The following provides instructions on connecting the Identity Authority Manager (IdAM).

Note the following warning before you start. The on/off switch does not isolate the device from the power supply and the device needs to be protected according to the following:

  • Always pull out the power plug when you are not using the device or if the device is defective. The power plug must be freely accessible.

  • Connect the device to a protective conductor as described in Connect Protective Conductor.

  • Use a central isolating switch in the case of cabinet installation.

Fault caused by I/O devices

The connection of I/O devices can cause faults in the device. The result may be personal injury or damage to the machine or plant.

Note the following when connecting I/O devices:

  • Read and follow the instructions in the documentation of the I/O devices.

  • Only connect I/O devices which are approved for industrial applications in accordance with EN 61000-6-2 and IEC 61000-6-2.

  • I/O devices that are not hotplug-capable may only be connected after the device has been disconnected from the power supply.

Connect Protective Conductor

The protective conductor connection is needed to protect the IdAM. The protective conductor discharges dangerous currents, triggering a surge protection switch. The protective conductor also improves the discharge of interference generated by external power cables, signal cables or cables for I/O devices to ground.

To connect the protective conductor, the following is required:

  • 1 protective conductor, minimum cross section of 2.5mm2
  • 1 x M4 cable lug

To connect the protective conductor:

  1. Crimp the cable lug onto the protective conductor.
  2. Screw the cable lug onto the protective conductor connection as shown below.
  3. Wire the protective conductor to the protective conductor connection of the control cabinet in which the device is installed.

Internal components of a faulty device may carry dangerous voltages that pose the risk of fire or electrical shock.

  • Always connect the ground conductor before you commission the device.

  • The protective conductor connection on the device must be connected to the protective conductor of the control cabinet or system in which the device is installed.

  • Never operate the device without the protective conductor.

  • Take a faulty device out of service immediately and mark it accordingly.

Connect Network Interfaces 

Connect the three network cables to the following interfaces of the Identity Authority Manager (IdAM):

  1. Device Adapter (DA) interface (default network configuration
  2. Sequence Controller and Administration (SCA) interface (default network configuration
  3. Trust Service Adapter (TSA) interface (default network configuration

Note that this outlines how to connect an example network and may need to be adapted to how your actual network is built.  

Connect Power Terminal

The connection terminal for connecting the power supply is fitted to the device. The connection terminal is designed for cores with a cross-section of between 0.25 mm² and 2.5 mm². Ensure to only connect cores with a cross-section of ≥ 0.5 mm². You can use either semi-rigid or flexible cables and you do not need to use end sleeves

To connect the terminal:

  1. Connect the lines as illustrated below.
  2. Confirm that the connection terminal is positioned correctly as illustrated below.

Connect Power Supply

To connect the power supply:

  1. Insert the terminal at the marked position.
  2. Secure the terminal using the integrated screws.

The device should only be connected to a 24 V DC power supply that meets the requirements of safety (or separated) extra-low voltage (SELV) according to the International Electrotechnical Commission (IEC) international standard publication IEC/EN/DIN EN/UL 60950-1. Additionally, the power supply must fulfill the requirement NEC Class 2 or LPS according to the IEC/EN/DINEN/UL 60950-1.
