4.3.1 External current transformers
When selecting the current transformer, remember that the secondary nominal current must be 1 A or 5 A. The primary
nominal current is determined by the current consumption of the load. Appropriate PACT current transformers can be
found in the Phoenix Contact INTERFACE catalog.
DANGER: Risk of electric shock
Current converters and the devices to be connected to them may only be installed when the system has been
disconnected from the power supply!
Observe the order in which the current transformers are connected when wiring them (direction of current
flow). Primary circuit: K-P1 → L-P2; secondary circuit: k-S1 → I-S2
When the current transformer is operated with an open secondary circuit, hazardous voltages may occur at
the secondary terminal blocks.
4.3.2 Network types
The device is designed for connection to various network types in two, three or four-wire networks with even or uneven
load.
Network type
4NBL
3NBL
4BL
3BL
2BL
1BL
The input circuit of the device must correspond to one of the network types listed.
When measuring by means of transformers, the accuracy is greatly influenced by the quality of the transform-
ers used.
