  • Page 50: Commissioning Instructions

    REU 610 Voltage Relay 1MRS755971 Operator's Manual - ANSI Version 5.1. Commissioning instructions Relay commissioning is carried out to confirm correct operation of the relay when it is taken into use. Polarity checking of voltage transformers should be performed to confirm that the wiring circuitry between the voltage transformers and the relay is correct, which is a prerequisite for the protection functions in the relay to operate correctly.

  • Page 51: Relay Verification

    1MRS755971 Voltage Relay REU 610 Operator's Manual - ANSI Version When the plug-in unit is removed from the case, internals of the case must not be touched. Relay case internals may have high voltage potential and touching these may cause personal injury.
