Electrical Installation of Control
The main’s supply must be 115/230 VAC, 50/60 Hz, 2/1 A. The 115/230 power requirement is field-switchable.
The power module accepts a standard IEC line cord (supplied).
To connect the line cord, follow these steps:
1. Attach the line cord clamp to the bottom surface of the VC3700, using the two screws on either side of the power
module.
2. Insert the line cord into the power module
3. Tighten the line cord clamp to prevent inadvertent loss of power.
Note! The line cord supplied can either be directly wired to a branch circuit or (with the proper plug type)
plugged into a 115 or 230 VAC outlet socket. The wire colors of the supplied line cord are as follows:
Mains Voltage and Fuse Selection
The fuse holder on the bottom panel of the power module contains the fuse drawer, which allows for either 115VAC
or 230VAC operation (Figure 7).
To replace or check mains fuses, follow these steps:
1. Remove all electric power from the unit.
2. Remove the line cord.
3. Use a small screwdriver to open the hinged door of
the fuse holder.
4. Remove the fuse drawer (ensure that the fuses in
the holder remain in place).
5. The drawer is labeled “230V” and “115V.” Rotate the
drawer to the appropriate voltage.
6. For line-to-neutral operation, use the shorting clip
(jumper) and one fuse. Shorting clip must be on left
side (when rotated to read the correct voltage). For
line-to-line operation, use two fuses.
7. Replace the drawer in the fuse holder and close the
door of the fuse holder.
8. The operating voltage shows through the window in
the fuse holder door. Ensure that voltage is correct.
9. Replace the line cord.
