Gauge UL1015; Coil: 18AWG; Contacts: 12AWGInsulation Class 277VAC RMSAgency Approvals UL508 enclosed device listing, pollution degree 2V420V420DIMENSIONSNOTICE• This product is not intended for life or safety applications.• Do not install this product in hazardous or classified locations.• The installer is responsible for conformance to all applicable codes.• Mount this product inside a suitable fire and electrical enclosure.INSTALLATIONDisconnect 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.* Isolate or insulate all non-terminated wires according to local electrical code requirements, i.e. wire nut.2.0"(52 mm)2.5"(64 mm)3/4" NPT Nipple2.3"(59 mm)4.0"(103 mm)3.8"(97 mm)HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH• Follow safe electrical work practices.
