1.3 Safety instructions
Writing conventions
CAUTION
• Avoid the described hazard: Otherwise minor or medium bodily injury or property damage will
result.
WARNING
• Avoid the described hazard: Otherwise there is danger from electric voltage that can lead to
death or serious bodily injury.
For your safety
For safe operation and to avoid personal injury and equipment damage through operator error, always
read these instructions, become familiar with the device, and follow all safety instructions on the prod-
uct and in this document, as well as the safety guidelines of Wurm GmbH & Co. KG Elektronische
Systeme. Keep these instructions ready to hand for quick reference and pass them on with the device
if the product is sold. Wurm GmbH & Co. KG Elektronische Systeme accepts no liability in the case
of improper use or use for purposes other than the intended purpose.
WARNING
DANGER TO LIFE FROM ELECTRIC SHOCK AND/OR FIRE!
• Switch off the power to the entire plant when carrying out installation, wiring or removal work.
Otherwise a mains voltage and/or external voltage may still be present even if the control voltage
is switched off.
• The wiring of the device must be carried out only by qualified electricians.
• Use only the correct tools for all work.
• Check all wiring after connection.
• Take note of the maximum loads on all connections.
• Never expose the device to moisture, for example due to condensation or cleaning agents.
• Take the device out of operation if it is faulty or damaged and is therefore compromising safe
operation.
• Do not open the device.
• Do not repair the device yourself. If the device requires repairs, send it in with an exact descrip-
tion of the fault.
CAUTION
ELECTROMAGNETIC INTERFERENCE CAN CAUSE FAULTS!
• Always use shielded data cables and place them far away from power lines.
Target group This manual is intended for "service technician" personnel.
Intended use The ANI-1F3 is a process control module for CO2 refrigeration plants
with rack and gas cooler control.
