A Power supply of 24 V DC for the coupling unit and for the Smart-Wire-DT
slave electronics is needed at the connection POW.
On the SmartWire-DT gateway, connect the POW and AUX supply
voltages via separate miniature circuit-breakers or fuses:
Miniature circuit-breaker 24 V DC for POW
Cable protection in accordance with DIN VDE 0641 Part 11, IEC/EN
·
60898:
Miniature circuit-breaker 24 V DC rated operational current 3 A; trip
types C or Fuse 3 A, utilization class gL/gG
· Cable protection for cable AWG 24 in accordance with UL 508 und
CSA-22.2 No. 14:
Miniature circuit-breaker 24 V DC rated operational current 3 A; Tripping
characteristics C or Fuse 3 A
If any switching devices are also to be connected, for example via the DIL-
SWD-32-001/002 SmartWire-DT slaves, a 24 V DC supply will also be
required at the AUX power connection. This provides the supply for
activating the contactor coils. This supply must be protected by an
automatic circuit-breaker (3A gG/gl or 3 A miniature circuit-breaker with a Z
characteristic).
If switching devices with an activation power greater than 3 A are
connected, an additional feeder module EU5C-SWD-PF1 or EU5C-SWD-
PF2 must be used.
On the SmartWire-DT gateway, connect the POW and AUX supply
voltages via separate miniature circuit-breakers or fuses:
Miniature circuit-breaker 24 V DC for AUX
· Cable protection in accordance with DIN VDE 0641 Part 11, IEC/EN
60898:
Miniature circuit-breaker 24 V DC rated operational current 3 A; trip type
Z or Fuse 3 A, utilization class gL/gG
· Cable protection for cable AWG 24 in accordance with UL 508 und
CSA-22.2 No. 14:
Miniature circuit-breaker 24 V DC rated operational current 2 A; Tripping
characteristics Z or Fuse 2 A
