Before proceeding, consult the product nameplate and determine the operating temperature of the beacon. 277 Vac NOTE: To comply with NEC Section 300-14, which requires a minimum of 6 inches (15.25 cm) of free conductor at a junction, when mounting the Model 191XL, the mounting pipe used to join the unit to a splice box should be no longer than 10 inches (25.4 cm). The Model 191XL has provisions for mounting a 3/4" pipe and can be mounted in any position. 1. Before mounting the beacon, ensure that the mating threads are clean. 2. To prevent the ingress of water and dust, apply conductive sealant to the conduit threads prior to mounting. If nonconductive sealant is used, the enclosure must be earthed via the provided internal grounding wire/grounding screw to ensure proper grounding continuity.
Installation and Service Instructions 3. In high-humidity environments when units are mounted dome down, condensation may occur in the conduit system. Use properly rated conduit seals/drains to prevent moisture from entering the fixture. IMPORTANT: To prevent the connection from loosening, tighten the fixture to a MINIMUM torque of 5 ft-lb (6.8 N·m) after threading it onto the pipe. 4. Thread the fixture onto the 3/4" pipe and secure it with the set screw. 3/4" NPT PIPE Figure 1 Pipe-mounted beacon Model 191XL Series LED Beacon 191XL LIGHT ASSEMBLY 290A6881 9
