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 frequency
converter will trip on warning / alarm 27, “Brake IGBT”. If the connection is closed between 104 and 105, the frequency converter will trip on warning / alarm 27,
“Brake IGBT”.
Normally closed: 104-106 (factory installed jumper)
Normally open: 104-105

Terminal No.

Function

106, 104, 105

Brake resistor temperature switch.

If the temperature of the brake resistor gets too high and
the thermal switch drops out, the frequency converter 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 in a proper way to ensure
optimum electrical immunity.

Field Installed Network Module options connection
Connections are made to the network options on the control card. For details
see the relevant network instructions. The cable must be placed to the left
inside the frequency converter and tied down together with other control
wires (see picture).
