Liebert Power Strips - Manual (Page 2)

When connecting the rack equipment to the Liebert MP Advanced Power Strip’s receptacles, arrange
cables and connections to avoid tangling and crisscrossing the power cables.
For power management purposes, record the receptacle where each piece of equipment is connected.
Receptacles on the Liebert MP Advanced Power Strip have a numerical designation. Liebert MP
Advanced Power Strips with more than one circuit are named with numbers and letters.
When connecting power to the Liebert MP Advanced Power Strip’s receptacles, follow generally
accepted procedures, such as routing the power cables separately from low-voltage communication
and control wires to prevent electromagnetic interference.
