3 Wiring Connections

Note:

Note that the connector block is unpluggable for convenience in making

wiring connections.

3.1 Power Connections

The Guard-It

autodialer requires 8 to 16 VDC power connected to the

connector block, in order to operate.

The power source should be capable of delivering a current of 500

milliamperes.

Power must be connected observing the correct polarity. Refer to the diagram.

3.2 Connecting To Electrical Ground

Your Guard-It

autodialer has several internal protective devices built in.

However, for them to work effectively it is important that the product be well

grounded. A grounding wire with a terminal lug is included on the product for

this purpose.

If the Product is mounted to a grounded metal back surface, then simply

connect the terminal end of the wire to the lower right hand mounting screw as

shown in the diagram.

If the product is not mounted to a grounded metal back surface, connect the end

of the wire to the nearest available electrical grounding point. If the installation

is within a grounded metal electrical panel or enclosure, connecting to the

metalwork will be sufficient. If you need to extend the ground wire, use 18

gauge wire or heavier, and keep the total length as short as possible.

This grounding wire will also ground the (-) side of the incoming 12 VDC

power. If you are using a pre-existing source of 12 VDC power, you will need

to verify that the grounding of the (-) side of this supply will not cause a

problem.
