Table 2.4 Terminal Description
2.4.5.3 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
frequency
converter
for
ease
of installation, as shown in
Illustration 2.20.
Illustration 2.20 Unplugging Control Terminals
1. Open the contact by inserting a small screwdriver
into the slot above
or below the contact, as
shown in Illustration 2.21.
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.
