1.6 Installation warnings - operating environments and connections
Avoid assembling the boards in environments with the following characteristics:
•
relative humidity greater than 90%;
•
strong vibrations or knocks;
•
exposure to continuous water sprays;
•
exposure to corrosive or pollutant gases (e.g. sulphur or ammonia fumes, saline mist, smoke) so as to avoid corrosion and
oxidisation;
•
strong magnetic and/or radio interference (therefore avoid installing the unit near transmitting antennae);
•
exposure of the pCO compact to direct sunlight or the elements in general;
•
large and rapid fluctuations in ambient temperature;
•
environments where explosives or mixes of flammable gases are present;
•
exposure to dust (formation of corrosive patina with possible oxidation and reduction of insulation).
For connection, the following warnings must be observed:
•
provide a power supply switch in accordance with the local disposal legislation;
•
using a different power supply from the one specified may seriously damage the system;
•
use cable ends suitable for the terminals. Loosen each screw and insert the cable ends, then tighten the screws. When
completed, lightly tug the cables to check that they are tight;
•
separate as much as possible the probe and digital input signal cables from the cables carrying inductive loads and power
cables to avoid possible electromagnetic disturbance. Never run power cables (including the electrical cables) and probe
signal cables in the same conduits. Do not install the probe cables in the immediate vicinity of power devices (contactors,
circuit breakers or similar);
•
reduce the path of the probe cables as much as possible, and avoid spiral paths that enclose power devices;
•
avoid touching or nearly touching the electronic components fitted on the boards, so as to avoid electrostatic discharges
(extremely dangerous) from the operator to the components;
•
separate the power supply to the digital outputs from the power supply to the pCO compact;
•
when tightening the cables to the terminals do not exert excessive pressure on the screwdriver, to avoid damaging the
pCO compact;
•
disconnect the controller from the power supply before performing any maintenance or assembly operations;
•
the controller has to be integrated inside an instrument panel and it has not to be reachable in order to avoid strokes and
impacts;
•
if the device is used in a manner not specified by the manufacturer, the rated protection of the device may be compromised.
•
in case of failure of the control and of optional boards, please only refer to CAREL service;
•
install optional boards and connectors only supplied by CAREL.
1.7 Maintenance
•
Disconnect the device (turn OFF) before accessing inside parts or during maintenance;
•
all service and/or maintenance operations must be performed by specialist and qualified personnel, in accordance with the
safety standards and legislation in force.
