Note:
1. Vibration
When using Curtains with a protective height of 605 mm or more, the vibration performance of the applicable sensor is reduced.
Do not use these Curtains in locations that are subject to vibration.
2. Protective height
When using these cases, the protective height of the applicable sensor is reduced.
Check the rating and performance prior to use.
3. Mounting direction
When using Curtains with a protective height of 605 mm or more, some slackness occurs due to the weight of the Curtain.
For this reason, mount these Curtains only in the vertical direction.
