The unit shall only be installed and put into operation by qualified personnel.

This unit is designed for installation in an enclosure and is intended for general use, such as in industrial control,

office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear

equipment, where malfunctioning of the power supply may cause severe personal injury or threaten human life.

DC-UPS

Uninterruptible power supply with DC-Input.

Normal mode

Describes a condition where the battery is charged, the input voltage is in range and the output is

loaded within the allowed limits.

Buffer mode

Describes a condition where the input voltage is below the transfer threshold level, the unit is

running on battery (buffering) and the output is loaded within the allowed limits.

Charging mode

Describes a condition where the battery is being charged, the input voltage is in range and the

output is loaded within the allowed limits.

Inhibit mode

Describes a condition where buffering is disabled on purpose by using the inhibit input of the DC-

UPS. (e.g. for service actions, or to save battery capacity)

Buffer time

Same as the term “hold-up time”.
