3.0 Installation

Remove one of these knockouts in order

to run the communication cables from

the router to the inverters.

Do not remove any these front knock-

outs if the router* is attached to the MPX

(see also Figure 3-4).

* The router and bracket are only used

if inverters are to be parallel stacked.

Conduit Knockouts

Info: Knockouts can be easily removed by tapping the edge with a straight bladed screw-

driver and a hammer, then

twist out with pliers; refer to Figure 3-2. Ensure that no debris

remains inside the MPX after removing the knockouts.

The MPX

comes standard with knockouts for 1/2”, 3/4”, 1”, 1 1/2”, and 2” conduits. Refer to Figure

1 for the location of these conduit knockouts.

Select the appropriate knockout that is closest to

the terminal to which you are running the cable/wire (see Figures 3-1 and 3-3).

Info: Identify and remove whatever MPX knockouts you will need for your installation prior

to attaching the MPX to the MP enclosure. It is much easier to do this now rather than once

the MPX is attached.

a Knockout

Note: The RTR bracket below is shown

mounted on the right side of the MPX. The

bracket can also be mounted on the left side

of the MPX.

Do not attach the RTR bracket to the MPX/

MP enclosure at this time (the bracket will be

attached later in Section 3.1.8).
