7.1.2

Requirements for connecting cable

The connecting cables provided by the customer must fulfill the following requirements.
Electrical safety
In accordance with applicable federal/national regulations.
Cable specification
• Permitted temperature range: –40 °C (–40 °F) to ³ 80 °C (176 °F); at least ambient temperature
+ 20 K
• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended if using the HART protocol.
• Cable diameter
– Included cable glands: M20 × 1.5 with cable Æ 6 to 12 mm (0.24 to 0.47 in)
– Plug-in spring terminals for wire cross-sections 0.5 to 2.5 mm

Requirements for the supply unit

Supply voltage
An external power supply is required for each output.
Order characteristic for
"Output"
Option C
1) External supply voltage of the power supply unit with load (® ä 21)
Load
0 to 500 W, depending on the external supply voltage of the power supply unit
Calculation of the maximum load
Depending on the supply voltage of the power supply unit (U
line resistance must be observed to ensure adequate terminal voltage at the device. In doing so,
observe the minimum terminal voltage (® ä 21)
