5.3 Terminal blocks
The location of the terminal blocks in the back of the controller
can be seen in the figure below.
If the SPC signal is connected from equipment which has a
different transformer, then the G0s from each transformer must be
connected to one another.
The rail with three screws in the middle of the back is insulated. It
can be used as measurement neutral. A connection must then be
made between the rail and measurement neutral (M) in the
terminal block.
The terminal for protective grounding only provides a connection
for a possible protective wire and has no connection in the device.
Clamp the cables together using straps or the like next to the
terminals in order to limit their mobility.
5.4 Cable lengths
The following applies when the TAC 24 V transformer is installed
in direct connection to TAC 2413:
• The cables to G, G0 and other terminal blocks on TAC
24 V actuators must not exceed 50 m in length, and shall have
a minimum cross-sectional area of 0,8 mm
2
. If the cables ex-
ceed 50 m in length, then the minimum cross-sectional area
should be 1,5 mm
2
.
• Cables connected to the terminal blocks KC1 and K1 to K6
must not exceed 100 m, and shall have a minimum cross-
sectional area of 1,5 mm
2
.
• Cables connected to terminal blocks types B, U, and X must
not exceed 200 m, with a minimum cross-sectional area of
0,5 mm
