ELECTRIC WIRING

INSTRUCTIONS - DIN Electrical Connector

Wiring the electrical connector:

1. Remove the connector screw first, and then use a flat screwdriver to pry apart the two

connector halves. Note that the screw placed in the connector locks the two halves

together.

2. The center terminal is an optional ground that is normally used with AC current, and not

normally used with DC current.

3. When used with a solenoid valve, the polarity for the power con-nections is not

important. The two power wires can each be con-nected to either of the side terminals.

With electric motor actua-tors, the polarity should be observed for both AC and DC

opera-tion.

4. Place the connector on the electric motor actuator or solenoid valve coil and hold in

place with the supplied screw.

5. There are two different types of connectors that you may be using, ½" NPT Conduit and

Lead Wire. If you are using the Lead Wire type, a jacketed multi-conductor wire is

recommended. A rubber grommet is compressed around the jacketed conductor to

make a seal. If a tight seal is not important, then any type of wiring can be used.
