DC Power Supply Connection – Terminal Block Connector
Note: Ignore this supplement if the unit is
AC-powered.
Certain DC-powered units are equipped with a plastic 3-pin
VDC-IN power input connector, located on the unit rear panel.
Different variations of the connector are shown in Figure 1. All
are functionally identical.
Supplied with such units is a kit including a mating Terminal
Block (TB) type connector plug for attaching to your power
supply cable.
Connect the wires of your power supply cable to the TB plug,
according to the voltage polarity and assembly instructions
provided below.
