Installation Instructions; Initial Charger Setup - Blue Sea Systems 7531 User Manual

Installation Instructions

(continued)
6. Route the AC wires from the charger to the AC panel and terminate wires at the charger.
7. Make the AC source connections to the appropriate panel circuit breaker and leave in the "off" position. (see Table D page 5).
The connection to the supply mains is to be in accordance with the national wiring.
NOTE: Connect AC wiring, but do not energize the circuit until AC insulating cover is installed, DC is connected, and DC fuses are installed.
8. Recommended Connection: Attach the battery temperature sensor wire to the largest battery bank. If all battery banks are the same size attach to bank with the most loads.
Blue Sea Systems recommends using a high quality dielectric grease for remote control and temperature sensor connections.
a. Attach the sensor in the center of the long side of the battery.
b. If multiple batteries are in a battery bank attach sensor
in the center between multiple batteries.
c. When external circumstances could create a significant
difference in temperature on one side of a battery versus
another, always attach temperature sensor on warmest side.
9. Install appropriate DC Fuses. (see Table B page 5)
10. Confirm all connections are accurately installed per
Wiring Connections Diagram.
11. Secure AC and DC strain relief covers and fasten down.
12. Secure the termination cover back over the connected wires
and latch the yellow tabs.
13. Restore AC power and turn on the AC supply circuit
breaker to the battery charger.
14. Perform the chargers setup procedure as outlined in
Initial Charger Setup page 11.
Wiring Connections
NOTE: The external
shutdown input is a ¼"
male quick connect.
Applying a voltage
between +5 and +32
volts DC (referenced to
the battery negative)
will place the charger
into standby mode.
When the voltage is
removed, the charger
will resume charging.
If the installation does
not require use of this
terminal, it may be
Neutral
left unconnected.

WARNING
If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
All-pole disconnection from the supply mains incorporated in the fixed wiring shall be provided in accordance with AS/NZS 3000.
Optional Installations see pages 22–23
1. Attach the battery charger remote connection to the back of the P12 Battery Charger Remote using dielectric grease. Connect to the Remote Display/Com
port of the charger.
2. Connect the Automatic Charging Relay(s) (ACR) wire to the ACR Connection port(s)
NOTE: If you have a Blue Sea Systems ACR with Start Isolation it is possible to take advantage of the P12 Battery Charger's ability to integrate with it. The
P12 is designed to charge three electrically independent batteries or battery banks. The P12 has the unique capability to individually move each battery out of
Absorption charging stage. This ensures batteries near their full charge do not continue to receive high constant voltages necessary in the Absorption stage. This
is optimal treatment for long battery life. Charge Coordination integrates with the Blue Sea Systems family of Automatic Charging Relays (ACR) to force separation
of the battery bank while the P12 is operational, to allow the batteries to individually exit the absorption stage. (see pages 22–23)
