Supplies Needed - Blue Sea Systems 7531 User Manual

Supplies Needed & Maintenance
1. AC Wire (see Table D page 5)
NOTE: Wire length must reach from the panel to the battery charger AC Connections with proper routing, support, drip loops, service loops, and termination.
2. DC Wire: Black or Yellow for negative and red for each positive. (see Table A page 5)
NOTE: Yellow is preferred for negative however diagrams are drawn in black for visibility.
3. Fuse holders for connection to each battery. (see Table B page 5)
4. Fuses for fuse holders. (see Table B page 5)
5. Screwdrivers
• Flat blade screwdriver to release cover latch
• Phillips #2 – for AC termination and cover screws, and strain relief wire clamps
• Phillips #3 – for mounting screws
6. Socket wrench
• 7/16" socket with extension and ratchet handle or nut driver – for DC wire terminations
• 10mm socket – for DC safety ground termination
7. Ring terminals
• #6 (M3) ring or snap spade terminals sized for AC/Supply wire gauge (quantity 3)
• ¼" or M6 ring terminals sized for DC wire sizes (quantity 4)
8. Crimping tool or obtain wires that are pre-terminated
9. Appropriate heat shrink if pre-terminated wires were not acquired
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.
• Per manufacturer's instructions, check batteries for 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
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

Installation & Operating Instructions
WARNING
Be sure the area around the charger and batteries is well ventilated while the batteries are being charged. This unit is must be located in a dry, well
ventilated area, free from unsecured hardware. Do not mount the unit directly above or below batteries to prevent corrosive electrolyte or gases from
damaging the unit.
EXTERNAL CONNECTIONS TO CHARGER SHALL COMPLY WITH THE UNITED STATES COAST GUARD ELECTRICAL
REGULATIONS ( 33CFR183 SUB PART I)
The P12 Battery Charger default startup mode is "User". The battery charger will maintain a voltage but will not
charge batteries in this mode. After proper installation see page 11 to set up your battery type.
Installation Steps
1. Before beginning electrical installation, disconnect all positive and negative AC and DC power sources.
DC AC
2. To reduce the risk of electrical shock, mount the battery charger vertically, in a dry and well ventilated location.
For drip proof installation, mount the battery charger in a vertical orientation.
NOTE: The charger should be located near the batteries to minimize wire length and its associated voltage drop to maximize charging efficiency.
If the batteries are not close together, place the charger near the largest bank of batteries.
3. The yellow latches are locked/released by turning them ¼ turn with a flat blade screwdriver.
4. Then remove the AC and DC wire termination strain relief clamps by unfastening the screws.
AC Connections Strain Relief
5. Route DC wires from each charger output to battery fuse holder, see Wiring Connections Diagram page 10.
NOTE: DC wiring should safely reach each battery positive and the battery negative common bus bar. Fuses should be installed at the battery positive
connections to prevent battery power from feeding back into a fault in the wiring, or in the battery charger. See Table A and B on page 5 for recommended values.
Best practices and ABYC standards recommend that every positive wire on the boat, outside the engine starting circuit, must have circuit protection.
Please reference ABYC E-11 electrical standard for the most up to date recommendations.
