The ThinMux chassis DC power supply feeds must be
connected to either (1) -48 Vdc Safety Extra Low Voltage (SELV)
sources or (2) -48 Vdc sources that are electrically isolated
from the AC sector and reliably connected to earth. The
source’s fault current capacity shall be lower than 50A, or an
appropriate overcurrent protection rated 5A, must be provided
on each -48 Vdc conductor. The overcurrent protection can
also be used as a cutoff switch if another disconnect device is
not installed.
This equipment may be provided with a module that
incorporates laser source(s). Refer to the module’s
documentation for detailed safety information.
The telemetry I/O must be connected to either a SELV source or
an ELV source that is electrically isolated from the AC sector
and reliably connected to earth.
The metallic telecommunication interface should not leave the
building premises unless connected to telecommunication
devices providing primary and secondary protection.
