  • Page 4: General Description

    The SA10A must powered with an external AC- or DC- power supply. Environmental SA10A is built in a small metal carry case designed for rough handling in tough outdoor environments. All connections are protected for any possible type of electrical discharges and disturbances. Some of the inputs are even protected against faulty connections up to 300V peak.

  • Page 5: Safety Regulations Important

    Follow local safety regulations for work on high-voltage circuit breakers. To avoid unintentional breaker operation! Never do any work on a circuit breaker unless the control circuits of the breaker are disconnected from the SA10A control outputs or from any other remote control device.

  • Page 6: Ground

    The power supplies for coils and motor must be interlocked to a security circuit that cut the power if the security circuit is open. Read also additional safety regulations presented in sections below. 3.1.1 Safety regulations. 3.2.1 Safety regulations. 3.3.1 Safety regulations. 3.4.1 Safety regulations. www.elcon.se Rev 1 2018-03-21 Go to INDEX.

  • Page 7: Connection Of Sa10A To Mains Power

    2.2 CONNECTION OF SA10A TO MAINS POWE R. The SA10A can be powered from any AC source 100-240V or DC source 100-240 VDC (with a ground connection). When the SA10A is connected to a wall socket, the socket must be a grounded power outlet.

  • Page 8: Connections For Two Or More Breaking Units Per Phase

    There is no difference between connecting a breaker unit with a pre-insertion resistor and connecting a breaker unit without a pre-insertion resistor. Note! The value of the pre-insertion resistor must be in the range 50 - 5000 ohm Figure. 2.3 Connections for a breaking unit with a pre-insertion resistor www.elcon.se Rev 1 2018-03-21 Go to INDEX.

  • Page 9: Connections For A Resistance Measurement Of A Breaking Unit

    Note! If there is a current transformer (CT) in the circuit, the 200A current from SA10A shall if possible be connected so that the 200A measuring current not go through the CT. If that not possible, the secondary windings of the CT must be short circuit and the CT must be demagnetized after done test.

    Connect a reference resistor between output COILS:CLOSE and measuring input AUX:Ul. Connect the pre-insertion resistor between AUX:Ul” and AUX:COM. Connect the breaker coils to the SA10A for a normal CO-operation (not shown in figure 2.5). Note! Do not connect the motor to SA10A. See 3.4.2 Connection of operating coils.

    The Switch Analyzer is a field-test equipment and is constructed to withstand the handling it requires to fulfil its purposes, although the front panel is sensitive for scratches and other marks. The display is the most sensitive point of the SA10A, it will not tolerate harsh management. This should be considered during unpacking and handling of the unit.
