•
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 factory-installed 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.
Before applying power, confirm that the power cord is wired properly for the AC
voltage where the terminal will be used (see Figure 2-4). The power cord connects to
the TB1 terminal strip on the controller PCB.

Power Requirements

The terminal requires 87 to 264 VAC with a line frequency of 47 to 61 Hz (20 watts
maximum) of power and is internally fused at 1.6 amp, 250 volts. The fuse is located
adjoining the main power connection on the power supply board as shown in
Figure 2-4. Should the fuse blow due to power line fluctuations or other reasons,
always replace the fuse with the same voltage and amperage as specified.
