Preparing electrical installation
6.5.1
SELV supply voltage
For commissioning and operation of the LMS5xx, you need:
•
LMS5xx: SELV supply voltage DC 19.2 to 28.8 V according to IEC 60364441
More data
see "Mechanics/electronics", page 88
.
WARNING
Risk of injury due to electric current!
If the supply voltage is produced by a power supply unit, then insufficient electrical
separation between input and output current circuit of the power supply unit may lead
to an electric shock.
■
Only use a power supply unit whose output circuit has safe electrical separation
from the input circuit. For example with a safety transformer in accordance with
EN 61558-1.
