ì=Voltage Selector Switch: Determines the voltage of the unit. By default, the unit is equipped for 115 VAC line voltage.
î Input Fuse: Make sure the fuse matches the input voltage (115 VAC or 230 VAC). Refer to Table B for a list of fuse values. If you use
230 VAC, you must replace the main fuse with a spare fuse that is supplied with your unit, and then change the voltage selector switch.
If 230 VAC is applied when the selector switch is set to 115 VAC, the fuse will blow.
ï Power: Attaches to the supplied power cord to provide power to the unit.
ñ Wiring Connectors for Individual Devices: A separate pin assignment is available for up to a maximum of 32 devices. Each connector
has a pin labeled + (Positive) and – (Neutral).
