*1. The C1000H-APS01, however, is "A."
*2. Install inside a metal enclosure.
*3. There are no enclosure requirements for OMRON products. Follow the DNV enclosure requirements specified separately for installation locations of the panel containing the product.

Note 1: The above table lists series names. Ask your OMRON representative for details on specific model numbers.
Note 2: Model certification has not been received for usage on the deck, in the bridge, or in locations subject to strong vibration.

Model certification for the DNV (Det Norske Veritas) was made according to the Environmental Test Specific for Instrument and Automation Equipment Standard for Certification No. 2.4.
