Installation
The SPA is housed in a universal DIN-style case. Its
back panel is equipped with fittings that make it pos-
sible to mount the unit one both G-type and Top Hat
rails.
Figure 16 shows the unit dimensions, including the
sizes for dual- and triple/quad-alarm SPAs.
Mounting
To mount the SPA on Top Hat DIN-rail, seat the upper
extrusion on the unit back panel over the top lip of the
rail and pivot downward until the housing locks into
place.
To mount the unit on G-type rail, seat the extrusion
under the top lip of the rail and again, pivot downward.
When mounting SPAs in multiple unit scenario like a
rack or cabinet, make sure to allow adequate vertical
spacing for pivoting the units.
