Power Connection

A permanently attached line cord supplies the AC power to the harsh enclosure
version of the IND560 PDX terminal. The panel-mount enclosure does not provide
an AC power cord—it is designed to have AC wiring brought directly to the rear of
the chassis and connected to the AC power terminal strip. Note that the two AC
power connections are marked "L" for line (hot) and "N" for neutral. A loop
terminal and ground screw are provided for the ground connection.
No voltage or frequency settings are required since the terminal includes a
universal power supply that operates from 85 to 264 VAC.
The integrity of the power ground for equipment is important for both safety
and dependable operation of the terminal and its associated scale base. A
poor ground can result in an unsafe condition should an electrical short
develop in the equipment. A good ground connection minimizes extraneous
electrical noise pulses. The IND560 PDX should not share power lines with
noise-generating equipment. To confirm ground integrity, use a commercial
branch circuit analyzer. If adverse power conditions exist, a dedicated power
circuit or power line conditioner might be required.
FOR CONTINUED PROTECTION AGAINST SHOCK HAZARD CONNECT TO
PROPERLY GROUNDED OUTLET ONLY. DO NOT REMOVE THE GROUND PRONG.
