Step 3: Insert the power cable into the power terminal block according to Table 9 to fix the
power cable.
Step 4: Insert the terminal with the connected cable into the terminal block on the device.
Step 5: Connect one end of the power cable to an external power supply system (with the
allowed power range). If the power LED on the front panel of the switch turns on, the
power supply is connected properly.
Caution:
Before connecting the device to power supply, make sure that the power input meets the power
requirement. If connected to an incorrect power input, the device may be damaged.
Warning:
Do not touch any exposed conducting wire, terminal, or component with a voltage warning
sign, because it may cause personal injury.
Do not remove any part or plug in or out any connector when the device is powered on.
4.8 Alarm Terminal Block
The alarm terminal block is used for alarm output. When the switch works properly, the
normally-open contacts of the alarm relay are closed and the normally-closed contacts are
open. When an alarm occurs, the normally-open contacts are open and the normally-closed
contacts are closed. The alarm is outputted through a 3-pin 5.08mm spacing terminal block,
as shown in Figure 15.
