2. Secure the PE cable.
• Connect the PE cable to the nearest
ground point or the ground bar in
the transformer station.
• To enhance the corrosion resistance
of the ground terminal, you are
advised to apply silica gel or paint on
it after connecting the PE cable.
6.5 Connecting Communications Cables for the Fiber Ring Network
Prepare the fitting bag for optical ring switching which contains the optical modules and optical
jumpers.
1. Insert the optical modules
respectively into the SFP1 and
SFP2 ports of the SmartLogger
until they snap into place. Then
pull the modules back to ensure
that they are connected securely.
Pay attention to the directions of
the optical modules. The label of
the optical module on the SFP1
port faces upwards, whereas the
label of the optical module on
the SFP2 port faces downwards.
2. Connect factory-installed optical
jumpers to the optical modules.
3. Remove the ATB cover.
