Operating instructions

104
Due to European harmonization and international reconciliation, the standards will be subject to
years of adjustment and renumbering. The detailed schedule therefore contains the current stan-
dards as well, even if the date for their expiry has already been set. There is no product norm for
Thyristor Power Controllers, so that a sensible norm structure must be created from the correspon-
ding basic norms, which ensures safe application and opportunity for comparison.
CAUTION
Thyristor Power Controllers are non-valid devices for disconnection and may therefore be operated
only in connection with a suitable mains isolating device (for instance switch) connected on line side.
Approvals and conformities are available for Thyro-P:
