FILTER ELEMENT AS-AIR 2465010 - Caterpillar

High voltage is present. Work on this equipment must be performed by authorized trained personnel. Personnel must be wearing Personal Protective Equipment that meets regulatory requirements to protect the body for the work that is being performed. Failure to use appropriate PPE to protect the body will result in serious personal injury or death.
Before beginning this procedure, ensure that all lockout/tagout procedures for the site are followed to prevent power being applied while the equipment is serviced.Note: The configurations of the UPS systems that are in this section do not have an external System Bypass Cabinet (SBC).Parallel UPS With Common AC Inputs, Normal AC Inputs, and Bypass AC Inputs

Parallel UPS With Common AC Inputs, Normal AC Inputs, and Bypass AC InputsTo access the connections, remove the protection cover (12). Refer to Operation and Maintenance, "Component Description".
Failure to connect the unit to a suitable grounding electrode creates an electrical shock hazard. An electrical shock will result in serious personal injury or death.
The grounding wires must be connected to the grounding plate of each UPS (17) .
Connect the three phases of the bypass AC source to connection (16) in each UPS.
Connect the three phases of the supplied loads to connection (18) in UPS1.
Connect the terminals for load output (18) in UPS2 to the terminals for load output (18) in UPS1 by using the three load wires.
Connect the external battery to connection (17) in UPS1 and to connection (17) in UPS2.
Strap the cables to the frame of the cabinet.
Reinstall the previously removed covers.Parallel UPS With Separate AC Inputs, Normal AC Inputs, and Bypass AC Inputs

Reinstall the previously removed covers.Note: If the two UPS systems are placed beside each other, then use the instructions that are above to wire the systems together. In the other configurations, always make sure of the following: Ensure that the cables between the UPS systems and the bypass AC source have the same cross-section and the same length. These same requirements also apply to the cables between the UPS systems and the load.
