Installation precautions
The performance of the port lightning protector may be affected in the following cases:
• The port lightning protector is installed in reverse direction. Connect the IN end to the outdoor
network cable and the OUT end to the network port on the L1000-A.
• The port lightning protector is not well grounded. After the connection, use the multimeter to
confirm that the ground wire for the protector is as short as possible to ensure its good contact with
the grounding screw of the L1000-A.
• The installed port lighting protectors are not sufficient. If the L1000-A has more than one network
port connected with other devices through cables outdoor, install a lightning protector for each
network port.
Connecting the AC power supply to a power strip
with lightning protection
CAUTION:
Make sure the PE terminal of the power socket has been securely grounded.
If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect the
AC power cord of the L1000-A to the AC power line to protect the L1000-A from being damaged by
lightning strikes.
You can attach the power strip to the rack, workbench, or wall of equipment room.
