Seneca Z-PASS2-IO Installation Manual page 2

INSTALLATION RULES
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.
MODBUS CONNECTION STANDARDS
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).

USE OF Z-PC-DINAL ACCESSORY
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 .

 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.
