Safety Note

WARNING: The connectors may not be plugged in or disconnected under load. Ignoring the warning or improper use may damage persons and/or property.

WARNING: Commission properly functioning products only. The products must be regularly inspected for damage. Decommission defective products immediately. Replace damaged products. Repairs are not possible.
WARNING: Only electrically qualified personnel may install and operate the product. They must observe the following safety notes. The qualified personnel must be familiar with the basics of electrical engineering. They must be able to recognize and prevent danger. The relevant symbol on the packaging indicates that only personnel familiar with electrical engineering are allowed to install and operate the product.
The products are suitable for applications in plant, controller, and electrical device engineering.
When operating the connectors in outdoor applications, they must be separately protected against environmental influences.
Assembled products may not be manipulated or improperly opened.
Only use mating connectors that are specified in the technical data of the standards listed (e.g. the ones listed in the product accessories online at phoenixcontact.com/products).
When using the product in direct connection with third-party manufacturers, the user is responsible.
For operating voltages > 50 V AC, conductive connector housings must be grounded.
Ensure that the protective or functional ground has been properly connected.
VDE 0100/1.97 § 411.1.3.2 and DIN EN 60 204/11.98 § 14.1.3 are applicable when combining several circuits in a cable and/or connector.
Only use tools recommended by Phoenix Contact.
The installation notes/Design In documents online on the download page at phoenixcontact.com/products must be observed for this product.
Operate the connector only when it is fully plugged in and interlocked.
Ensure that when laying the cable, the tensile load on the connectors does not exceed the upper limit specified in the standards.
Observe the minimum bending radius of the cable. Lay the cable without twisting it.
The connector warms up in normal operation. Depending on the ambient conditions, the surface of the connector can continue to warm up. In this case, the user is responsible for posting warnings (e.g. DIN EN ISO 13732-1:2008-12).

Drawings

Dimensional Drawing

A diagram showing the dimensions of the connector. Key dimensions include: Overall length: 45.55 mm, Diameter: Ø18.7 mm, and another diameter: Ø19.6 mm. An indicator 'A' points to a specific feature.

Schematic Diagram

A circular schematic diagram illustrating the pin assignment of the connector. Pins are labeled with numbers 1, 2, 3 and letters A, B, C, D, E, and PE (Protective Earth).

Diagram: Current vs. Temperature

A line graph displays the relationship between current (I) in Amperes [A] on the y-axis and ambient temperature (ϑ) in degrees Celsius [°C] on the x-axis. The graph shows a derating curve where the maximum current decreases as the temperature increases. A specific configuration is noted: "● = 3x1.0 + 2x0.5 mm²". The legend indicates: "I = current strength, ϑ = ambient temperature, 3x 14 A + 2x 2 A constant."
