Note
An HLA module must never be operated directly on a SIMODRIVE monitoring
module, i.e. it must always be connected via a mains infeed module.
For information about connecting further additional SIMODRIVE monitoring
modules in configurations with several HLA modules, please refer to the
Planning Guide for SIMODRIVE 611 Converters /PJU/.
In a multi-tier configuration, all the infeed supply units must be connected
simultaneously.
