Installation using power-through daisy chain
The converter has been designed to allow a converter to utilize power-through to provide the
mains power for a number of converters in a daisy chain.
The maximum current limits for the daisy chain are given below:
• For the HanQ variants the maximum current of the daisy chained converters must not exceed
16 A.
• For the Glanded variants the maximum current on the daisy chained converters must not
exceed 12 A.
• For both HanQ and Glanded variants the input for the daisy chained converters can be
protected by a 20 A fuse.
It is the users responsibility to ensure that the current limits are not exceeded.
The methodology for daisy chaining a number of converter is shown in the following diagram.
