1) With optional SR35-PSU power supply module.
2) Must be supplied by class 2, limited voltage current or protected by a 4A UL 248 listed fuse.
3) Compliant with Annex S of IEC 60947-1:2007 at 24VDC.
4) Not applicable for UL.
5) The safety functions were not evaluated by UL. Listing is accomplished according to requirements of
Standard UL 508 and CSA14-13, general use applications.
6) For models SR35-017 to SR35-192 the main circuit IP20 rating only applies when the finger guards as
supplied are fitted.
7) Transient surge suppression shall be installed on the line side of this equipment and shall be rated 600V
(phase to phase), suitable for overvoltage category III, and shall provide protection for a rated impulse
withstand voltage peak of 6 kV.
