Installation and startup may only be per-
formed by technically trained, skilled per-
sons who are familiar with the associated risks and
warranty provisions.
7.1
Installation steps
1. Please refer to the safety and warning notes
(
section 1 "Safety and warning notes" on page 3).
2. The information provided in the customized ROPEX
Application Report, which is prepared by ROPEX
specifically for each application, should be heeded
at all times.
3. All electrical components, such as the controller, the
impulse transformer and the line filter, should be
installed as close as possible to the UPT sealing
bar(s) in order to avoid long wires.
4. Connect the voltage measurement cable U
R
directly
to the UPT sealing bar and lay it twisted to the con-
troller (UML-1 voltage measurement cable
section 4 "Accessories and modifications" on
page 7).
5. Ensure an adequate cable cross-section for the pri-
mary and secondary circuits (
Application Report).
6. Use only ROPEX impulse transformers or transfor-
mers approved by ROPEX. Please note the power,
the duty cycle and the primary and secondary
voltages (
Application Report).

Installation procedure
Proceed as follows to install the CIRUS temperature
controller UPT-640 (as of SW 100):
1. Switch off the line voltage and verify the safe isola-
tion from the supply.
2. The supply voltage specified on the nameplate of
the CIRUS temperature controller must be identical
to the line voltage that is present in the plant or
machine. The line frequency is automatically
detected by the temperature controller in the range
from 47Hz to 63Hz.
3. Install the CIRUS temperature controller in the front
panel cutout. It is fastened by means of two clips
which snap onto the side of the controller housing.
4. Wire the system in accordance with the instructions
in section 7.3 "Power supply" on page 13,
section 7.6 "Wiring diagram (standard)" on page 15
and the ROPEX Application Report. The information
provided in section 7.1 "Installation steps" on
page 12 must be heeded additionally.
Check the tightness of all the system connec-
tions, including the terminals for the winding
wires on the impulse transformer.
5. Make sure that the wiring conforms to the relevant
national and international installation regulations.
