Connect the power cord supplied with the switch to the power connector on the back of the
switch, and then into a properly grounded electrical outlet.
Figure 10 Connecting the Power cord
The 3810M switches do not have a power switch. They are powered on when the
power cord is connected to the switch and to a power source. For safety, the power outlet
should be located near the switch installation.
The switch automatically adjusts to any voltage between 100-240 (110–240 for JL087A
power supply) and either 50 or 60 Hz. No voltage range settings are required.
If your installation requires a different power cord than the one supplied with the switch, be
sure to use a power cord displaying the mark of the safety agency that defines the regulations
for power cords in your country. The mark is your assurance that the power cord can be
used safely with the switch.
Check the LEDs on the switch as described below.
