Wago Spring Terminals

A group of six Wago spring terminals are positioned to the left of the screw terminals.
These are used to connect the auxiliary supply and an external fan.The terminals
marked R' and S' are used to connect the single phase auxiliary supply to the Q-Drive.
This supply is required if the resolver position and encoder output signals are to be
maintained when the three phase supply is removed, i.e. during an emergency stop, it
does not supply power to the amplifier part of the drive. There are two terminals each
for R' and S'. It is vitally important to ensure that the same phase is connected to R and
R' and similarly that the phase connected to S is the same as that connected to S'. A
typical connection diagram is shown in Figure 10. on page 25 .
There are also a pair of terminals for the connection of an externally mounted fan, if one
is used. Fans can be fitted internally and if so then the internal power connector should
be used, leaving the external terminals free.
