Note
Mains cable connection
Mains cable connection with cable glands is allowed for NFPA79 applications only.
Note
For mains wiring: Use cables in copper material, with a conductor temperature rating of at least
65°C.
Note
Terminals 81 and 84 are only to be connected if a special electrode cable with double shielding
is used.
Note
In applications with a risk of low supply voltage below the speci󹪝cations for more than 10
minutes, install an under voltage relay or protection circuit for DC installations.
Note
Output cables
Use shielded cables if long cables are used in noisy environments.
Note
Digital output
If internal resistance of a load exceeds 10 kΩ, connect an external 10 kΩ load resistor in parallel
to this load.
Note
Mains frequency
Select the right mains frequency in parameter 2.1.2 for the mains supply frequency, that you are
using.
For input and output speci󹪝cation refer to Technical speci󹪝cations (Page45).
