6 Connecting
6.1 Earthing
Earthing is performed via connector X5, pin 3 “FE” (functional earth) and via the
earthing screw or lug on the rear.
For this, use the included 734-103 Female Connector featuring three CAGE
CLAMP
®
connections. First, open CAGE CLAMP
®
no. 3 using an operating tool,
then insert the conductor (strip length: 7 mm, max. 1.5 mm²) and remove the tool.
Plug the female connector into the X5 connector and then verify that the
clamping connection is secured.
6.2 Connecting Devices
Peripherals are connected electrically by the interfaces on the bottom and left
side.
The ETHERNET interfaces are used to connect to a LAN or to the Internet for
communication with the controller. Crossover or patch cables category 5e can be
used.
The USB 2.0 interfaces can be used to connect a keyboard or mouse as an
alternative input device. Also, up to 2 USB memory devices can be connected.
Because there are a large number of USB devices on the market, no guarantee
can be made about the function of individual devices.
USB devices must be connected before power ON because they are not hot-
pluggable.
Do not use USB devices connected to earth!
USB interface shielding is not earthed directly, rather via interference-
suppression capacitor. Only keyboards, mice and USB memory sticks may be
connected. Do not connect devices that are earthed, e.g., printers, because they
bridge the interference-suppression capacitors and thus interference immunity is
reduced.
Insert microSD memory cards as far into the slot until they click into place. The
slot can be sealed to protect the card.
To remove, press the card further down until the lock releases. The card can then
be removed.
The Service interface has no function in this panel.
For more information about the interfaces, see section “Device Description” >
“Connectors” and “Technical Data”.
