phase Three Battery Charger utilizes the three stage charge regimen which is widely recommended by battery manufacturers for allowing the fastest possible recharge time without loss of batteries’... -
Page 11: B) Time-Out Circuit
A typical three stage charging cycle is illustrated in FIGURE 4. FIGURE 4: Typical Charger Output Graph (into battery without load) The bulk/absorption stages last approximately 10 hours maximum at factory setting. Note: If a load is applied during the absorption phase, the charger may revert to the bulk phase depending on the total current draw. -
Page 12: C) Gel-Cell/Lead-Acid Selector Switch
adjustment of the internally located time-out circuit adjustment pot may be recom- mended. The procedure is as follows: (Caution: Ensure a.c. input has been disconnected before proceeding) 1) Remove the two phillips head screws on the front panel (bottom right and just above the output terminals), as well as the two phillips head screws on each side of the unit. -
Page 13: D) Remote Monitor Panel Option
D) Remote Monitor Panel Option A Remote Monitor Panel is available from NEWMAR (model RP) which will enable you to monitor the charger’s status at-a-glance from a remote location. Red and green L.E.D.’s indicate whether the charger is in the bulk, absorption or float phase of the charge cycle. -
Page 14: E) Temperature Compensation Option
Either of these two conditions will shorten battery life. Therefore, the Phase Three charger is designed to utilize an optional remote sensor (available from NEWMAR; model TCS-12/24) which provides automatic temperature compensation. The remote sensor will signal the charger to fine tune its output voltage so that it is properly matched to the temperature of the battery/battery environment. -
Page 15: F) Equalize Timer Option
Installing the timer requires a mating connector with dual wires which are plugged into a jack on the internal charger function circuit board. The connector/wire assembly is available from NEWMAR. Request part number 873-3716-0, CFB Equalize 2 pin assembly. Proceed with the installation as follows: P.O. -
Page 16: Application Notes
(Caution: Ensure a.c. input has been disconnected before proceeding) 1) Remove the two phillips head screws on the front panel (bottom right and just above the output terminals), as well as the two phillips head screws on each side of the unit. 2) Carefully lift the main cover off of the charger base. -
Page 17: C) Proper Load Sizing
While the output regulation of the charger will minimize battery gassing and water loss, monthly checks of the electrolyte level (for wet lead acid batteries) are still strongly recommended. Some water loss is an inevitable aspect of the charging process, and maintaining the correct electrolyte level in your batteries is the most important thing you can do to assure their maximum performance and long life. -

Page 22: Battery Care Tips
Regular maintenance and proper care will assure you reliable service from the most depended upon and sometimes most neglected items, your batteries and battery charger. NEWMAR battery chargers are designed to keep your batteries fully charged but your batteries also need proper regular maintenance to provide a maximum life of service. - Page 23 which are not maintenance-free to require topping off about once a month. A battery’s state of charge may be monitored by checking the specific gravity or by open circuit voltage. You may use the following table to evaluate the condition of your batter- ies: Battery Condition Table Specific Gravity...
