INSTALLATION
Disconnect and lock out all power sources before beginning the
installation.
1. Using the threaded nipple, connect the relay to the desired enclosure through a
knock out hole.
2. Secure with the conduit nut provided.
3. Connect coil:
• Choose the coil common lead (white with yellow stripe) and connect it to
the common (-) source termination point.
• Choose either the low voltage (24VAC/DC, white with blue stripe) or high
voltage (208-277VAC, white with brown stripe) lead, depending on the
application requirements, and connect it to the (+) source termination
point.*
NOTE: When connecting the control side of this device (#18 wires) to power
line circuits, provide current limiting at 7 amps max.
4. Connect relay contacts:
Output #1
• Choose the relay common lead (solid yellow) and connect it to the
switched load.
• Choose the relay N.O. (solid orange) and/or the N.C. (solid blue) lead and
connect it to the switched load.
Output #2
• Choose the relay common lead (solid violet) and connect it to the
switched load.
• Choose the relay N.O. (solid brown) and/or the N.C. (solid grey) lead and
connect it to the switched load.
5. Secure the enclosure and reconnect power.
