2.3 Installing the 3098 enclosure

In all other cases, please refer to the system installer.
2.3.1 Important Precautions
Take care to observe the precautions listed at the front of this manual (page Cont-3).
The 3098 SG meter is contained inside an IP rated enclosure (which provides thermal insulation) and a mounting system
(consisting of a bracket and feet) to fix the unit in place. Whilst this structure is designed to minimise damage due to
shocks, the box and unit must not be dropped. Dropping of the 3098 either inside or outside its enclosure will damage
the meter.
Contained inside the enclosure are four box feet which, when attached to a vertical wall will hold the housing. A set of
instructions on how to attach these feet is included inside the box. Enclosure dimensions are in Section 2.7.
