- A circuit breaker for the power supply must be pro- vided. - The circuit breaker must be placed near to the UMG510 and easily accessible. - The circuit breaker must be clearly marked. - Check the supply voltage with the type plate mark- ing before connecting. -
Page 11: Measurement
Installation Three phase auxiliary measurement Measurement Medium and high voltage Potential and current transformers are always re- quired for measurements in medium and high volt- age distribution systems. Special safety regulations have to be observed when using these transformers. Measurement circuits The UMG 510 provides two measurement inputs: one three-phase main measurement and one auxil- iary measurement. -
