4.2.7 Power Connection
At start and restart of the RBS, the connection of the RBS power system to the
incoming AC mains and the connection of the users to the DC power in the
RBS depends on the current internal temperature.
When starting or restarting the RBS, actions are first taken to free the internal
surfaces from condensation.
There are a number of startup scenarios, based on the internal temperature at
the moment of startup:
• The internal temperature is within the safe function range.
0 The RBS power system and the user are connected.
• The internal temperature is below the lower limit for safe function low limit.
0
The internal temperature is increased by heating to above the lower limit
for safe function. Then the power system and the users are connected.
• The internal temperature is above the upper limit for safe function.
0
The RBS power system is connected but the users are not. However,
as soon as the internal temperature falls below the upper limit for safe
function, the users are connected.
4.2.8 Power Disconnection
The users are disconnected from the DC power when the internal temperature
falls below the lower limit for safe function.
The users are reconnected to the DC power when the internal temperature has
risen to a temperature which is 5

C above the lower limit for safe function.
