1.
Open the contact by inserting a small screwdriver
into the slot above or below the contact, as
shown in Illustration 2.17.
2.
Insert the bared control wire into the contact.
3.
Remove the screwdriver to fasten the control wire
into the contact.
4.
Ensure the contact is firmly established and not
loose. Loose control wiring can be the source of
equipment faults or less than optimal operation.
See 10.1 Power-dependent Specifications for control terminal
wiring sizes.
See 6 Application Set-Up Examples for typical control wiring
connections.
