Operating Conditions and Temperatures
The SAR is designed to operate at 0°…50° C (32°… 122° F) surrounding air
temperature without derating. The unit must be mounted in a clean, dry location.
Contaminants such as oils, corrosive vapors and abrasive debris must be kept out
of the enclosure. NEMA/UL Type Open, IP20 enclosures are intended for
indoor use primarily to provide a degree of protection against contact with
enclosed equipment. These enclosures offer no protection against airborne
contaminants.
