Teledyne 460H instruction manual 2.3AC Power Connection

2.3AC Power Connection

Connect AC power to the instrument. A hole is provided on the bottom face of the enclosure for installing a ½” conduit fitting for routing the electrical wiring into the instrument. In order to maintain the IP (NEMA4X) rating of the enclosure, an appropriate sealed conduit connector should be used. Figure 2-3 below shows the location of the three terminal connector for the AC power. It is recommended that if multi-strand wires are used to make the AC connections, the wire ends should first be “tinned” with solder to ensure that the screw terminals can make a reliable connection to the wires.

CAUTION!

Disconnect power to the AC mains before making any electrical

connections to the Model 460H.

IMPORTANT!

A proper earth ground connection must be made to the receptacle labeled “Earth Ground” on the 3 pin AC connector. Failure to do so may result in a shock hazard and malfunction of the instrument.
