Locate power source as close to the unit as possible. Connect power with minimum of 18 AWG wires. Inputs TMP and FLT are used for monitoring cabinet tamper and power failure with normally closed contacts. These two inputs are for contact closure monitoring only, and do not use EOL resistor(s). If these inputs are not used, install a short piece of wire at the input to indicate safe condition.Observe POLARITY on VIN!Wiring for power, power fault, and cabinet tamperingVIN GND TMP GND FLT GND+ -12 to 24 VDC (wire pow stranded twisted pair, 1CABINET TAMPERPOWER FAULT33.3Memory Backup Battery
