Control Cable Routing - Danfoss VLT Automation Drive FC 300 Instruction Manual

3 How to Install
3.6.14 Brake Resistor Temperature Switch
Torque: 0.5-0.6 Nm (5 in-lbs)
Screw size: M3
This input can be used to monitor the temperature of an externally connected brake resistor. If the input between 104 and 106 is established, the
adjustable frequency drive will trip on warning / alarm 27, "Brake IGBT". If the connection is closed between 104 and 105, the adjustable frequency drive
will trip on warning/alarm 27, "Brake IGBT".

Normally closed: 104-106 (factory installed jumper)
Normally open: 104-105
Terminal No.
106, 104, 105
If the temperature of the brake resistor gets too high
and the thermal switch drops out, the adjustable fre-
quency drive will stop braking. The motor will start
coasting.
A KLIXON switch must be installed that is 'normally
closed'. If this function is not used, 106 and 104 must
be short-circuited together.

3.6.15 Control cable routing

Tie down all control wires to the designated control cable routing as
shown in the picture. Remember to connect the shields properly to ensure
optimum electrical immunity.
Serial communication bus connection
Connections are made to the relevant options on the control card. For
details, see the relevant serial communication bus instructions. The cable
must be placed to the left inside the adjustable frequency drive and tied
down together with other control wires (see picture).
