There are different wiring options for the IP710 and DS710 dimmers based on your application:
1) Dimmer directly to the fixture for dimming and switching
2) Dimmer to the fixture for dimming ONLY (part of larger lighting system)
3) Dimmer to the fixture through a power pack (may be part of a larger lighting system)
When the IP710 is used with the OPP20, there may be an incorporation into a larger lighting controls system. Please refer to the OPP20 “application cookbook” for more details on using multiple 0-10V sensors in conjunction with the IP710. Additionally, these dimmers can be wired in single pole or 3-way applications with a standard 3-way switch. See the instruction sheet for 3-way wiring diagrams.
