Laying the Line Network and Setting Jumpers on the MDFU or MDFU-E
Not for U.S.: 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 4-71 = MDFU, Figure 4-72 = MDFU-E). Use
a standard wiring tool for laying the cable wires.
Not for U.S.: Surge protector
To divert surges 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 4-69).

Danger
Connect the system to ground before connecting the stations.
>
If you jumper stations on the MDFU or MDFU-E (for example, with an ICCS network)
without first entering the relocate code, when you reconnect them the stations affect-
ed will go into operation with the data of the stations originally installed.
