Teledyne 460H - Manual (Page 13)

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.
