Installation
How to install the housing
Align the mounting rails () on the bottom of the housing with the housing mount frame () on the main unit, and fit the housing onto the side of the main unit.
Move the housing to the rear, and push the I/F connector () on the housing in the direction of the arrow into the I/F connector () on the main unit. Also move the lock lever () on the bottom of the housing mount frame in the direction of the arrow (up), and plug the connector all the way in.
In order to prevent the housing from falling, the housing which has been placed on top of the housing mount frame must be immediately inserted all the way into the I/F connector on the main unit by operating the lock lever. If the housing is not inserted all the way in, it may become dislodged or fall down.
Provisionally secure by hand the 2 housing securing bolts () of the housing mount frame () from the bottom surface, and use the supplied Allen key to tighten them up to secure the housing.
If these bolts are not tightened up enough, the housing may become dislodged or fall down and it may not be possible to ensure the prescribed operations and performance. Therefore, tighten up both bolts securely.
One of the housing securing bolts is sticking out: Before tightening
None of the housing securing bolts 
are sticking out: After tightening
