Introduction
This version of the IOLAN+ Rack has been designed specifically to operate on a telecoms
compatible 48V DC supply. Please read these instructions carefully before commencing
installation.
The 48-60VDC supply range marked on the equipment is the nominal voltage associated
with the battery circuit of a centralised DC supply system. Higher voltages are only to be
associated with “float” voltages for the charging function.
