GENERAL WARNINGS

• Every use that is not described in this manual is considered incorrect and is not authorised by the manufacturer
• Verify that the installation and operating conditions of the device respect the ones specified in the manual, specially concerning the supply voltage and environmental conditions
• This device contains live electrical components therefore all the service and maintenance operations must be performed by qualified personnel
• The device can’t be used as a safety device
• Liability for injury or damage caused by the incorrect use of the device lies solely with the user

INSTALLATION WARNINGS

• Mounting position recommended: vertical
• The installation must be executed according the local standards and legislation of the country
• Always operate on the electrical connections with the device disconnected from the main power supply
• Before carrying out any maintenance operations on the device, disconnect all the electrical connections
• For safety reasons the appliance must be fitted inside an electrical panel with no live parts accessible

• Avoid exposure to corrosive or pollutant gases, natural elements, environments where explosives or mixes of flammable gases are present, dust, strong vibrations or chock, large and rapid fluctuations in ambient temperature that in combination with high humidity can condensate, strong magnetic and/or radio interference (e.g. transmitting antennae)
• When connecting loads beware of the maximum current for each relay and connector
• Use cable ends suitable for the corresponding connectors. After tightening the screws of connectors, slightly tug the cables to check their tightness
• Use appropriate data communication cables. Refer to the Fieldbus Installation Guide for the kind of cable to be used and setup recommendations
• Reduce the path of the probe and digital inputs cables as much as possible, and avoid spiral paths enclosing power devices. Separate from inductive loads and power cables to avoid possible electromagnetic noises
