 PRELIMINARY WARNINGS
The word WARNING preceded by the symbol indicates conditions or actions that put the user's safety at
risk. The word ATTENTION preceded by the symbol indicates conditions or actions that might damage the
instrument or the connected equipment. The warranty shall become null and void in the event of improper use or
tampering with the module or devices supplied by the manufacturer as necessary for its correct operation, and if
the instructions contained in this manual are not followed.
WARNING: The full content of this manual must be read before any operation.
The module must only be used by qualified electricians.
Specific documentation is available at www.seneca.it/products/z-lte
The module must be repaired and damaged parts replaced by the Manufacturer. The product is sensitive to
electrostatic discharges. Take appropriate measures during any operation.

Important: Obstructing ventilation slots with any object is prohibited.

Installing the module next to devices that generate heat is prohibited.
Electrical and electronic waste disposal (applicable in the European Union and other countries with recycling).
The symbol on the product or its packaging shows the product must be surrendered to a collection centre
authorized to recycle electrical and electronic waste.
INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life,
adequate ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots.
Avoid mounting modules over heat-generating equipment. Installation in the bottom part of the electrical panel is
recommended.

 ELECTRICAL CONNECTIONS
CAUTION
On first start-up the module must be supplied without any interruptions for at least 72 hours to charge the internal
batteries. Switch the module off with the PS1 button before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc...).

Power supply
Terminals 2 and 3 can be used to provide the module with power supply as an
Aux. volt. 1 alternative to the connection using the Z-PC-DINx bus.
The power supply voltage must remain in the range of either 19 and 40V DC (any
Vac/Vdc 2 polarity), or 19 and 28V AC.
Vac/Vdc 3 The upper limits must not be exceeded as this can seriously damage the module.
If the power supply source is not protected against overload, a safety fuse with a 1 A
max permissible value must be installed in the power supply line.
Serial port 2: RS485 SW2 = OFF
GND 10 Z-LTE has a serial port that can be set with the SW2 switch.
If switch SW2 is in the OFF position, the RS485 COM 2 port is available at terminals
A (+) 11 10-11-12. The illustration shows how to complete connections.
B (-) 12 N.B.: the indication of the RS485 connection polarity is not standardised and in some
devices may be inverted.
Serial port 2: RS232 SW2 = ON
GND 10 Z-LTE has a serial port that can be set with the SW2 switch.
If switch SW2 is in the ON position, the RS232 COM 2 port is available at terminals
RX 11 10-11-12.
TX 12 The illustration shows how to complete connections.
The RS232 interface is fully settable.

PROCEDURE FOR MODULE SWITCH-OFF

The module is equipped with an integrated UPS that allows it to remain on even in the absence of external power.
To turn off the module, first disconnect the external power supply and then press the PS1 button on the right side
of the module for at least 6 seconds.
When the button is released, the PWR LED turns off to indicate that the module is turned off.
