  • Page 14: Intended Use

    Safety instructions 2.3 Intended use Load current monitor with three measuring channels for monitoring three- phase isolating transformers with currents up to 32/63 A. According to the standards set down for power supplies in medical locations (DIN VDE 0100-710 (VDE 0100-710), ÖVE/ÖNORM E 8007, IEC 60364-7-710), it overload protection of isolating transformers by disconnection is not allowed.

  • Page 15: System Description

    3. System description In buildings and industrial installations, a fault or failure of the power supply involves high costs. In installations which require high fault tolerance and good safety, three-phase isolating transformers should be monitored contin- uously for overload. 3.1 Features Three true r.m.s.
