Installing the casings
1
Note:
The casings are pre-installed
with back covers.
In Earthquake Zone 4, the
maximum number of modules
for stack installations is five.
In Earthquake Zone 4, install
side fixing plates on the casings.
In Earthquake Zone 2, the
maximum allowed height for
a stack is 22U.
2
In pole and wall installations,
the maximum modules per
plinth is two.
In pole and wall installations,
maintenance straps must be
installed in the casings.
M5 X 8 screws should be
secured with thread locking
compound in pole and wall
installations

Side fixing plates for
Earthquake Zone 4
1. Align the holes of the first casing
bottom with the fixing studs
on the plinth
2. Push the casing back until it stops.
3. Attach the casing to the plinth with
M5 X 8 mm screws (6150279).
Tighten to 3.5-4.2 Nm
(2.58-3.10 ft-Ib)
4. Install the remaining casings as
required by the configuration
Check list
Back covers are properly installed.
Fixing screws are tightened.
Optional: In pole and wall installations, maintenance straps are installed in the front covers.
