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).
