DC Power Supply Connection – Terminal Block Connector

Note: Ignore this supplement if the unit is AC-powered.

DC-powered units are equipped with a plastic 3-pin VDC-INpower input connector, located on the unit rear panel. Supplied with such a unit, is 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.

Caution: Prepare the connections to the TB plug before inserting it into the VDC-INconnector.

Preparing and Connecting the TB Plug

Refer to Figure 1 for assistance.

1.Strip the insulation of your power supply cable wires according to the dimensions shown.

2.Place each wire lead into the appropriate TB plug terminal according to the voltage polarity mapping shown in Figure 2.

(If the terminal is not already open, loosen its terminal screw.)

3.Tighten the three terminal screws.

4.Pull a nylon cable tie (supplied) around the power supply cable to secure it firmly to the TB plug grip (pass the tie through the holes on the grip).

leads using a plastic sleeve or insulating tape, to prevent the possibility of short-circuit.

6.Connect the assembled power supply cable to the unit by inserting the TB plug into the unit’s VDC-INconnector, until it snaps into place.

DC Power Supply Wire Voltage Polarity

Refer to Figure 2 for proper mapping of the power supply wire leads to the TB plug’s three terminals.

Warning:

Reversing the wire voltage polarity can cause serious damage to the unit!
