User Manual 4 < back to the table of contents > 2.2 Installation of the COM- and DAT-Module 2.2.1 Installing the COM-Module 1. Mount the COM-Module onto a DIN rail. 2. Supply power to the COM-Module via Power over Ethernet (PoE) or through an 8-pin connector. When powered via PoE, the I/Os cannot be used. For more information on the power supply of the COM-Module, refer to Chapter 3.2.1 Power Supply. Note! Currently, only the Eth0 port is available! 2.2.2 Installation of one or more DAT-Modules Up to 16 DAT-Modules can be connected to the COM-Module, regardless of whether the KA or SA variant is used. 1. Mount the KA variant directly onto a KA40 or KA63 main switch from Kraus & Naimer. The SA variant, on the other hand, is designed as a standalone solution and can be installed without a main switch. 2. In the KA variant, power is supplied via the connection terminals of the main switch. Detailed installation information can be found in the following chapters: • 4.3.1 Installation the DAT.PM.063A3P.KA • 4.3.2 Installation of the DAT.PM.063A3P.KA 1 – Single-Phase Operation The SA variant is powered via a 3-pole supply terminal.
