(AC and DC voltage supply)

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

- All service and maintenance operations must 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

- 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 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)

- Use cable ends suitable for the corresponding connectors. After tightening connector screws, tug the cables gently to check their

tightness

- 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 on the board to avoid electrostatic discharges

• Use a class II power supply.

• Connecting any EKF ports to mains voltage will permanently damage the controller.

• Battery backup terminals do 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.
