    1. Connection phase or on DC-net 2. Connection ground 3. Switch for selection of 4Hz continuous or 4Hz puls-signal. 4. Indicator-lamp 4Hz on/off 5. Net-connection Technical specifications: Generator: Supply 230 VAC, +10-20%, 45-65 Hz, 4VA Fuse 63mA quick, 5 x 20 mm. Signal out 4Hz max.
  • Page 4 Calibration of the equipment at 4Hz reading before use: Remember : Small current clamps M1 shall be set at: 10A Medium current clamps C173 shall be set at: 1000mV/A Large current clamps D37N shall be set at: 100mV/A The receiver may be used for all those tongs, so in case one wishes, extra clamps may be bought later.

  • Page 6 Use of Elma 4000 in TN- and TT-net: In TN- and TT-net, the use of 4Hz reading principles cannot be applied, because of the zero point being grounded. The system is then used as standard current leakage clamps. 1. Connect the tongs you wish to use to the receiver in the clamps- symbol (blue socket) and COM (black socket).
  • Page 7 Use of Elma 4000 in IT-nets. In IT-nets the generator and the 4Hz-method be used. The generator shall be placed as close to the inlet as possible, and connected to auxiliary voltage via the net-cable, which is included. 1. Connect one power line from green contact on the generator to ground in the installation, and thereafter the power line from red contact (FASE) to random phase in the construction.
  • Page 8 In IT-nets this being done in the same manner as in TN- and TT-nets. Use of Elma 4000 in direct current nets. Elma 4000 also works in DC-nets, and is then being used in the same way as in IT-nets. Just remember, that you here must connect the generator between ground and the circuit (plus or minus), which has the ground- fault.
