VC350A Flexoseal ® System
Valco Cincinnati 6-4
The main power supply must be either 120/240 VAC, 50/60 Hz or 100/200 VAC, 50/60 Hz. The 120/240VAC
power requirement is field-selectable. The
power-entry module accepts a standard IEC power cord, which is
supplied.
Connecting the Main Power Supply
To connect the main power supply to the control, follow these steps:
1. Select the voltage:
1a. Turn off the power switch on the power-entry module (Figure 6-4).
1b. If the power cord is attached to the power-entry module, remove the power cord.
1c. Using a small screwdriver, open the hinged door of the fuse holder.
Note! The fuse holder on the power-entry module contains the fuse drawer (Figure 6-5), which allows
for either 115 or 230 VAC operation.
1d. Remove the fuse drawer, ensuring that the fuse(s) in the holder remain in place.
1e. If the control will be connected to 115VAC , rotate the drawer so that 115V will show through the
door opening. If the control will be connected to 230VAC , rotate the drawer to the 230V position.
Electrical Installation of the Control
WARNING! Electrical installation should be accomplished only by experi-
enced service personnel! OTHERWISE, DEATH OR PERSONAL INJURY
COULD OCCUR.
WARNING! Ensure that the correct operation voltage is selected (see “Con-
necting the Main Power Supply” below) before turning the unit on. OTHER-
WISE, DEATH OR PERSONAL INJURY COULD OCCUR.
WARNING! Turn off the power and unplug the unit before switching the
power voltage or making any rear-panel connections. OTHERWISE, DEATH
OR PERSONAL INJURY COULD OCCUR.
1f. For line-to-neutral operation , use either the shorting clip and one fuse or or use two fuses. (The
shorting clip will be on the left side of the drawer when rotated to the correct voltage position as
shown in Figure 6-5.)
For line-to-line use , discard the shorting clip and use two fuses.
1g. Replace the drawer in the fuseholder in the correct voltage position and close the door of fuseholder.
1h. Ensure that the correct operating voltage shows through the window in the fuse drawer.
CAUTION! The control uses a 1A, 250V, SLO-BLO standard fuse for
115V operation and a 1A, 250V, SLO-BLO standard fuse for 230V
operation. No other type of fuse should be used. OTHERWISE, DAM-
AGE TO EQUIPMENT COULD OCCUR.
WARNING! The setup in step 1f may vary, depending on what coun-
try the system is being installed in. It is the purchaser’s responsibil-
ity to ensure that all local, county, state, and national codes, regula-
tions, rules, and laws relating to safety and safe operating conditions
are met and followed. OTHERWISE, DEATH, PERSONAL INJURY, OR
DAMAGE TO EQUIPMENT COULD OCCUR.
