For optimun performance please follow the notes below.
- Remember that it is necessary to install all the electromechanical devices required
to ensure a safety operation of the plant.
- Avoid installation in places with the following features:
- Relative humidity higher than 90% or condensing
- Heavy vibrations or shocks
- Exposures to continuous jets of water
- Exposure to aggressive and polluting environment (eg: sulphurous and ammoniacal
gases, saline mist, smoke) to avoid corrosion and/or oxidation
- High magnetic and/or radio interferences (avoid therefore machine installation near
transmitter aerials)
- Exposure of controllers to direct solar radiation and to atmospheric agents in general.
- It should be remembered that incorrect connection of power supply voltage can
seriously damage the system.When connecting the regulators it is necessary to
follow these instructions:
- Use wire suitable for the used terminals
- Slacken each termination screw and insert the wire terminals, then tighten the screws
- When the procedure has ended, pull the cables slightly to check the correct tightening
- Separate as much as possible the probes and digital input cables from those of
inductive and power loads, to avoid any electromagnetic interferences.
- Never insert in the same channels power cables and probe cables.
