2.5.2 Uninterruptible power supply (UPS)
The use of an external uninterruptible power supply (UPS) is recommended to ensure operation
of the controller during a power failure.
The UPS battery capacity is rated according to the SMB Controller's primary power requirements
and the required bridging time. The following table shows the maximum power requirements of
the SMB Controller in its maximum configuration and maximum traffic volume.
The battery capacity required [Ah] can be calculated using the battery voltage and the maximum
bridging time. It is important to note that the battery must never be allowed to become completely
discharged and that in typical conditions only approx. 60% of the maximum power requirements
is needed.
Note:
The uninterrupted operation of the SMB Controller is ensured if the UPS takes over the
power supply within 20ms of the mains outage.
2.5.3 Earthing and protecting the communication server
The protective earth and equipotential bonding are important integral parts of the safety concept:
Standard EN/IEC 62368-1 relevant to safety matters stipulates protective earthing.
