Enclosure Rating
Do not continuously impose external force on the joint of the contact block and cover, otherwise IP67 may not be maintained.
IP67 does not ensure that the B7AC is perfectly watertight. Do not use the B7AC underwater.
The case of the B7AC is made of plastic resin. Do not put heavy objects on it.
