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. 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. 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 the best O-ring sealing performance, verify the inside contact surface around the panel knockout is clean, flat
and free of debris.
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).
6. For DC configured power see "DC Applications" on pages 12 & 14.
