2.4.5.1. Power Connection
A permanently attached line cord supplies the AC power to the harsh enclosure version of the
IND570 terminal. The panel-mount enclosure is not supplied with a power cord –it is designed to
have AC or 24 VDC wiring brought directly to the rear of the chassis and connected to the incoming
power terminal strip.
2.4.5.1.1. AC Powered Models
When an IND570 is configured for AC power, the two AC power connections are marked "L" for line
(hot) and "N" for neutral as shown in Figure 2-28, Figure 2-29 and Figure 2-30. A loop terminal
and ground screw are provided for the ground connection on the panel mount. Harsh models have
the power ground installed with the region appropriate power cord.

NOTE: 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.
NOTE: The IND570 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.
ENSURE THAT THE POWER CONNECTION TO THE IND570 TERMINAL MATCHES THE SPECIFIED
OPERATING VOLTAGE OF THE TERMINAL. REFER TO THE DATA LABEL OF THE TERMINAL FOR THE
OPERATING VOLTAGE. CONNECTING THE INCORRECT POWER SOURCE TO THE TERMINAL COULD
RESULT IN DAMAGE TO OR DESTRUCTION OF THE EQUIPMENT AND/OR BODILY HARM.
