Input and Output Connection Requirements

• Any 120V loads must be distributed evenly between X1-X2, X1-X4 and X4-X2. Do not connect
loads between X3-X2 or between X3-X4—these are not standard voltages.
• The single-phase isolation output transformer is a separately derived source. The output Neutral
(X2) is bonded to Ground within the UPS cabinet. No other bonding wire is needed.
• Install a Grounding Electrode Terminal (GET) to the nearest grounding electrode in the building
grounding electrode system. If the grounding electrode conductor must be protected, non-metallic
conduit is recommended. If metal conduit must be used, bond both ends of the conduit to the
grounding electrode conductor. Conduit is not an acceptable grounding electrode conductor.
• The utility may be derived from a single-phase or three-phase source. The line-to-ground voltages
are dependent on the grounding of the utility and do not affect the output voltages. Do not use a
floating AC source.
• With dual input source configuration, both sources are tied together within the UPS cabinet. Two
additional ground screw terminals are supplied for use as needed.
