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.

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.
