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.
