Installing the VTC-1D
The VTC-1D must be installed by a qualified electrician.
Before installing or servicing the VTC-1D, switch OFF the power supply at the
source.
Install the VTC-1D and all equipment connected to it according to local electrical
codes.
Mount the unit on a sheltered, vertical surface, with the electrical knockouts facing
down.
Use a screwdriver to tighten the screws in the enclosure. Do not use a drill or over
tighten the screws; this can crack the enclosure and ruin the watertight seal.
Use the electrical knockouts for bringing wires or cables into or out of the
enclosure. Use watertight strain reliefs or conduit connectors at all cable-entry
points.
Before removing electrical knockouts, remove the cover to prevent damaging the
control. Do not make additional holes in the enclosure; this can damage the
watertight seal or components and void the warranty.
Only permanent split capacitor motors appropriate for variable speed control, or
shaded pole motors, can be used on the variable stages.
Fill out the information below to help configure your control and verify that you do not exceed the electrical
ratings of the VTC-1D.
