Customer-supplied 230 V supply is required for mains contactors.

5.4.4 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 trips
on warning/alarm 27, Brake IGBT. If the connection is
closed between 104 and 105, the frequency converter trips
on warning/alarm 27, Brake IGBT.
Install a Klixon switch that is normally closed. If this
function is not used, short circuit 106 and 104 together.
Normally closed: 104–106 (factory installed jumper)
Normally open: 104–105
Terminal No. Function
106, 104, 105 Brake resistor temperature switch.
Table 5.23 Terminals for Brake Resister Temperature Switch
NOTICE
If the temperature of the brake resistor gets too high
and the thermal switch drops out, the frequency
converter stops braking. The motor starts coasting.

5.4.5 External Fan Supply

If the frequency converter is supplied by DC, or if the fan
must run independently of the power supply, apply an
external power supply. The connection is made on the
power card.
Terminal No. Function
100, 101 Auxiliary supply S, T
102, 103 Internal supply S, T
Table 5.24 External Fan Supply Terminals
The connector on the power card provides the connection
of mains voltage for the cooling fans. The fans are
connected from factory to be supplied from a common AC
line (jumpers between 100–102 and 101–103). If external
supply is needed, the jumpers are removed and the supply
is connected to terminals 100 and 101. Use a 5 A fuse for
protection. In UL applications, use a Littelfuse KLK-5 or
equivalent.

5.4.6 Relay Output D Frame

Relay 1
•
Terminal 01: common
•
Terminal 02: normally open 400 V AC
•
Terminal 03: normally closed 240 V AC
Relay 2
•
Terminal 04: common
•
Terminal 05: normally open 400 V AC
•
Terminal 06: normally closed 240 V AC
Relay 1 and relay 2 are programmed in 5-40 Function Relay,
5-41 On Delay, Relay, and 5-42 Off Delay, Relay.
Use option module MCB 105 for additional relay outputs.
