Note:
•
for correct assembly, follow the instructions shown in the following
diagram.
•
Important: when assembling, make sure that the frame is securely in
place on all four sides.
•
if needing to remove the frame, use a screwdriver to lever it off in slot C.
•
to access the USB port, open the cover B and lift the rubber cap A
using the tab
•
before closing the cover B again, make sure the rubber cap A is properly
inserted (it must be flush with the outer plastic surface).
•
if needing to cut sheet metal, it is recommended to use laser cutting;
•
the thickness of the sheet metal or the material used to make the
electrical panel must be suitable to ensure safe and stable installation
of the terminal;
•
the tension applied by the screws must not cause deformation of the
sheet metal, so as to not compromise the degree of protection (IP)
shown in the specifications. This degree of protection is guaranteed in
the following conditions: maximum deviation of rectangular opening
from flat surface ≤ 0.3mm, maximum roughness of the surface where
the gasket is applied ≤ 120

4.2 Installation
Environmental conditions
Avoid installing the controller and the terminal in places with:
•
exposure to direct sunlight and to the elements in general;
•
temperature and humidity outside the product operating range (see
chapter 12, “Technical Specifications”);
•
large, rapid fluctuations in room temperature;
•
strong magnetic and/or radio frequency interference (avoid installing
near transmitting antennas);
•
strong vibrations or knocks;
•
presence of explosives or flammable gas mixtures;
•
exposure to aggressive and polluting atmospheres (e.g. sulphur and
ammonia vapours, salt mist, fumes) that can cause corrosion and/or
oxidation;
•
exposure to dust (formation of a corrosive patina with possible
oxidation and reduced insulation);
•
exposure to water.
Positioning the controller inside the electrical panel
Install the controller inside an electrical panel in a position where it
cannot be reached and it is protected from knocks or impact. The
controller should be placed inside the panel in a position where it is
physically separated from power components (solenoids, contactors,
actuators, inverters, etc.) and their respective cables. The ideal solution
is to house these two circuits in two separate cabinets. Proximity to such
devices/cables may cause random malfunctions that are not immediately
evident. The panel casing must allow an adequate flow of cooling air.
Important
:
•
for safety reasons the controller should be installed inside an electrical
panel so that the only accessible parts are the display and the built-in
terminal keypad;
•
install the controller so that the disconnect devices can be used safely
and without hindrance.
•
when laying out the wiring, separate as much as possible the probe
cables, digital input cables and serial line cables from the power cables,
contactors, thermomagnetic devices, in order to avoid electromagnetic
interference;
•
never run power cables and probe signal cables in the same conduits
(including the ones in the electrical panels);
•
for control signals, use shielded cables with twisted wires. If the control
cables have to cross over power cables, the intersections should be as
close as possible to 90 degrees; under no circumstances should the
control cables be laid parallel to the power cables;
•
keep the paths of the probe cables as short as possible and avoid
making spiral paths that enclose power devices;
•
in case of malfunctions do not attempt to repair the device, but
contact a CAREL service centre.

Procedure:
1.
insert the gasket, with the smooth side facing the terminal;
2.
place the terminal in the opening;
3.
tighten the screws;
4.
apply the frame, applying uniform pressure firstly on the 4 corners
(points D) and then on the middle points of the frame (points E), until
it clicks into place.
