Power supply
Due to the presence of hazardous voltages, the rear metal panel can only be removed by
qualified personnel.
If it is necessary to carry out work on a power supply unit, first disconnect the mains cable from the
system as well as any external EPS48 power connections that may be connected. Then remove the
rear metal panel of the power supply block and disconnect the batteries.
High leakage current
A permanent earth connection is essential before making TRT/TNV-3 telecommunication
network connections.
In the case of a poor earth connection, it is MANDATORY to disconnect the telecommunications
accesses before reconnecting the equipment to earth. It is then necessary to verify that all the
connections have been made correctly.
Before removing any board that provides access to a telecommunications network of
class TRT/TNV-3, make sure you disconnect the links. Reconnect the links once the board is re-
inserted.
