Tw o flat cables
Bring the Live, Neutral, and Protective Earth wires to the connectors mounted on the DIN rail.
The other power supply cabling is factory installed.
Cards
The card slot connections depend on the installed cards – refer to the chapters of the card
types. The terminal 1 is the one nearest to the back panel.
Configuration
There are several ways to configure the large field display:
• By using the small display and buttons inside the main enclosure. Using the buttons is
described in chapter User interface.
• Via the RS-232 or RS-485 bus. Available only, if the device is equipped with a serial
communications card. Use the free Mekuwin software.
• Via the POL connector on the input card in slot A. Available only, if the device is NOT
equipped with a serial communications card. Accessing the connector requires opening both
the main enclosure and the electronics unit, which will expose dangerous voltages and must
not be done if the supply voltage is higher than 24 V. Suitable programming cables include
POL-RS232 (for RS-232 port of a PC) and DCS772 (for USB port). Additionally an adapter
POL-3PIN is needed. Use the free Mekuwin software.
