Series Machinery Protection System:

• Universal AC Power

• High Voltage DC Power Supply

• Low Voltage DC Power Supply

The Universal AC Power Supply and PIM (Power Input Module)

are not compatible with the Legacy 3500 AC Power Supply,

High Voltage AC PIM and Low Voltage AC PIM.

The High Voltage and Low Voltage DC Power Supplies and

PIM(Power Input Module) are NOT compatible with the Legacy

3500 High Voltage and Low Voltage DC Power Supplies and PIMs.

The 3500/15 AC and DC Power Supplies are half-height modules and

must be installed in designated slots on the left side of the rack. The

3500 rack can contain one or two power supplies with any combinations

of AC and DC. Either supply can power a full rack.

When two power supplies are installed in a rack, the one in the lower

slot acts as the primary supply, and the other in the upper slot acts as

the backup supply. If installed, the second supply is the backup for the

primary one.
