POWER SUPPLY
In order to satisfy the electromagnetic compliance requirements:
- Use shielded cables for signals transmission.
- Connect the shield to a preferential ground for devices.
- Space the shielded cables from power cables installations.
(transformers, inverters, motors, induction ovens, etc...).
In addition to the IDC10 connector, power supply can
also be supplied by terminals 14 and 15.
NOTA: A minimum 1A safety fuse, delayed, must be
installed in the power supply line near the device.

RS485 COM 2 AND RS485 COM 4 PORTS
Z-PASS2 module has two serial communication
RS485 ports: COM2 and COM4.
COM2 port can be connected through
1-2-3 screw terminals or by rear IDC10 connector.

Please pay atention to the right installation side of the rear IDC10 connector into the Z-PC-
DINAL2-52.5 bus.
In the figure below you can see the meaning of the various pins of the rear IDC10 connector if you
want to provide the signals directly through this connector. The pictures Pic.3 and Pic.4 show, how
to connect powersupply and RS485 COM2 port to the rear IDC10 connector.

Insertion on the IEC EN 60715 DIN 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 BUS accessory as you can see in Pic.1.
ATTENTION: the insertion is one way only because the
connectors are polarized.
3) To secure the module to the IEC EN 60715 DIN rail,
tighten the two hooks on the side of the IDC10 rear
connector as shown in Pic.1.
Removal from IEC EN 60715 DIN 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 DIN rail.

Bus Length
DL: Derivation Length
Scheme 1
1) Install the modules on the DIN rail (max 120).
2) Connect the remote modules using cables of proper length (see Scheme 1).
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).
-Derivation Length (DL): maximum length of a drop line (see Scheme 1).

MODBUS Scheme 1
Bus length DL Baudrate
1200 m 2 m 115 kbps
In order to obtain maximum performances it’s
recommended to use a specific shielded cable.
MODBUS CONNECTION STANDARDS
In order to ensure optimum performance and the best device’s operating life, the module(s) must be
provided with adequate ventilation without raceways or other objects that can obstruct the ventilation
slots. Never install the modules near heat sources.
We recommend installation in the lower part of the control panel.
