1.INTRODUCTION

This document defines the installation and wiring for the 092-100 Parallel To Series Changeover Switch. The parallel to series changeover switch provides a momentary 24V power source from two batteries that are normally connected in Parallel. When the rocker switch on the front of the device is put in the ‘I’ position, the batteries are switched into a series configuration. The 12V power supply is disconnected and the unit supplies 24V.

2.SYSTEM SPECIFICATION

Max Current Rating: 30A Continuous

3.INSTALLATION To install the unit, complete the following steps:

1. Mount the unit in a suitable position using the four screw holes provided inside the case. 2. Connect the wire labelled “BAT1-“ to the negative terminal of the first battery. DO NOT

CONNECT THE NEGATIVE TERMINAL OF THIS BATTERY TO COMMON GROUND. 3. Connect the wire labelled “BAT1+” to the positive terminal of the first battery. 4. Connect the wire labelled “BAT2- + E” to the negative terminal of the second battery, and also

connect this wire to the common ground. This can be the chassis or the ground wires of all electrical equipment.

5. Connect the wire labelled “BAT2+” to the positive terminal of the second battery. 6. With the rocker switch in the ‘0’ position, and no charging source connected, a voltage of

approximately 12V should be present at the wire labelled “12V from vehicle”. A voltage of 0V should be present on the wire labelled “24V out”.

7. Switch the rocker switch to the ‘I’ position. The relays in the device should operate. With the switch still pressed, check that the wire labelled “12V from vehicle” has a voltage of 0V and the wire labelled “24V out” has a voltage of approximately 24V.

8. Connect the wire labelled “12V from vehicle” to the 12V charging source. This can be either a 12V battery charger or the trailer connector.

Connect the wire labelled “24V out” to the 24V equipment that is to be powered by this unit.

4.OPERATION

When a 12V charging source is connected both batteries will be charged in parallel. Upon switching the rocker switch to the ‘I’ position, the battery charger will be disconnected and the 24V equipment will operate.

5.NOTES

Do not connect anything to the batteries other than this device. All 12V equipment should be connected to the wire labelled “12V from vehicle”. All 24V equipment should be connected to the wire labelled “24V out”. Failure to do this will result in improper operation of the unit.
