Connecting up the supply voltage
The RFU630
requires a power supply unit with the following characteristics:
Supply voltage (stabilized safety extra-low voltage (SELV) according to the
c
urrently ap-
plicable standard EN 60950-1)
RFU630-13101 (UL-certified):
Use a supply voltage according to SELV (EN 60950-1:2006-04) and LPS (EN 60950-
1:2006-04) or Class 2 (UL 1310).
The power source must be able to provide minimum power of 26 W respectively mini-
mum 1.5 A at DC 18 V.
If the optional CDB650-204 or CDM420-0006 connection module is used:
additional 0.5 W output power when the optional CMC600 parameter cloning module
is also used.
For suitable cable see
Chapter 4.4 Pin assignments and lead color assignments of ca-
Protection of supply cable
To ensure protection against short-circuits or overload in the supply cables from the custom-
er's power system, the lead cross sections used have to be selected and protected
according to the national standards.
The supply voltage is fed via the connection module, please see:
