(18 AWG) with applicable insulation colors for local code requirements.
Flexible wires must have a crimped ferrule or pin type terminal on the end.
• A power cable with a three-prong plug (with ground connection) that is applicable to the supply
connection
• Connected through a cable gland (strain relief) that holds the power cable securely and seals the
enclosure when tightened
• Does not have a locking type device on the plug

The manufacturer recommends the use of manufacturer-supplied electrical components, such as power cord,
connectors and strain relief fittings.
N O T I C E
Make sure that the cable sheath goes through the inner side of the enclosure to keep the environmental
rating of the enclosure.
The controller can be wired for line power by hard-wiring in conduit or wiring to a power cord.
Regardless of the wire used, the connections are made at the same terminals.
The power cable plug is used to connect and disconnect power to the controller. For installation in
conduit, the installed local disconnect is used to connect and disconnect power to the controller.
Refer to
Figure 9 and Table 2 or Table 3 to connect conduit or a power cord. Insert each wire into the
appropriate terminal until the insulation is seated against the connector with no bare wire exposed.
Tug gently after insertion to make sure that there is a secure connection. If necessary, remove the
connector from the PCBA for easier wiring of the terminals.
Note: Make sure that all of the cables stay below the cable limit line printed on the PCBA to prevent interferences
with the high-voltage barrier. Refer to
Figure 9 .
