After you connect the AC power cord from the L1000-A to a socket on the power strip, verify that the
green RUN LED on the strip is on and the red LED is off.
If the red LED is on, use a multimeter to check the polarity of the wires in the power socket for wrong
connections. If the zero wire (left) and the live wire (right) are correctly connected, check for missing
grounding connection.
Figure 19 Power strip with lightning protection
(1) Operating LED (green) On means the circuit is operating correctly.
Off means the circuit is damaged.
(2) Grounding/pole detection
LED (red) On indicates a wrong wire connection (the wire is not grounded or the
live line and null line are reversely connected), and you need to check the
power supply line.
(3) Power switch
(4) IEC standard socket
It is used to connect to the power supply in the equipment room through a
power cord.
(5) Overload automatic protector The protector automatically opens the electric circuit when the current
exceeds the threshold and closes the electric circuit when the current
drops below the threshold.
(6) Multifunctional socket It is used to connect the power supply of the L1000-A.
