IND310drive Installation Manual
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 2-3. Should the fuse blow, always replace the fuse with the same
voltage and amperage as specified.

Load Cell Configuration Options

The IND310drive supports both analog and digital (POWERCELL) load cells and
can be configured with a maximum of two scales. The following are the possible
configurations:
•
•
•
•
•
The location and wiring connections depend on the configuration of the terminal.
CMOS and MTX POWERCELL
There is a fixed amount of current for each POWERCELL cell channel. If the
IND310drive is configured for one scale (31L30x), then the limit is 800 mA, and if
configured for two scales (31L31x or 31L33x), then each POWERCELL channel
has only 500 mA available.
