Installing HiPath 3800
4.1.7.1.1 Mounting the Main Distribution Frame (MDFU-E)
The MDFU-E main distribution frame should be installed in the direct vicinity of the system
(note length of connection cable) and at eye level.
The packing material contains a drawing that can be used as a drilling template.
Procedure for wall mounting
4.1.7.1.2 Laying the Line Network and Jumpers on the MDFU-E
Jumpers, external line network
Most main distribution frames do not have an external side. You must jumper them to the in-
coming line network (see jumpering duct, Figure 4-36). Use a standard wiring tool for laying the
cable wires.
Surge protector
To divert surge voltage caused by lightning, insert surge protectors on:
● lines that leave the system buildings (outside stations)
● lines > 500 m long
Connect the polarized surge protectors to the plugging locations on the splitting strip described
above (see Figure 4-38).
Step Activity
1. Use the template to drill the holes.
2. Insert the wall anchors and screw in the screws, leaving 5 mm projecting.
3. Remove the housing cover and mount the MDFU-E on the brackets.
4. Tighten the screws through the holes.

Danger
Be sure to connect the main protective earthing terminal on all system cabinets and
all main distribution frames to the grounding point of the electrical building installa-
tion before connecting up the peripherals (for example, potential equalization bus).
