In this chapter we will cover:
- Requirements for the cables
- Requirements of the power supply
|Never use the AC power! This will void the warranty and bring permanent damage to the electronics. The instrument might be damaged beyond repair.|
2. Overview M12 5-pin connector
Almost all connections are available via the M12 5-pin connector, located on the back of the Transmitter/display.
For use of Ethernet: use M12 4-pin connector, see chapter E4 Ethernet wiring.
The M12 5-pin connector:
|3||4..20 mA. signal, active||Blue|
* Wire colors apply to VPInstruments cables.
3. Cabling details
|For all connections!|
|Use: Shielded twisted pair cabling to avoid any interference from other outside electrical signals.|
|Always: Connect the shield to safety ground at one point. When in doubt, ask an expert to help with proper grounding and shielding of your installation.|
|Thickness of wires depends on the cable length:|
4. Power supply details
Input voltage: 12 to 24 VDC.
At the connector at least 12 Volt: be aware of the voltage drops over long cables!
The Transmitter/display will notify you when there is insufficient power:
5. Next step
Your communication protocol defines the type of wiring you will need.
|For RS485 communication go to ED2. RS485 Wiring|
|For analog output and communication go to E3. Analog output|
|Ethernet communication go to E4. Ethernet wiring|
|For only short-term measurement go to E5. Wiring for air audits|
