2. SAFETY INSTRUCTIONS
A. Keep this instruction booklet where it can always be easily consulted by
the operator or by maintenance personnel.
B. Before making an intervention or connection of any kind, make sure that
the mains are disconnected both from the instrument and from any
device connected to it.
C. Warning: hot components may be inside the plastic housing of the
controller.
D. No user-serviceable parts are inside the plastic housing of the controller.
E. The controller and any device connected to it must be installed in
compliance with the safety regulations in force. If these regulations are
not complied with during installation, and if our product is not installed in
compliance with the indications given in this instruction booklet, then this
may result in the safety of the controller being comprimised. In
particular, the ambient operating conditions for the controller given in our
technical data must be complied with. Absolutely avoid: water
condensation or excessive humidity, exposure to steam, corrosive or
toxic gases, contact with any type of liquid, and exposure to shocks or
extreme vibrations. Not complying with the above indications could
cause malfunctions and entail unpredictable consequences.
F. This controller is guaranteed by Honeywell to have a specific immunity
level, in compliance with CE regulations, against irradiated and
conducted electromagnetic disturbances. By irradiated electromagnetic
disturbances we recommend to screen the controller with a metal screen
connected to ground. To eliminate, or at least reduce conducted
disturbances, which not only could propagate through the mains but also
through the probes or the connected loads, carry out the electrical wiring
according to the indications given in this instruction booklet. If
necessary, use filters with suitable characteristics for specific
applications and for the detected type of disturbance.
G. If the type of probe to be used will directly touch foodstuffs, make sure
that it is in compliance with the local sanitary and health regulations.
H. The controller has no type of protection for the connected loads, so
these must be protected against short circuits, over-current or over-
voltage, excessive temperature, etc., by suitable protective means (such
as fuses, suitable thermo-magnetic circuit breakers, thermal protections,
etc.). At any rate, the electrical power lines that supply both the
controller and any other device connected to it, either directly or through
a transformer, must be manufactured in compliance with the regulations
in force.
I. When the controller is used in appliances where any malfunction of said
controller could cause a form of risk to persons, animals or objects, it is
ABSOLUTELY MANDATORY to provide a suitable protective/safety
device, in addition to the controller, which independently starts to
operate in case of a failure.
J. The controller cannot be used as critical component in life-support
devices or systems without a written approval expressly issued by the
legal representative of Honeywell.
CAUTION
Disconnect the power supply before you begin installing the Icon controller.
Do not reconnect the power supply until you have completed installation.
