Special conditions
The devices must be installed in a protected environment in
accordance with the specific conditions on the test certificate.
Pollution degree 3 (in accordance with IEC 60664-1) should
not be exceeded for the macro environment of the device.
The devices are in accordance with IP degree of protection IP
66 / IP 67. If the device is installed properly, this requirement
is met by the housing as standard.
When connected to the power supply / not connected to the
power supply, the electrical circuits must not exceed
overvoltage category III / II.
Overvoltage protection
For the devices, the client must provide an external
overvoltage protection.
It must be ensured that the overvoltage is limited to 140 %
(HART: 63 V DC or Modbus: 42 V DC) of the maximum
operating voltage U
