2.2. Risk of damaging the unit
To ensure that the unit operates correctly, make sure that:
• The unit is correctly installed.
•
The auxiliary power supply voltage indicated on the device: 24 VDC ± 10%.
•
Use a 230 VAC / 24 VDC SOCOMEC power supply (4829 0120) or use a 1 A gG 24 VDC fuse.
•
The 24VDC power supply should be a SELV (safety extra-low voltage).
• The network frequency indicated on the device: 50 to 460 Hz.
•
There is a maximum voltage at the voltage input terminals of 480 VAC phase/phase or 480 VAC phase/neutral or
480 VDC.
•
Always connect ΔIP, TE, TR or TF current sensors using the recommended connection cables and observing the
maximum prescribed currents.
• Only use RJ45 SOCOMEC cables to interconnect the modules via the Digiware bus.
•
During specific checks, disconnect the devices from the network before attempting to insulate or carry out
dielectric testing.
• The devices are designed for indoor use.
•
If the ambient temperature e50°C, the minimum temperature of the copper conductors to connect to
terminals should be +85°C.
Failure to respect these precautions could cause damage to the unit or cause an electrical shock.
2.3. Responsibility
•
Assembly, connection and use must be carried out in accordance with the installation standards currently in force.
• The unit must be installed in accordance with the rules given in this manual.
• Failure to observe the rules for installing this unit may compromise the device's intrinsic safety.
• The unit must be positioned within an installation which complies with the standards currently in force.
• Any cable which needs to be replaced may only be replaced with a cable with the correct rating.
