SCM-HV
DANGER
The maximum cable length, including the fitted 1 m long
measuring lead, must not exceed 30 m.
It is not acceptable to run cables through outdoor areas.
DANGER
The SCM is designed for CAT II applications. Measure­
ment category II is applicable to test and measuring cir­
cuits that are directly connected to the mains connections
(sockets) of the low­voltage grid installation. The
SCM­HV is not suitable for any other low-voltage grid
installation applications and its use for this purpose is
unacceptable.
DANGER
The following applies to test and measuring circuits with­
out a rated measurement category (not directly con­
nected to the supply network, formerly CAT I): Whether
the SCM­HV is suitable for test or measuring circuit appli­
cations not intended for direct connection to the supply
network, can only be determined by an accurate analysis
of the operating voltage, the peak voltage, the loop im­
pedance, the occasional overvoltage and the transient
overvoltage of these circuits. The following characteris­
tics apply to the SCM­HV in this respect:
S Operating voltage: max. "415 V DC or 415 V rms AC
S Differential voltage: max. "500 V DC or 500 V rms
AC
