Connecting the Heating Circuits
Destruction of electrical conductors by overheating!
Observe voltage drop for large conductor lengths.
3.3.1
Connecting Single-Phase Heating Circuits
Connect the heating circuits via the 3-pole terminal blocks to plug-type terminal strips X1
(channel 1) to X8 (channel 8):
1.
Connect wires 1, 2 and PE of the respective actuator to the 3-pole terminal block.
2.
Insert the terminal block into the respective plug-type terminal and check firm seating.

Connecting Two-Phase Heating Circuits
Connect the two-phase heating circuit to two adjacent terminal blocks, e.g. X1 (channel 1)
and X2 (channel 2):
1.
Connect wires according to Table 3-3.
2.
Insert terminal blocks into the respective plug-type terminal strip and check firm seating.
Note
3.
In this example, connect the temperature sensor (PT100) to plug-type terminal strip
X10, terminals No. 1/2. Controlling channel = channel 1.
