Wiring
There are three 1/2 in. (trade-size) conduit knockouts on the NEMA 4X enclosure. To make wiring connections,
proceed as follows:
1. Loosen the four cover screws and remove the cover. Do not damage the O-ring seal.
2. Select the knockout to be removed. Place a screwdriver blade on the knockout near the edge. Apply a sharp
blow to the screwdriver handle to loosen the knockout.
3. For watertight connection to rigid conduit, connect an approved watertight conduit fitting to the conduit first, and
then connect the fitting to the A19QC control enclosure.
4. Insert wire through conduit opening.
5. Make wiring connections to the screw terminals. See Figure 2, Figure 3, and Figure 4.
6. Verify the O-ring seal is properly seated.
7. Replace the cover and tighten the screws.
!
WARNING: Risk of Electric Shock.
Disconnect the power supply before making electrical connections. Contact with components
carrying hazardous voltage can cause electric shock and may result in severe personal injury or
death.
AVERTISSEMENT : Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des
composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique
et de provoquer des blessures graves, voire mortelles.
IMPORTANT:
Use copper conductors only. Make all wiring connections in accordance with local, national, and
regional regulations. Do not exceed the A19QSC Control’s electrical ratings.
IMPORTANT:
Use the terminal screws supplied in the contact block. Using other terminal screws may cause
damage to the switch and will void the warranty.
