68 DC1 variable frequency drive 12/13 MN04020003Z-EN www.eaton.com
3.5.2.3 Pre-wired control signal terminals
In the case of DC1 variable frequency drives with an IP66 degree of protec-
tion, the control signal terminals will be located under the terminal cover.
They can be plugged in in this configuration; the local controls will have
already been connected.
Figure 45: Wiring for local controls
The setpoint potentiometer will be connected to control signal terminals 5, 6,
and 7; the operating direction selector switch will be connected to
terminals 1, 2, and 3. These two controls will only be active if the control
level is assigned to the control signal terminals (P-12 = 0).
When the device is set to its default settings, the setpoint value can be set
using the potentiometer. Meanwhile, the REV – 0 – FWD selector switch can
be used to set the drive's operating direction (counterclockwise rotating field
mode – STOP – clockwise rotating field mode).
