Figure 11. AC PSU and Power Socket
To connect the switch to a power source follow these steps.
• Installation and removal of the unit must be carried out by qualified personnel
only.
• The unit must be connected to an earthed (grounded) outlet to comply with
international safety standards.
• Do not connect the unit to an AC outlet (power supply) without an earth (ground)
connection.
• The appliance coupler (the connector to the unit and not the wall plug) must have
a configuration for mating with an EN 60320/IEC 320 appliance inlet.
• The socket outlet must be near to the unit and easily accessible. You can only
remove power from the unit by disconnecting the power cord from the outlet.
• When connecting this device to a power outlet, connect the field ground lead on
the tri-pole power plug to a valid earth ground line to prevent electrical hazards.
• This unit operates under SELV (Safety Extra Low Voltage) conditions according to
UL 60950-1. The conditions are only maintained if the equipment to which it is
connected also operates under SELV conditions.
Instructions for Connecting to AC Power
Step Action
1 Install one or two AC PSU modules. Slide them into the PSU slots at the rear of the switch until
they click into place. (Push the red release lever to remove a module from the switch.)
2 Plug the appropriate power cord into a grounded, 3-pin, AC power source.
3 Insert the plug on the other end of the power cord directly into the socket on the AC PSU.
4 Check the LED indicators on the PSU and switch front panel as the unit is powered on to verify
that power is being received. If not, recheck the PSU and power cord connections at the AC
supply source and PSU.
5 If you have installed a second PSU, repeat steps 2 to 4.
