5 INSTALLATION PROCEDURE
The module has been designed for vertical installation on a IEC EN 60715 DIN rail. For optimal
operation and long life, adequate ventilation must be provided. Avoid positioning cable ducts or other
objects that obstruct the ventilation slots. Avoid mounting modules over equipment that general heat.
Installation in the bottom part of the switchboard is recommended.
OMEGA IEC EN 60715 guide installation and removal.
Insertion on IEC EN 60715 guide:
1) Move the two hooks on the back of the module
outward as illustrated in fig. 1b.
2) Put the module on the OMEGA guide.
3) To secure the module to the OMEGA guide, tighten
the two hooks on the side of the IDC10 rear connector
as illustrated in fig. 1a.
Removal from IEC EN 60715 DIN guide:
As illustrated in figure 1b:
1) Move the two side hooks outward
from the module, assisted by a screwdriver.
2) Extract the module from the guide.
6 ELECTRICAL CONNECTIONS
IDC10 rear connector (POWER AND PORT 1)
The illustration indicates the meanings of the
various IDC10 connector pins if signals are to be
directly sent via them.
Module power is available from the rear connector
or via terminals 2 and 3.
Potential Z-PC-DINAL2-17.5 use
If the Z-PC-DINAL1-17.5 accessory is used, signals
can be sent via terminal board. The illustration
shows the meaning of the various terminals and
DIP-switch position, found in all Seneca supports for
DIN IEC EN 60715 guide, not used for the Modbus
network. GNDSHLD: Connection cable signal
protection shield (recommended).

MI00369-3-EN ENGLISH5/8
Power supply
Electrical power connections are available from terminals 2 and 3 and
using the Seneca DIN IEC EN 60715 guide bus.
Power voltage must be between 11 and 40V(any polarity) or
between 19 and 28 V. The upper limits must not be exceeded in
order to avoid serious risk to the module.
The power supply source must be protected from the malfunctions of
the module through appropriately-sized safety fuses.
Serial port 2 - RS485 SW2=OFF
Z-KEY has a serial port that can be set with the SW2 switch. If the
SW2 switch is OFF then terminals:
10-11-12 have the RS485 COM 2 available.
The illustration shows how to complete connections.
Note: the indication of the RS485 connection polarity is not
standardised and in some devices may be inverted.
Serial port 2 - RS485 SW2=ON
Z-KEY has a serial port that can be set with the SW2 switch. If the
SW2 switch is ON then terminals:
10-11-12 have the RS232 COM 2 available.
The illustration shows how to complete connections.
The RS232 interface is fully settable.
RJ45 Ethernet connector (on front)
Z-KEY has an Ethernet 10/100 port with RJ45 connector on the
module front.
Micro USB port
Z-KEY has a micro USB connector that can be used as a configuration
port via Easy Setup software.
Micro SD card slot
Z-KEY has a micro SD card slot on the side of the case.
To insert the SD card in the corresponding slot, make sure the metal
contacts are facing right (with reference to the illustration).
The SD card can be of any capacity.
PS1 key
The PS1 key is not used in this module.
