Please also observe the regulations for accident prevention and the occupational safety, operating and safety regulations. The technical specifications of the Monitoring System 300 must not be exceeded!
If you have ordered the Monitoring System 300 as a PoE model, the power is supplied via Power Over Ethernet (PoE). To do this, connect the remote monitoring unit to a PoE-capable network switch. Follow the instructions of the manufacturer of the PoE switch. The standard model of the Monitoring System 300 has no PoE power supply and requires a 12V DC, 1A power supply (not included in delivery). You can optionally order a suitable external power supply in the online store. Didactum also offers a special power supply unit with 2 redundant voltage inputs on request.
Important note: When installing the floating contacts / dry contacts, pls check whether they are really current-free.
Otherwise the mainboard of the Ethernet-enabled remote monitor can be damaged. Further information on the subject of fault signal relays / dry contacts can be found in the data sheets of the manufacturers of your UPS system, emergency power generator or air conditioning system.
Tip from the technical editor: After installing the two-wire signal cables, use pliers to remove the respective plastic teeth from the associated cover. Then put the covers back on the I / O connections of the system. The respective two-wire I / O signal contact should always be labeled with a sticker. This simplifies later testing and maintenance work. An optional strain relief rail / cable clamp rail available in the Didactum online store prevents faulty cables from being accidentally pulled out during subsequent assembly work.
The networked remote monitoring and control device is mounted on a DIN rail (not included in the scope of delivery). You can see exactly how this works in the figure below.
