1. Follow all Local, State, and National Electrical Codes when installing this equipment. The installation must be in
accordance with the Associated Location restrictions of the National Electric Code or Canadian Electrical Code as
applicable, including issues such as the routing, support and length of the involved cord of cable. All wiring shall be
enclosed and routed in accordance with Class 1, Division 2 wiring methods as specified in Article 501-4(B) in National
Electrical Code, NFPA 70. Overcurrent protection of the supply leads may be necessary. When determined necessary, use
a low .1A or .125A 600VAC fast acting fuse like KTK-1/10 or -1/8. Devices are intended to be panel or surface mounted.
The installation shall be used on a clean flat surface of a type 4X, 12, 13,or IP67 enclosure, or equivalent elevated ambient
rating.
2. The disconnecting means must first be suitably located and easily reached; and it must be marked as the disconnecting
device for the equipment. The Housing Front Display must be in visual proximity to the control panel ON/OFF disconnect.
Make sure to allow for enough wire length to properly route it back to the intended terminal locations with all necessary
bends. A minimum wire length of 6” must be maintained.
3. For 20mm KO mount, preassemble the small o-ring and channel ring (see PG. 4). For 3/4” KO mount, preassemble both
o-rings and threaded adapter (see PG. 5). For the best o-ring sealing performance, verify the external contact surface
around the panel knockout is clean, flat and free of debris. Feed wires through both KO hole and respective nut on the
inside. Tighten the nut before wiring (refer to Nut Torque PG. 8).
4. For Delta configured power, connect the 1 bar, 2 bar & 3 bar coded black wires (See PG. 9 Fig. 1 wire code) to L1, L2, & L3
respectively on the fused or disconnect side of the 3-Phase line voltage ( PG. 11). The Green/Yellow stripe (Grn/Yel) wire
MUST be connected to Earth Ground.
5. For Wye configured power with Neutral, use a 3-P WYE 5-WIRE device (see page 13 applications). The White wire
connects to neutral (N) and the GRN/YEL (GND) must connect directly to Earth Ground
(see PG. 9 Fig. 2 wire code).
