Insertion on the IEC EN 60715 rail:
1) Move the two hooks on the back of the module
outwards as illustrated in
.
Pic 2
.
2) Insert the module rear IDC10 connector into a free slot
of DIN rail accessory as you can see in
.
Pic.1
(the insertion is one way only because the connectors are
polarized).
3) To secure the module to the IEC EN 60715 rail,
tighten the two hooks on the side of the IDC10 rear
connector as shown in
.

Removal from IEC EN 60715 rail:
As shown in
:
Pic.2
1) Move outwards the two hooks on the side of the
module, with the help of a screwdriver.
2) Extract the module from the IEC EN 60715 rail.
INSTALLATION ON AND REMOVAL FROM IEC EN 60715 RAIL
In order to ensure optimum performance and a longest working life, the module(s) must be provided
with adequate ventilation and no raceways or other objects that obstruct the ventilation slots.
Never install the modules near heat sources.
We recommend installation in the lower part of the control panel.

Bus Length
DL: Derivation Length
Scheme 1
1) Install the modules on the IEC EN 60715 rail.
2) Connect the remote modules using cables of proper length.
On the table the following data about the cables length are provided:
-Bus Length: Modbus network maximum length as a function of the Baud rate.
It is the length of the cables which connect the two bus terminators modules (see Scheme 1).
-Drop Length: maximum length of a drop line (see Scheme 1).

In order to obtain maximum performances it’s
recommended to use a specific shielded cable, as
an example BELDEN 9841.
