2.5 Power Up the SMB Controller
The SMB Controller is powered as standard with 230 VAC or 115 VAC. To ensure that its
operation is maintained even in the event of a mains outage, an external uninterruptible power
supply (UPS) must be used.
2.5.1 115/230 V power supply
The SMB Controller is powered by the supplied power supply unit. The power supply unit is
connected to the mains using a two-pin standard power cable.
Warning:
Hazard due to heat generation in the event of short-circuits. The mains power supply
connection must be protected with 16 A maximum in countries with 230 V mains power
(for instance in Europe), and with 20 A maximum in countries with 115 V mains power (for
example, in North America).
Also note the following points:
• The mains connector acts as a disconnecting device and must be positioned so that it
is easily accessible.
