Wr20D And Wr20D-2 - Intelligent LLEVO-W Manual

3.2.2 W20D and WR20D‐2

Mount remote mount relay in an easy to access location, typically at the power j unction box feeding the first
light fixture to be controlled, or directly into the fixture line voltage wiring compartment.

For best performance always mount the relay where its radio is not obstructed by metal enclosures or subject
to equipment with high EMF noise.

Verify that the relay is within 50 feet line of sight to the switch stations intended to control it and that radio
transmission is not obstructed by metal barriers.

Mount the relay to junction box or fixture using the 1/2" nipple and secure the relay using the 1/2" locknut
provided and mounting bracket.

Terminate the line voltage 120/277VAC power, neutral and fixture load output leads from the relay to the
load wires as required by NEC Code, cap off the unused leads.

If using the WR20D‐2 relay terminate the 2nd load control wires to the 2nd fixture or plug load as required by
NEC Code, cap off the unused leads.

Test 0‐10VDC wiring from the fixture for proper voltage and reverse wiring of the DC control leads before
connecting to the WR20D or WR20D‐2 relay.

Terminate the low voltage 0‐10VDC dimming control leads (Purple/Pink) using two 18AWG leads. Keep Class‐2
wiring separate from line voltage runs per NEC Code requirements.

Test relay for ON/OFF operation using the Test/Link button on the relay.

To link the relay to a LightSync G3 wireless switches refer to TB0401 and to link the relay to a LLEVO‐W
wireless controller refer to TB0402.
