General terms and conditions of use for technical documentation
Phoenix Contact reserves the right to alter, correct, and/or improve the technical
documentation and the products described in the technical documentation at its own
discretion and without giving prior notice, insofar as this is reasonable for the user. The
same applies to any technical changes that serve the purpose of technical progress.
The receipt of technical documentation (in particular data sheets, installation instructions,
user manuals, etc.) does not constitute any further duty on the part of Phoenix Contact to
furnish information on alterations to products and/or technical documentation. Any other
agreement shall only apply if expressly confirmed in writing by Phoenix Contact. Please
note that the supplied documentation is product-specific documentation only and that you
are responsible for checking the suitability and intended use of the products in your specific
application, in particular with regard to observing the applicable standards and regulations.
Although Phoenix Contact makes every effort to ensure that the information and content are
accurate, up-to-date, and state-of-the-art, technical inaccuracies and/or printing errors in
the information cannot be ruled out. Phoenix Contact does not offer any guarantees as to

4.1 Mounting
The device is snapped onto a DIN rail in the control cabinet. The mounting position can be
freely selected, but will be determined by the readability of the LCD.
Figure 4-1 Mounting
4.2 Power supply connection
Avoid being in close proximity to systems that can generate electromagnetic interference.
In addition, avoid mechanical vibrations with acceleration rates greater than
1g (9.81 m/s2) at frequencies below 60 Hz.

4.4 Termination resistor
For MODBUS communication, the RS-485 cable must be terminated at both ends of the bus
with a 120 Ωresistor (supplied with the device).
Figure 4-3 Termination resistor
RS-485 termination device: Connect the resistor between terminal blocks 15 and 17.
RS-485 device: No resistor connected between terminal blocks 15 and 17.
4.5 Installation
The device is designed for connection to various network types in two, three or four wire
networks with symmetrical or asymmetrical load. Current measurement must be
implemented using suitable current transformers.
4.5.1 External current transformers
When selecting the current transformer, the secondary nominal current must be 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.
When measuring by means of current transformers, the accuracy is greatly influenced by
the quality of the transformers used.
Operation using voltage transducers is not supported.
DANGER: Risk of electric shock
Only install current transformers and corresponding measuring devices when the power
supply is disconnected.
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.
Do not ground the secondary side of a current transformer in an IT network.
