Procedure to Attach the Unit to
the Mounting Bracket
Follow the procedure in Table 6-4 to attach the unit to the mounting
bracket. Refer to Figure 6-6.
For ceiling mount applications, two people must do this

second person installs the unit.
WARNING
Use caution when resting the MicroCell or PicoCell unit
on the hooks of the mounting bracket. Do not leave unit
supported by hooks only.
CAUTION
Table 6-4: Procedure to Attach the Unit to the Mounting Bracket
Step Action
1 Lift the unit using the installation handles and place it on the
mounting bracket by aligning the bracket’s upper arms into
the rectangular cutouts in the heatsink. The unit will need to
be raised up slightly so that the lower bracket flange does not
contact the unit’s lower surface. For a ceiling application, use
caution when resting the PicoCell on the hooks on the
mounting bracket.
2 Use a T30 Torx tamper bit to start, but not tighten, both
screws in the location shown in Figure 6-6.
3 At the bottom of the unit, align the hole in the mounting
bracket with the hole in the unit. Place the pin or
customer–supplied padlock through this hole. Screw pin
together and tighten firmly.
4 Use a T30 Torx tamper bit to torque the two mounting screws
to 5.0 N–M.
5 Use a T30 Torx tamper bit to remove the installation handles.
