Current Measurement / Logging
4. SAFETY
The instrument has been designed to comply with
IEC1010-2-032 Installation Category (Overvoltage
Category) III 600V Pollution degree 2 and
UL 3111-1. The product range conforms with the EEC
Low Voltage Directive 73/23/EEC and 93/68/EEC.
IEC 1010 is a safety standard which has the following
features:
•
Installation categories I to IV relate the maximum
working voltage to overvoltage transients that can
be expected in the measuring environment. For
the LH range of instruments, 600V CATIII, the
maximum expected transients must not exceed
6kV peak.
•
In a pollution degree 2 environment the internal
design of the instrument can cope with transient
conductivities due to condensation.
Safe operation of the instrument is the
responsibility of the operator who must be suitably
qualified and/or authorised.
Users of this equipment and or their employees
are reminded that Health and Safety Legislation
require them to carry out valid risk assessments of
all electrical work so as to identify potential
sources of electrical danger and risk of electrical
injury such as from inadvertent short circuits.
