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 opti- mum 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
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 2. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and by the manufacturer of any equipment you intend to use in the vicinity of the battery. Review all cautionary markings on these products. PERSONAL PRECAUTIONS 1.

Page 5: Installation
4. Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge. 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) -
Page 6: C) Mounting
the charger should be relocated. For optimum performance and longer life the charger should not be located in an area of extreme high temperature. C) Mounting Important Pre-Installation Note: The wiring access port for a.c. input is located on the bottom of the charger. - Page 7 The fuse is not user replaceable. If this fuse blows the unit must be returned to NEWMAR or a qualified electronic technician for repair. Typical d.c. wiring configurations are illustrated in FIGURES 1 and 2.

Page 8: E) Multiple Unit Parallel Wiring
1) Use only another identical charger model (PT-70a or PT-24-40). 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 is required for either 115V a.c. or 230V a.c. applications. Caution (230V applications only): If a.c. input is derived from a source consisting of two HOT leads (phase-to-phase 230V a.c. input voltage) an external fuse or cicuit breaker must be used to protect the unfused (formerly NEU- TRAL, now HOT) lead.

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’ electrolyte (gel or liquid) which may be caused by sustained charg- ing at higher voltages. -
Page 11: B) Time-Out Circuit
FIGURE 4: Typical Charger Output Graph (into battery without load) * 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. When the charger switches to the float phase, it will remain in that phase regardless of current draw. -
Page 12: C) Gel-Cell/Lead-Acid Selector Switch
(Caution: Ensure a.c. input has been disconnected before proceeding) 1) Remove the five screws on the front panel and two screws on each side of the unit. 2) Remove the small cover plate on the lower end of the front panel. This will expose the fan assembly which is held in place by two guides attached to the main cover. -
Page 13: D) Remote Monitor Panel Option
PT-70a and PT-24-40. 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. In addition, the panel features a re-initialize button, which, when pressed, will cause the charger to restart the three phase cycle. - Page 14 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
FIGURE 6: Temperature Sensor and Remote Panel Installation 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 Without the temperature sensor installed the output of the charger will be at the nominal voltages specified in the chart below at 72°... - Page 16 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: (Caution: Ensure a.c.

Page 17: G) Cooling Fan
If the fan fails to operate when the charger is on and a load is applied, it may be in need of replacement. Replacement fans are available from NEWMAR. Specify part number 999- 1210-0, and refer to Replacement Fan with PCB connector. -

tion mode and remain there until current drops below 5-15 % of capacity or until the time-out circuit cycle is complete. B) Constant Versus Occasional Use In general, it is recommended that the charger be left connected continuously to the a.c. distribution system so that it will be in operation whenever a.c. -

Therefore it is able to power virtu- ally any d.c. powered device (within the unit's rating) without the battery attached in-line (if, for instance, the battery must be removed for any purpose and a.c. is still available).

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...
