TYPICAL INSTALLATION WITH SWITCHED & UNSWITCHED LOADS
(Total load must be less than 30A)
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.

Summary

DC-DC Converter Installation Instructions

Battery Disconnection and Reconnection

Disconnect batteries before installation and reconnect only after completion.

Converter Mounting and Wire Gauge Requirements

Mount in a ventilated area. Use 16AWG for power, 14AWG for ground/12V outputs.

Ground Connections (Terminals #4, #5, #6)

Use 14AWG for all three pins for 12V ground connection.

Switched 12V Load Connections (Terminals #7, #8)

Connect to 12V loads, switched by Ignition (Terminal #3).

Ignition Input (Terminal #3)

Connect to a switched 12V source or directly for 'ON' operation.

Unswitched 12V Load Connections (Terminals #9, #10)

Connect to 12V loads for continuous power supply.

Total Output Load Limit

Sum of switched and unswitched 12V loads must not exceed 30 Amps.

High Voltage Input Connections (Terminals #12, #1)

Connect to positive (Terminal #12) and negative (Terminal #1) power source terminals.
