Good Installation Practice
Flexible installation options
A major benefit of Danfoss' decentralized concept
is saving installation cost partly due to the clever
two-part design of the DMS 300/FCD 300
All electrical installation is done inside the installation
box prior to mounting the electronic part. Subsequently
the electronic part is plugged into the installation box,
fixed, and the drive is ready for operation.
Power line looping
The FCD 300 and DMS 300 series facilitates internal
power line looping. Terminals for 0.08 in (4 mm)
cables inside the enclosure allows connection of up
to 10+ units. FCD 300 and DMS 300 can be mixed
along the line. Average load must not exceed 25 A.
24 V control back up
External 24 V (20-30 V) DC can be connected
in the EX and EB versions for back-up of control
circuits. This way communication and programming
possibility are maintained even during power down.
The terminals are dimensioned for up to 0.1 in (2.5
2
mm)
and are doubled for looping.
The T63 and T73 installation boxes have additional
looping terminals for 2 X 24 V with 0.15 in (4 mm)
Connected sensors can be supplied separately
from the control back up supply.
