CHAPTER 1: GETTING STARTED
As a general rule, terminals labeled “A” should be connected to terminals “-“, and terminals “B” to “+”. The GND terminal
should be connected to the common wire inside the shield, when provided. Otherwise, it should be connected to the shield.
Each relay should also be daisy chained to the next relay in the system. A maximum of 32 relays can be connected in this
manner without exceeding driver capability; for larger systems, additional serial channels must be added. It is also
possible to use commercially available repeaters to increase the number of relays on a single channel. Do not use other
connection configurations.
Lightening strikes and ground surge currents can cause large momentary voltage differences between remote ends of the
communication link. For this reason, surge protection devices are provided internally. To ensure maximum reliability, all
equipment should have similar transient protection devices installed.

To communicate through the F650 rear Ethernet port from a PC, a crossover cable is required. If the connection is
performed through a hub or a switch, a direct Ethernet cable is required.
1.4.3 Faceplate display
All messages are displayed on a 20x4 character LCD display. An optional graphic display is also available. Messages are
displayed in different languages depending on the model and configuration settings.
