A.3.4 Specification of Insulation Testing, Protection Class and Degree of Protection /
Test Voltage
Test voltage
The TS Adapter II-MODEM can also be operated in TNV-3 systems. The insulating voltage
between the phone end and the processing end is rated at 250 V AC. In routine testing of the
TS Adapter II-MODEM, the reinforced insulation between the phone end and the rest is
tested with 2200 V DC for 1 second in accordance with EN 60950-1, March 2003.
Protection class
Protection class I in accordance with EN 61140 (VDE 0140-1), i.e., the mounting rail or DIN
rail on which the TS Adapter II is installed must be grounded.
Protection against the ingress of foreign matter and water
Degree of protection IP 20 in accordance with IEC 60529, i.e., protection against contact
with standard probes.
There is no protection against the ingress of water.
