1.4 Regulatory Compliance
Safety: EN61010-1
UL 61010-1
CAN/CSA C22.2 No.61010-1
EMC: EN61326-1 Class A, Table 2 (For use in industrial locations)
EN61326-2-3
AS/NZS CISPR11
Korea Electromagnetic Conformity Standard
Installation altitude: 2000 m or less
Category based on IEC 61010: I (Note 1)
Pollution degree based on IEC 61010: 2 (Note 2)
Note 1: Installation category, called over-voltage category, specifies impulse withstand voltage.
Equipment with “Category I” (ex. two-wire transmitter) is used for connection to circuits in which measures are taken
to limit transient over-voltages to an appropriately low level.
Note 2: Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which may reduce
dielectric strength. Degree 2 is the normal indoor environment.
