• 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
- 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.
- Don't expose the device to continuous water sprays or to relative humidity greater than 80%.
- 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.
- Avoid touching or nearly touching the electronic components fitted on the board to avoid electrostaticdischarges.
Warnings
• Use a class II category transformer for 24 V AC power supply.
• Do not ground the 24 V AC wires.
• By connecting any EKD 316C inputs to mains voltage will permanently damage the controller.
• Do not apply voltage to the controller before the wiring is completed.
Connection of the terminals to earth will destroy the controller.
