INSTALLATION AND ELECTRIC CONNECTIONS
3.1 - Preliminary checks on installation
Before performing installation, check the integrity of the product components,
the adequacy of the model chosen and the suitability of the environment des-
tined for installation:
• Check that all material to be used is in optimal state and suitable for the use
envisioned.
• Check that all conditions for use lie within the product limits of use (para-
graph 3.2)
• Check that all use parameters lie within the limits of the values stated in the
"Product technical features" chapter.
• Check that the place chosen for installation is compatible with the total clear-
ance of the product.
• Check that the surface chosen for the installation of the device is solid and
can guarantee stable fixing.
• Check that the device to be installed is placed in a position where it is pro-
tected from accidental blows.
3.2 - Limits of use for the product
• Check that the product is compatible with the control unit to which it must be
connected; refer to the attached yellow sheet.
• Do not install a number of devices in the plant that exceeds that supported by
the control unit (see respective instruction manual).
• Do not use metal surfaces or surfaces that contain metal for fixing. These
materials absorb a large part of the magnetic field emitted and therefore the
reading distance between the reader and card is reduced to 1-2 centimetres. If
it is not possible to do otherwise, just insert a plastic support material, with min-
imum thickness of 2 cm, between the metal surface and the reader in a way to
obtain a reading distance of about 3-6 cm.
3.3 - Installation and electric connections
Before performing installation, establish the position in which the device will be
fixed and prepare the electric cables necessary for connection to the control
unit. To verify the type of cable to use, refer to the control unit instruction man-
ual (technical features of the cables).
Proceed as follows to perform installation:

ATTENTION! – All connections must be made without the presence of the
electric power input.
01. Remove the front panel (fig. 1);
02. Disconnect the electronic module from the base as shown in fig. 2: use a
screwdriver, press first on one fin ("A" - fig. 1) and then repeat on the oth-
er. ATTENTION! – Do not allow the screwdriver to slip inside the cas-
ing so as not to damage the circuit board;

03. Make holes in the base of the MOMB in the parts prepared for fixing the
screws;
04. Pass the electric cable through the hole and fix the base of the MOMB to
the wall using the screws and plugs supplied;
05. Connect the electric cable to the "Bluebus" clamp (fig. 3);
IMPORTANT – At this point, if several MOMBs are present in the plant (n°
4 maximum), they must be addressed, modifying the position of the elec-
tric jumper; see Ta ble 1. Attention! – The various MOMBs must have dif-
ferent addresses to each other and other control devices present in the
plant;
06. Apply electric power input to the control unit: the MOMB flashes red to
indicate the type of memory present (see Table 3 - chapter 6) followed by 5
flashes if the memory is empty;
07. Perform MOMB learning by the control unit, see the respective instruction
manual "Learning of the bluebus devices";
08. Program the MOMB as described in chapter 4;
After having performed programming it is necessary to check correct function-
ing of the MOMB; see chapter 5 - Inspection.
