can affect the operation, measurement precision and data communication quality.

• ALWAYS remove plug connectors when inserting wires with a screwdriver.

• Fuse must be connected to the power supply input, in close proximity of the unit.

• Fuses must be of fast type with a maximum rating of 6A.

• Use cables of appropriate temperature range.

• Use adequate cable section, at least 0.75mm

• For the RS-485 connection, use appropriate shielded twisted wire cable.

Communication quality will depend highly on the cable used.

Do not install the unit close to high electromagnetic

noise emitting devices like contactors, high current

busbars, switchmode power supplies and the like.
