Connecting the AC Line
The Si3540 is set for 110 VAC operation at the factory. If you use 110 VAC power,
all you need to do is install a power cord and plug it in. If you plan to use 220
VAC power, follow the instructions below.
Note: If you plan to hard wire the Si3540 to AC power, consult a qualified electri-
cian and observe all building and electrical codes. AC power can be dangerous.
220 VAC Instructions
In order to use 220 volts, you’ll need to change a fuse and a switch setting inside
the case.
• Remove all mating connectors from the drive.
• Set the drive on it’s widest side, so that you can read
Si3540 Programmable
Step Motor Driver properly.
• Remove the four (4) phillips head screws that mount the chassis sheet metal to
the chassis heat sink. See page 17 for a mechanical outline of the drive.
• The 110/220 switch is located near the position of the AC power connector, next
to the toroidal transformer (see sketch below).
• For 220 VAC operation slide the switch towards the bottom of the drive, or
towards the transformer end of the drive. The position of the switch is labeled on
the PC board also, “230” being for 200-240 VAC operation, and “115” for 100-120
VAC operation.
• Replace the fuse next to the switch with the 220 VAC fuse that came with the
drive. See technical specifications on page 18 to order more fuses.
• Replace the drive’s cover and assembly screws.

Installing an AC Line Cord
Remove about 5 mm (3/16 inces) of insulation from each of the three wires of your
line cord. (That’s right, three wires. For safety, always use a three wire power cord
on anything with a metal case). depending on where you got your power cord, it
may have black, white and green wires, or brown, white and green wires.
The AC power plug that was shipped with your Si3540 might be one of two types.
The “old style” is shown below, on the left. The “new style” , which comes with an
insulating rubber boot, is shown below, on the right.
Make sure you follow the proper sketch for your connector style.
Always unplug the line cord from the wall before attaching
it to the Si3540.
•Connect the black or brown wire to the Si3540 “L” terminal of the AC power
connector. That is the line, or “hot” connection.
•Connect the wite or blue wire to neutral, the “N” terminal.
•Finally, and most importantly, connect the green wire to the “GND” terminal. That
connects the Si3540 metal enclosure and DC power supply ground to earth ground.
