4.2.1 OPENING/CLOSING THE HOUSING
Make sure that the mechanical installation of the instruments is done properly and the environment is
suitable to open the housing (the housing should not be opened if there is a chance of dirt or water
entering the housing).
Open the housing from its rear. The rear part of the housing will be connected to the top part of the
housing with two stainless steel wires.
Warning:
When closing the housing make sure the weatherproofing seal is positioned correctly, ensure
the seal is free of any debris and the screws are tightened progressively to 0.4-0.5Nm (3.5-4.5 in-lb).
