• Material: self-extinguishing thermoplastic.
• Protection degree: IP30.
• Electrostatic protection: with shield to be connected to ground.
Electrical
• Accuracy class: ≤ 0.5.
• Performance: ≥ 5 VA.
• Overload: 20 % permanent.
• Insulation: 4 kV between inputs and outputs, 4 kV between shield and
outputs, 4 kV between shield and inputs.
• Frequency: 45…66 Hz.
NOTE: for the primary and secondary voltages of the transformer, see the configuration
parameters of the module, paragraph "Access from the display" on page 189).
