CONNECTION INFORMATION & SAFETY INSTRUCTIONS
The guarantee will lapse in case of damage caused by failure to
comply with these operating instructions! We shall not be liable
for any consequent loss! We do not accept liability for personal
injury or damage to property caused by inadequate handling
or non-observance of the safety instructions! The guarantee
will lapse in such cases.
This manual contains additional safety instructions in the func-
tional description. Please note them!
If you notice any damage, the product may not be connected
to mains voltage! Danger of Life!
A riskless operation is impossible if:
• The device has visible damages or doesn't work
• After a long-time storage under unfavourable conditions
• The device is strongly draggled or wet
• After inadequate shipping conditions
• Never use this product in equipment or systems that are
intended to be used under such circumstances that may
affect human life. For applications requiring extremely
high reliability, please contact the manufacturer first.
•
The product may only be used for the applications
described on page 1.
• Electrical installation and putting into service must be
done from qualified personnel.
•
During installation and wiring never work when the
electricity is not cut-off ! Danger of electric shock!
•
Never operate unit without housing.
Danger of electric shock!
•
All ‘PE’ terminals must be connected to ground.
Danger of electric shock!
Without PE the internal noise
filter will not work, faulty indicated values may occur.
• Please note the safety instructions and standards of your
place of installation!
• Before installation: Check the limits of the controller and
the application (see tech. data). Check amongst others:
- Make sure that all wiring has been made in accordance
with the wiring diagram in this manual.
- Supply voltage (is printed on the type label).
- Environmental limits for temperature/humidity.
- Maximum admitted current rate for the relays. Compare
it with the peak start-up currents of the controlled loads
(motors, heaters,etc.).
Outside these limits malfunction or damages may occur.
• Sensor/probe cables must be shielded. Don’t install them
in parallel to high-current cables. Shielding must be
connected to PE at the end close to the controller.
If not, inductive interferences may occur.
• Please note for elongation: The wire gauge is not critical,
but should have 0,5mm² as a minimum.
• Mounting the controller close to power relays is
unfavourable. Strong electro-magnetic interference,
malfunction may occur!
• Take care that the wiring of interface lines meets the
necessary requirements.
Cleaning
The use of a dry, lint-free cloth is sufficient to clean the product.
Never use liquids or acidic fluids! Risk of damage!
