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
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.
