4.1.7.1.2
Laying the Line Network and Jumpers on the MDFU-E
Danger
7
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).
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).
