GENERAL WARNINGS
- Every use that is not described in this manual is considered incorrect and is not authorized by the manufacturer
- Verify that the installation and operating conditions of the device respect those specified in the
manual, especially concerning the supply voltage and environmental conditions
- This device contains live electrical components. All service and maintenance operations must therefore be
performed by qualified personnel
- The device must not 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
- Recommended mounting position: vertical
- Installation must comply with local standards and legislation
- Before working on the electrical connections, disconnect the device from the main power supply
- Before carrying out any maintenance operations on the device, disconnect all electrical connections
- For safety reasons the appliance must be fitted inside an electrical panel with no live parts accessible
- Do not expose the device to continuous water sprays or to a 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 might cause condensation in combination with high humidity, strong magnetic and/or radio interference
(e.g. transmitting antennae)
- When connecting loads be aware of the maximum current for each relay and connector
- Use cable ends suitable for the corresponding connectors. After tightening connector screws, tug the cables gently
to check their tightness
- Use appropriate data communication cables. Refer to the EKE data sheet for the kind of cable to be used and setup
recommendations
- Minimize the length of probe and digital input cables as much as possible, and avoid spiral routes around 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
PRODUCT WARNINGS
• Use a class II category transformer for 24 V AC power supply.
• Connecting any EKE inputs to mains voltage will permanently damage the controller.
• Battery Backup terminals does not generate power to recharge a device connected.
• Battery backup - the voltage will close the stepper motor valves if the controller loses its supply voltage.
• Do not connect an external power supply to the digital input DI terminals to avoid damaging the controller.
