low range (30 to 100mA) For higher powers the threshold can be increased up to 300mA. In
case that the relay trips, check the leakage current.
REMARK! : In case that the loads are mainly single phase supplying computers, printers, speed
controllers , etc. , the trip threshold of leakage relay must be increased due to the EMI filters
leakage.
6 TROUBLE SHOOTING AND MAINTENENCE.
• Check periodically that the earth leakage relay operates properly. Use the test push button of the
relay.
• Check periodically that the rated power of the TSA is not surpassed because of the addition of
new loads. (Take into account the overload factor due to harmonics)
• If new loads have to be added, take care of the load balance. Split the loads up in the three line
pairs (U2-V2, V2-W2, W2-U2) , see wire diagram.
