9. Secure the PDC to a torque of
45 N·m using a socket wrench.
In the cabinet combination scenario,
the expansion bolts need to be
partially tightened.
Channel Steel Installation
1. Determine the cabinet installation
positions on the channel steels
based on the marking-off template,
as shown in the figure.
1. Huawei does not provide
channel steel or expansion bolts
used for securing channel steel.
It is recommended that the
customer purchase at least 50
mm wide channel steel.
2. Ensure that the distance
between the outer surfaces of
channel steels is 800 mm, and
that the surfaces are flush.
2. Drill mounting holes on the
channel steels using a hammer
drill.
3. Place the cabinet on the
channel steel using a forklift
and align the holes.
4. Adjust the leveling feet of the
PDC using an adjustable wrench
until the leveling feet touch the
channel steel.
In the channel steel installation
scenario, the four leveling feet
need to firmly touch the channel
steel to support the weight of the
cabinet, as shown in the figure.
5. Level the PDC using a level and an adjustable wrench.
Use a measuring tape when leveling the cabinet to ensure that the height between the cabinet
top and the channel steel is 2000±3 mm.
In the cabinet combination scenario, the expansion bolts need to be partially tightened.
6. Use a socket wrench to secure the PDCs.
