6 Safety regulations and installation notes

• Observe the safety regulations of electrical engineering and industrial safety and liability associations. Disregarding these safety regulations may result in death, serious personal injury or damage to equipment. Direct/indirect contact
• Protection against direct and indirect contact according to VDE 0100 Part 410 must be ensured for all components connected to the system. In the event of an error, parasitic voltages must not occur (single-fault tolerance). Power supply units for power supply
• Provide external protection for the input area (A1/A2).
• Make sure that the power supply unit is able to supply four times the nominal current of the external fuse, to ensure that it trips in the event of an error. Startup, mounting, and modifications Startup, mounting, modifications, and upgrades may only be carried out by an electrically skilled person.
• Before working on the device, disconnect the power.
• Carry out wiring according to the application. Refer to the “Application examples” section for this. Reliable operation is only ensured if the device is installed in housing protected from dust and humidity.
• Install the device in housing protected from dust and humidity (min. IP54). In operation During operation, parts of electrical switching devices carry hazardous voltages.
• Protective covers must not be removed when operating electrical switching devices. For emergency stop applications, automatic startup of the machine can pose serious risks for the user.
• The machine must be prevented from restarting automatically by a higher-level controller. Inductive loads can lead to welded relay contacts.
• Connect a suitable and effective protective circuit to inductive loads.
• Implement the protective circuit parallel to the load and not parallel to the switch contact. Magnetic fields can influence the device. The magnetic field strength of the environment must not exceed 30 A/m.
• Do not use the device in the vicinity of strong magnetic fields (e.g., caused by transformers or magnetic iron). Noise emission may occur when operating relay modules. Wireless reception may be disrupted in residential areas. The device is a Class A product.
• Observe the requirements for noise emission for electrical and electronic equipment (EN 61000-6-4).
• Implement appropriate precautions against noise emission. WARNING: Death, serious personal injury or damage to equipment Depending on the application, incorrect handling of the device may pose serious risks for the user or cause damage to equipment.
• Observe all the safety notes and warning instructions provided in this chapter and elsewhere in this document.

PSR-...-120UC/URM/5X1/2X2 107843_en_01 PHOENIX CONTACT 9 / 16 Faulty devices The devices may be damaged following an error. Correct operation can no longer be ensured.

• In the event of an error, replace the device. Only the manufacturer or their authorized representative may perform the following activities. Otherwise the warranty is invalidated. – Repairs to the device – Opening the housing Taking out of service and disposal
• Dispose of the device in accordance with environmental regulations.
• Make sure that the device can never be reused.

6.1 Safety of mach ines or systems

Draw up and implement a safety concept The machine or system manufacturer and the operator are responsible for the safety of the machine or system and the application in which the machine or system is used. In order to use the device described in this document, you must have drawn up an appropriate safety concept for your machine or system. This includes a risk assessment in accordance with the directives and standards specified in the EC Declaration of Conformity, as well as other standards. Risk assessment, validation and function test

• Before using the device, perform a risk assessment on the machine or system.
• Validate your entire safety system.
• Carry out a new validation every time you make a safety-related modification.
• Perform a function test on a regular basis. Achievable safety integrity Functional safety is guaranteed for the device as a single component. However, this does not guarantee functional safety for the entire machine or system. In order to achieve the desired safety level for the entire machine or system, define the safety requirements for the machine or system as well as how to implement them from both a technological and organizational perspective. The EC Declaration of Conformity can be downloaded for the product at phoenixcontact.net/products.

7 Function description

7.1 One or two-channel activation

The external enable signal of the basic device is connected to A1. The external enable signal can also be switched at A2 as an option.

7.2 Automatic start

The device starts automatically once it has received the external enable signal.

7.3 Safe shutdown

Once the external enable signal has been deactivated, the enabling current paths open and the contacts enter the safe state. When the enabling current paths are open, the device is in the safe state. The confirmation current paths close.

7.4 Diagnostics / proof test

The confirmation current paths transmit safety-related status information. Due to the forced guidance of the contacts, the confirmation current paths close when the enabling current paths open. If required by the application, read one or more confirmation current paths back to the failsafe controller or the basic device. The repeat testing required by standards can be carried out in two ways: 1. Continuity test for the confirmation current path 2. Evaluation of the failsafe controller via readback of the confirmation current path If several devices are used, the N/C contacts of the confirmation current paths can be connected in series.

Only switch 230 V AC at one of the enable contacts if the adjacent contact carries the same potential. Safe isolation/reinforced insulation Reinforced insulation (e.g., thanks to greater air clearances and creepage distances between conductive paths) is designed for one overvoltage category higher than basic insulation.
