Page 20: Putting Into Operation
Putting into Operation 1. Set variac (23) to position ZERO. 2. Set current range switch (19) to the largest test range. 3. Set operation selection switch (21) to the desired operation mode. 4. Switch on the circuit breaker (29). Now the green pilot lamp (15) lights up indicating that the instrument is ready for operation. -
Page 22: Overcurrent Protection
Overcurrent Protection As soon as overcurrent (e.g. due to shorted HV output) is detected, the circuit breaker (29) blows. The high voltage transformer is immediately disconnected and the HSG 10-1 is switched off. The variac (23) has to be set to Zero position (fully to the left). -
Page 24: Discharging The Cable System
Discharging the Cable System After the test has been finished, the cable capacitance has to be safely discharged and, afterwards, visibly earthed according to VDE 0105. If available, the cable is automatically discharged via the discharge device installed in the test van. Otherwise, a discharge rod with appropriate dimensions has to be used. - Page 25 Tento symbol indikuje, že výrobek nesoucí takovéto označení nelze likvidovat společně s běžným domovním odpadem.
