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).
