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.
