2.1.2.3 Mounting the SK TI4-TU-BUS on the SK 200E
The screw fittings and seals required for installation are enclosed with the modules or are fitted to the intended
locations.
Mounting of the technology unit on the
SK 200E must be carried out as follows:
1. Switch off the mains.
2. Remove the two M25 caps on the required side
of the frequency inverter (right / left).
3. Remove the printed circuit board (with terminal
bar) from the BUS connection unit.
4. Install the SK TI4-TU-BUS with the enclosed
seal on the SK 200E using the 4 enclosed
bolts.
5. Screw in both of the enclosed M25 to M12
reductions from the inside of the connection
unit of the frequency inverter.
(Purpose: to avoid damage to the internal wiring in the area of the junction of the
SK TI4-TU-...(connector unit for optional external modules) to the SK TI4-… (frequency inverter connector unit))
6. Replace the printed circuit board (See point 3) and carry out the electrical connections.
7. Fit and screw on the SK TU4 module.
2.1.2.4 Wall-mounting the SK TI4-TU-BUS
The screw fittings (except for anchoring screws) and
seals required for installation are enclosed with the
modules or are fitted to the intended locations.
The connecting cable between the technology unit
and the SK 200E should not be longer than 30m.
1. Mount the SK TI4-TU-BUS connecting unit with
adhered seal on the wall-mounting kit. To do this:
Insert the 2 x cheese-head screws (enclosed with
wall-mounting kit) into the (countersunk) holes
from the outside and with the 2 x bolts (enclosed
with the wall-mounting kit) securely screw both
components together from the inside (BUS
connection unit).
2. Make a suitable cable connection between the technology unit and the frequency inverter. Take care that
there is appropriate screw fitting and sealing of the modules. The cable sets enclosed with the BUS
connection unit are not used.
3. Fit and screw on the SK TU4 module.
