Installing the Controller in a 2-Post Rack—Mid-Mount
Caution
The controller weighs 20 lbs (9.1 kg) with both power supplies installed. Two or more people must work
together to install the controller.
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Note
When you use the mid-mount option, you cannot ground the chassis using the chassis grounding pad or
the provided grounding lug. You will need to ground the chassis in a different location on the chassis
(such as the rear bracket mount holes using an M3 screw) using your own grounding lug.
Follow these steps to mount the controller in a 2-post equipment rack:
Step 1
Attach one of the front brackets to the controller using three M4 screws (see
Figure 15
). Follow the same
steps to attach the second bracket to the opposite side.
Note
Only three of the four holes on each bracket are used (top, left, and right).
