The following are the system requirements for the HOMEMATIC HMIPW-DRAP:

• The system uses a four-wire bus line for communication of external devices.

• A separate power supply unit is required for the power supply to the Homematic IP Wired system.

• A router with a network and Internet connection is required for setup and configuration.

• Operation and control are done via smartphone (with the latest Android or iOS) and the Homematic IP App.

The HOMEMATIC HMIPW-DRAP supports several bus topologies for flexible configuration:

• Ring topology

• Ring topology with remote lines

• Star topology

• Bus topology

Ring topology:

This mode offers easy installation of fault-tolerant networks. The bus is routed from the HOMEMATIC HMIPW-DRAP, from one device to the next, and finally back to the Access Point, creating a loop. The device checks if data is received at both bus terminals. If a line is interrupted, the bus topology automatically restructures into two independent bus lines, ensuring all devices continue to work.

Two separate buses:

Both bus connections can be operated as two separate bus lines. For example, one bus can be used for devices within the distribution board, and the other can be used for field installation devices (e.g., flush-mounted) or devices in other sub-distribution boards. The HOMEMATIC HMIPW-DRAP automatically transfers data between the two buses in this mode.

Installation may only be carried out by persons with the relevant electrical engineering knowledge and experience. Incorrect installation can endanger your life and the lives of others, and risk serious damage to property. The following specialist knowledge is particularly important:

• The “5 safety rules” to be used:

– Disconnect from mains

– Secure against restart

– Check for absence of voltage

– Earth and short circuit

– Cover or cordon off neighbouring live parts

• Selection of suitable tools, measuring equipment and, if necessary, personal protective equipment.

• Evaluation of measuring results.

• Selection of electrical installation material for safeguarding shut-off conditions.

• IP protection types.

• Installation of electrical installation material.
