Sure Power 71030i Installation Instructions Manual

71030i DC-DC CONVERTER

1. It is recommended that the batteries be disconnected prior to installation.
Reconnect the batteries after the installation is complete

2. Mount converter in a convenient, well ventilated area. Use 16AWG wire
with a voltage rating of at least 150V to connect to power source. Use
14AWG for the ground and 12V outputs.

3. Terminal #4, #5, and #6 (“GND 12V”): Make ground connections first.
Using 14AWG all three pins must be used for ground connection.

4. Terminal #7 and #8 (“SW 12V”): Using 16AWG connect both pins to 12V
loads. These pins are switched On/Off with activation of Ignition, Terminal
#3.

5. Terminal # 3 (“IGN”): Using 16AWG connect to a switched 12V source. For
always ‘ON’ operation this pin can be connected directly to 12V source.

6. Terminal #9 and #10 (“UNSW 12V”): Using 14AWG connect both pins to
12V loads. These terminals supply continuous 12V power.

NOTE: THE SUM OF TWO OUTPUT LOADS (12V SWITCHED AND
12V UNSWITCHED) CANNOT EXCEED 30 AMPS.

7. Terminal #12 (“72Vin, 80Vin, 96Vin”): Using 16AWG with a minimum
rating of 150V, connect to positive terminal of power source.

8. Terminal #1 (“GND POWER SOURCE”): Using 16AWG with a minimum
rating of 150V, connect to negative terminal of power source.
