Only authorized and technically trained personnel should handle and install
the power supplies and cables, specifically when access to panels and
switchboards are necessary.
3.2.1. Powering with the AC Power Supply
The TRE25R240 power supply accepts voltage levels from 90 to 264 VAC, with a
maximum input current of 0.7 A. Overcurrent protection and exclusive breakers can be set
by the user if required.
The power supply will be provided either with a fixed or pluggable European plug (CEE 7).
In the case of the pluggable end, the user must connect it to the power supply after
unpacking.
The AC connection must be at a distance equal to or less than 3 linear meters from the
installation of the sensor node. The power supply must be connected to the AC mains, in a
vibration and stress-free environment, stable as possible. The preferred connection points
are wall outlets or secure outlets on the floor. The outlets can also be connected via an
extension cord, as long as the connection end is safe and secure.
The power supply doesn't share the same ingress protection level as the sensor node. The
customer must observe the IP level in order to safely install the power supply.
3.2.2. Powering with DC cable
When using a cable (4x0.25mm² minimum) with an overmolded female M8 4-pin
connector, Figure 4.9, the cable follows the industrial standard, including the pin numbers
and colors. The sensor node accepts from 8 to 48Vdc and the recommended voltage is
24Vdc. The customer must observe that most cables are limited to 30V. The M8 connector
must follow the IEC 61076-2-104 standard with A-coding. The cable construction must be
IP65 or higher, built either with PVC or PUR materials with UL94 rating HB or superior.
3.2.3. Cable Management
The cable is present in both powering alternatives, and it must be securely installed
independently. The customer can install the cable inside distribution trays and ducts. For
external installation, if existing cables (for power or communication) or safe mechanical lines
