1.3 ELECTRICAL INSTALLATION
Do not install the unit close to high electromagnetic noise
emitting devices like contactors, high current busbars,
switchmode power supplies and the like.
Although the unit is protected against electromagnetic disturbance, excessive disturbance
can affect the operation, measurement precision and data communication quality.
• ALWAYS remove plug connectors when inserting wires with a screwdriver.
• Fuses must be connected to the power supply and phase voltage inputs, in close
proximity of the unit.
• Fuses must be of fast type (FF) with a maximum rating of 6A.
• Use cables of appropriate temperature range.
• Use adequate cable section, at least 0.75mm
2
(AWG18).
• Follow national rules for electrical installation.
• Use only the appropriate cable and connector for serial port connection.
