2.4.3.1. AC Power Connection
A permanently attached line cord supplies the AC power to the AC version of the IND246 terminal.
Note that the two AC power connections are marked "L" for line (hot) and "N" for neutral as shown
in Figure 2-6. A loop terminal is provided on the ground wire 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 IND246 should not share power lines with
noise-generating equipment. To confirm ground integrity, use a commercial branch circuit
