MCD3000 Series
MG.15.A4.22 - VLT is a registered Danfoss trademark 9
Installation
line contactor or shunt trip activated circuit breaker
must be used to totally isolate the motor in the event
of a fault condition.
When fitted with one of the kits from the following
table, MCD3000 units are inside delta capable. The
inside delta capability is additional to all normal
functionality and is totally automatic. No user
adjustment or settings are required.

Control wiring
The MCD3000 can be controlled using the local push
buttons, or via remote control inputs. Switch between
the local and remote modes using the
[LOCAL/REMOTE] push button.
The MCD3000 has four remote control inputs.
Contacts used for controlling these inputs should be
low voltage, low current rated (Gold flash or similar).
The Stop and Reset circuits must be closed for
the MCD3000 to run in remote control mode.
Push button control example:
Two wire control example:
ATTENTION
Simultaneously pressing the [STOP] and
[RESET] buttons causes the MCD3000 to
immediately remove voltage from the motor resulting in
a coast to stop. Any soft stop or D.C.Brake settings
are ignored.
Do not apply voltage to the control inputs.
The inputs are active 24 VDC and must
be controlled with potential free circuits.
The Par. Set input determines which of the two
MCD3000 motor parameter sets is operative. When a
start is initiated the MCD3000 checks the state of the
