The Waterproof Packing is provided only with the E5CC/E5CC-B.
It is not included with the E5CC-U.
Order the Waterproof Packing separately if it becomes lost or damaged.
The Waterproof Packing can be used to achieve an IP66 degree of protection.
(Deterioration, shrinking, or hardening of the waterproof packing may occur depending on the
operating environment. Therefore, periodic replacement is recommended to ensure the level of
waterproofing specified in IP66. The time for periodic replacement depends on the operating
environment. Be sure to confirm this point at your site.
Consider three years as a rough standard.)
The E5CC-U cannot be waterproofed even if the Waterproof Packing is attached.
