TECHNICAL DATA

• Observe current supply side P1/K, load side P2/L
• Before opening secondary circuit (e.g to replace an instrument), firstly short-circuit secondary winding using jumpers S1/k and S2/I.
• Use class 0,5 for calibrated energy meters
  • Class 1 for display measuring devices and non-calibrated energy meters
  • Class 3 for relays and measuring devices w/o accuracy requirements (crude display)
• Observe load of measurement supply (e.g. 4m 1,5 mm2 Cu conductors need 2,31 VA with 5A secondary current)
