2.4.1 Input Voltage Selection

As shipped from the factory, the 230/460 V model is set for 460 volts input and the 400/440 V model is set for 440 volts input.
If you will be operating the machine from a 230 V or 440 V source, open the switch access panel on the rear panel of the
machine and flip the Voltage Selector Switch to the 230 V or 440 V position. See Figures 2-3a or 2-3b.

Line Voltage Fluctuations
The MTS 3500i is designed to compensate for line voltage variations of plus or minus 10 percent from the rated level while
maintaining rated output, without damage to internal components. If line voltage fluctuations exceed this range, serious
damage could occur. Therefore, prior to installation, it is recommended that the line voltage of the supply circuit be mea-
sured at several times during the day. If fluctuations beyond the +/-10% level are detected, another supply circuit should
be selected, or the local power company should be asked to adjust the supply. In addition, certain types of factory equip-
ment can cause rapid voltage swings (transients) which can cause the MTS 3500i safety circuits to "trip". Examples of such
equipment are resistance welders, punch presses, and starting of large electric motors.

2.4.2 Fuse Replacement

The 230/460 V model requires a 4 Amp, 500 V Slo-Blo fuse. The 575 V and 400/440 V models require a 2 Amp, 600 V Slo-Blo
fuse. Replace fuse with the same type and rating only.
