application concerned during use. The same applies to
the use of accessories.
The signal conditioner is not intended for use as a safety
component. Please also follow the instructions in the "Ad­
ditional safety precautions" section. Proper and safe op­
eration requires proper transportation, correct storage,
siting and mounting, and careful operation.
Operating conditions
S Protect the signal conditioner against direct contact
with water.
S Protect the signal conditioner against moisture and
humidity, as well as weather conditions such as rain
or snow. The signal conditioner protection class is
IP20 (DIN EN 60529).
S Do not expose the signal conditioner to direct sunlight.
S Comply with the maximum permissible ambient tem­
peratures and maximum humidity figures stated in the
specifications.
S The signal conditioner is designed for the CAT II mea­
surement category (measuring circuits directly con­
nected to sockets or similar low-voltage grid installa­
tion connectors), with degree of pollution 2
(non-conductive pollution, temporary conductivity can
occur, as a result of condensation).
S If the signal conditioner is operated outside the mea­
surement category ratings specified in
EN 61010-1:2010 (not connected to the supply net­
work, formerly CAT I), it is necessary to analyze the
operating voltage, the loop impedance, the occasional
overvoltage and the transient overvoltages of the cir­
cuit to be measured. The SCM­HV can only be used
once the analysis data has been compared with the
