Insert the removable terminal strips or connectors in the appropriate sockets on
•
either the main board or on the scale card.
• Ensure that the cable length from the terminal strip/connector to the terminal
housing is sufficient so that no strain is placed on the terminal strip or
connector assembly when the housing is in the fully open position.
After re-securing the back cover, tighten the cable grip sufficiently to provide a
•
water-tight seal around the cable. This procedure allows any internal cable
slack to be received through the cable grip.

Power Connection

A permanently attached line cord supplies the main power to the IND310drive
terminal. No voltage or frequency settings are required since the terminal includes
a universal power supply that operates from 87 to 264 VAC. The supply operates
with a line frequency of 49 to 61 Hz.
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 IND310drive 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.
