    2.1 General safety instructions Part of the device documentation in addition to this manual is the enclosed "Safety in- structions for Bender products". 2.2 Work activities on electrical installations Only qualified personnel are permitted to carry out the work necessary to install, commission and run a device or system.

  • Page 10: Intended Use

    Safety instructions 2.3 Intended use The RCMS150… devices are suitable for measuring residual currents up to I = 500 mA Δ in a frequency range of DC…2 kHz. The monitored circuit is rated for a voltage of 300 V and a load current of 32 A. If cables with double or reinforced insulation are routed through the measuring current transformers, higher voltages may occur.
