Safety Requirement Standards:
EN61010-1, CAN/CSA C22.2 No. 61010-1-04
• Altitude of installation site: Max. 2000 m above sea
level
• Installation category: I
“Overvoltage category (Installation category)”
describes a number which defines a transient
overvoltage condition. It implies the regulation for
impulse withstand voltage. “ I ” applies to electrical
equipment which is supplied from the circuit when
appropriate transient overvoltage control means
(interfaces) are provided.
• Pollution degree: 2
“Pollution degree” describes the degree to which
a solid, liquid, or gas which deteriorates dielectric
strength or surface resistivity is adhering. “ 2 ” applies
to normal indoor atmosphere. Normally, only non-
conductive pollution occurs. Occasionally, however,
temporary conductivity caused by condensation must
be expected.
