9.7.9.2 Replacing thyristor electronics
DANGER
Danger when not complying with the five safety rules
Non-observance of the five safety rules can cause death or serious injury. Serious material
damage can also result.
● Observe the five safety rules.
● Work must only be performed on adequately grounded power circuitry.
Two plug connectors are available on the thyristor electronics for connection to the thyristor and
the external circuitry. The mating connector is integrated at the mounting position of the
thyristor electronics.
If the thyristor electronics have to be replaced, proceed as follows:
Disconnecting the cables
To disconnect the cables, proceed as follows:
1. If there are no core end markings, label the two fiber-optic cables and the connected cables.
2. Remove all connecting leads.
3. Detach the two fiber-optic cables from the opto-receiver and opto-transmitter modules.
4. Pull out the fiber-optic cables.
