1. Strip the cable jacket for approximately 70 mm
(2.75") from the end of the cable, and thread the
wires through the gland
2. Connect the wires to the terminals as shown
above: the polarity is identified on the terminal
block.
3. Tighten the gland to form a good seal.
4. Close the cover and tighten screws: please do
not overtighten screws. Recommended torque is
1.1 to 1.7 N-m (10 to 15 in-lb).
