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. It is factory set for 115V. For 230V a.c. applications use a ball point pen or
similar tool to slide the switch into the 230V position.
a.c. input for the charger must be routed through fuse or circuit breaker on an a.c. distribution
panel with proper safety/earth chassis ground in accordance with all applicable local codes and
ordinances. Caution (230V applications only): If a.c. input is derived from a source consist-
ing 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 NEUTRAL, now HOT) lead.
Color coding of the installed a.c. cord is as follows:
Black.................................a.c. Hot (fused)
White.................................a.c. Neutral
Green................................a.c. Ground (safety, earth)
If the factory-installed cord must be replaced use a cord of equal or larger AWG rating
with stranded (not solid) conductors. Remove the a.c. input terminal cover by removing
the three phillips head screws securing it. Loosen the strain relief to slide the cover
assembly down the cord for terminal access. Note the configuration of terminal block
wiring as follows:

(In marine applications) All charger wiring should be installed in accordance with UL,
U.S. Coast Guard and/or A.B.Y.C. regulations and recommendations, as well as all
relevant local codes. See REFERENCE APPENDIX at the end of this manual for sources.
A note about the a.c. input fuse: The a.c. input of your charger is protected by an input fuse
which is located inside the unit. Due to the current limiting characteristic of the
