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 legislations 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
• Don't expose the device to continuous water sprays or to relative humidity greater than 90%.
Avoid exposure to corrosive or pollutant gases, natural elements, environments where explosives or mixes of flammable gases are
present, dust, strong vibrations or shock, 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 Installation Guide "MCX hardware network specification" 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
• Avoid touching or nearly touching the electronic components fitted on the board to avoid electrostatic discharges
• The product is not suitable to be exposed directly to the Internet
