ELECTRICAL
The Rotational Control (BDCB
-
RC4HP) requires 24VAC 500Ma minimum input. The primary wiring must be in
accordance with Local Codes and that of the National Electric Code. Low voltage wiring must be isolated from primary
voltage lines and connections.
All units are provided with wiring diagrams and name plate data to provide information required for necessary field
wiring. Knockouts are provided on the cabinet for connection of power supply. Follow the color
-
coded schematic of low
voltage wiring that is located inside the BDCB
