MAINTENANCE INSTRUCTIONS
Periodic Maintenance Items. All other servicing must be performed by qualified service personnel!
• Verify P12 Battery Charger screen shows no fault condition and indicates normal operation
• Check fuses or circuit breakers to verify like new condition. Confirm no discoloration or corrosion exists and circuit breakers will manually
trip and reset.
• Check for proper ventilation and that no debris has collected on the fan shroud or items have been improperly stored around
the P12 Battery Charger.
• Check battery terminal connections (both at battery and at the P12 Battery Charger) for corrosion. Clean and reconnect immediately
upon signs of corrosion.
• Check batteries per manufacturer’s instructions and maintenance procedures.
• Check wire condition. Overheating due to excessively long or too small conductors will result in hardening of the insulation or burn
marks at connections. If any of these signs exist, immediately replace with proper sized conductors.
DC Output Fuse Replacement
• Replacement of DC output fuses.
a. CAUTION!! Before replacing output fuses disconnect all sources of AC and all DC batteries and loads from the charger.
If you are not comfortable working on electrical systems, do not proceed. Seek help from a qualified marine electrician.
b. Remove terminations cover from the charger.
c. The fuses are located on the lower right of the charger adjacent to the negative battery stud.
d. Carefully remove both fuses by pulling the fuse straight out from the socket.
e. Replacement fuses must be ATC
®
type fuses with ignition protected rating
(use of non-ignition protected rated fuses will render the entire
charger non-ignition protected, and therefore unsafe for use in an environment that requires an ignition protected rating)
.
Proper fuses are as follows: Model 7531, two 20A ATC
®
Fuses, Model 7532, two 25A ATC
®
Fuses.
