Description of design of connections
7.1
Connection of protective conductor (PE)
Before the device is placed in operation, a connection must be established between protective
conductor terminal X100/3 and the PE potential of the place of installation.
A flexible PE cable (green/yellow) must be provided with a minimum cross section of
1.5 mm
2
. The cable should be as short as possible (<2 m).
7.2
Connection of voltage supply
The supply voltage is connected to terminals X100/1 (+24V) and X100/2 (M). The cable
length must be less than 30 m. The device is not equipped with a power switch.
The 24 V DC power supply must be adapted to the input data of the device; see data sheet.
7.3
Measuring inputs
The cables connected to the measuring inputs (terminal strips X500, X501, X502, X503,
X600, X601, X602) must be shielded and as short as possible (cable length above 100 m must
be examined regarding measurement uncertainty). Any power or main voltage cables or any
other cable afflicted by interference shall not be lay parallel to the signal lines. Note the
common EMC planning rules.
7.4
Ethernet interface
An 8P8C modular connector or “RJ-45”(X200) is used for connection to an Ethernet cable in
accordance with the specification 100BASE-TX, IEEE 802.3 Clause 25.
7.5
PROFIBUS interface
The transducer is equipped with a 9-pin D-Sub socket (X300) for connection to PROFIBUS.
