NOTE:
 When wiring bare wires, ensure that they are perfectly arranged to go through the wiring holes.
 If you install at Ta 45°C environment, use copper wires with voltage rating of 600V and temperature
resistance of 75°C or 90°C.
 If you install at Ta 45°C above environment, use copper wires with voltage rating of 600V and
temperature resistance of 90°C or above.
 To be UL installation compliant, you must use copper wires when installing. The wire gauge is
based on temperature resistance of 75°C, in accordance with UL requirements and
recommendations. Do not reduce the wire gauge when using high-temperature resistant wire.
 Use a flathead screwdriver to tighten the wires. The head width and thickness of the flathead
screwdriver are 5.5 mm and 1.0 mm.
