Note
For transformers on ships, saltwater-proof DIN rails must be used
according to the regulations of Germanic Lloyd. This requirement is fulfilled
by all rail designs.
When selecting the type of connection on safety transformers in acc. with
IEC 742/EN 60742/DIN VDE 0551-1, please observe:
- When safety transformers are used as self-contained devices, only
screw connections are permitted for the external connections.
- When installing safety transformers, the specifications of the respective
devices must be observed.
