Overview of Installation Steps
Connect the power electronics supply voltage
Connect the heating circuits
Connect the temperature sensors (PT100)
Connect the optical fibers
Connect the control electronics supply voltage via the mains socket
Short-circuit caused by frayed ends
Provide all stranded individual wires with suitable connector sleeves before their con-
nection to the respective terminal / terminal block.

Connecting the Power Electronics Supply Voltage
Destruction of electrical components by overvoltage!
Connect only a Y-connected supply line (3 P + N + PE).
The supply voltage may be 230 V, 50
–
60 Hz maximum.
1.
Unscrew two screws from the case cover.
2.
Remove the case cover and pull off the ground conductor.
3.
Select the wire cross-sections according to the current load and the circuit fuse.
4.
Carefully connect the wires of the supply line to the terminals L1, L2, L3, N and PE of
the plug-type terminal strip X9. Firmly tighten the clamping screws.
