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.

Insertion in the DIN rail
As shown in figure:

1. Insert the IDC10 rear connector of the module on a free slot of the DIN rail (the insertion is univocal since the connectors are polarized).
2. To secure the module to the DIN rail, tighten the two hooks on the sides of the IDC10 rear connector.

ATTENTION
These are open-type devices and intended for installation in an end enclosure / panel offering mechanical protection and protection against spread of fire.

USB PORT

• The module is designed to exchange data according to the modes defined by the MODBUS protocol. It has a micro USB connector on the front panel and can be configured using applications and/or software programs.
• The USB serial port uses the following communication parameters: 115200,8,N,1
• The USB communication port responds exactly like the serial ports, with the exception of the communication parameters.
• For more information, visit www.seneca.it/products/z-key-wifi

• Check that the device in question is included in the list of products supported by the Easy Setup APP in the store.

ELECTRICAL CONNECTIONS

Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the Z-PC-DINAL-17.5 accessory.

ATTENTION
Use only copper or copper-clad aluminium or AL-CU or CU-AL conductors

Back connector (IDC 10)
The illustration shows the meanings of the various IDC10 connector pins if signals are to be sent via them directly.

Z-PC-DINAL2-17.5 accessory use
If the Z-PC-DINAL2-17.5 accessory is used, signals can be sent via terminal boards. The illustration shows the meaning of the various terminals and DIP- switch position (found in all supports for the DIN rail listed in Accessories) for the termination of the CAN network (not used for the Modbus network). GNDSHLD:
Connection cable signal protection shield (recommended).

Power supply

• Terminals 2 and 3 can be used to provide the module with power supply as an alternative to the connection using the Z-PC-DINx bus.
• The power supply voltage must remain in the range of either 19 and 40V Vdc (any polarity), or 19 and 28V Vac.
• 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

• Z- KEY WIFI 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 10-11-12. The illustration shows how to complete connections.
• 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

• Z- KEY WIFI 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 10-11-12.
• The illustration shows how to complete connections.
• The RS232 interface is fully settable.

COMMUNICATION PORT IDENTIFICATION

• RJ45 Ethernet port (on front)
  Z-KEY-wifi has an Ethernet 100 port with RJ45 connector on the module front.

• Micro USB port
  Z-KEY-wifi has a USB connector that can be used as a configuration port via the Easy Setup software.

• Micro SD card slot
  Z-KEY-WIFI 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 (as shown in the side figure). The SD card can be of any capacity.

ACCESS POINT: FIRST CONFIGURATION

To activate the first configuration Access Point function, follow the following steps:

1. Press the side button of the Z-KEY-WIFI;
2. Keeping the button pressed, power the instrument;
3. Release the button after 5 seconds.
   Through this procedure, the device switches to first configuration AP mode without password to enter the parameters of the WIFI. The AP led will flash.

OPERATION IN ACCESS POINT MODE

In this mode, a device can function as an Access Point and accept the connection of up to 6 station devices without the aid of an external Access Point.
This configuration can be activated from the web server.

OPERATION IN STATION MODE

In this mode, the device can connect to an existing Access Point. This function can be activated from the web server.

INSTRUMENT CONFIGURATION

• Z-KEY-WIFI can be fully set up via integrated web server.
• The product programming tools can be downloaded free of charge from www.seneca.it, in the Z- KEY-WIFI section.
• To access the configuration, connect with a browser to the maintenance page at the IP address of the Z-KEY-WIFI, for example: http://192.168.90.101 and, when requested, enter the following credentials: Username: admin Password: admin. in the Z-KEY-WIFI section.
• FOR FURTHER INFORMATION, REFER TO THE USER MANUAL available for download at www.seneca.it in the Z-KEY-WIFI section.
