5AC901.BUPS-01 UPS Battery Unit 24V 2.2Ah for 5AC901.IUPS-01

The 5AC901.BUPS-01 is a 24 V, 2.2 Ah rechargeable battery unit designed for use with the 5AC901.IUPS-01 UPS interface option installed in a compatible industrial PC.

It contains two maintenance-free 12 V VRLA lead-acid batteries connected in series. When combined with the correct UPS interface and connection cable, the battery unit provides temporary backup energy during a mains power interruption.

The backup system gives the connected industrial computer time to save operating data and complete a controlled shutdown. This reduces the risk of corrupted files, incomplete production records and operating-system damage.

This material number identifies only the external battery unit. It does not include the UPS interface, connection cable, industrial PC or primary 24 V DC power supply.

Key Differentiating Features

Required UPS System Components

The battery unit cannot operate as a standalone UPS without the compatible interface and connection cable.

Connection Cable Options

Compatible connection cables are available in several lengths:

• 5CAUPS.0005-01 with 0.5 m length
• 5CAUPS.0010-01 with 1 m length
• 5CAUPS.0013-01 with 1.3 m length
• 5CAUPS.0030-01 with 3 m length

Select the cable according to the distance between the battery mounting position and the industrial PC.

Battery Version Difference

The 5AC901.BUPS-01 is the smaller 2.2 Ah configuration. It must not be treated as a direct replacement for the 4.5 Ah version because each battery unit has a specified matching UPS interface.

Controlled Shutdown Function

During normal operation, the industrial PC receives power from its primary 24 V DC supply while the UPS interface monitors and charges the battery.

When the primary supply fails, the battery provides temporary power through the UPS interface. The computer can then save required data and perform a controlled shutdown before the battery is discharged.

Actual backup time depends on:

• Industrial PC power consumption
• Installed CPU board
• Memory and storage configuration
• USB peripherals
• Expansion cards
• Battery age and condition
• Ambient temperature
• UPS shutdown settings

A fixed backup time should not be stated without testing the complete computer configuration.

Battery Maintenance

The battery is maintenance-free during normal use, but its charge condition and remaining capacity should still be checked periodically.

A battery kept in storage must be recharged at least once every six months. Prolonged storage without charging can cause deep discharge and permanent capacity loss.

The specified service life is up to five years at 20°C. Higher temperatures can reduce battery life.

Replace the unit when backup time becomes insufficient, charging faults occur or the UPS diagnostic system reports degraded battery condition.

Typical Applications

• Industrial PC power-failure protection
• Controlled machine-computer shutdown
• Packaging machinery
• Production data protection
• Industrial HMI systems
• Machine vision computers
• Factory data collection
• Printing machinery
• Process monitoring computers
• Assembly automation
• Material handling systems
• Industrial computer maintenance

Installation and Selection Notes

Use this battery unit only with the specified 5AC901.IUPS-01 interface option. Compatibility with other UPS interfaces should not be assumed.

Install the correct 5CAUPS connection cable between the battery and UPS interface. Verify the required cable length before mounting the battery inside the cabinet.

The permitted operating temperature is 0°C to 40°C. Avoid excessive heat, condensation, conductive dust and direct mechanical vibration.

Do not open or modify the sealed battery housing. Replacement and disposal must follow the applicable regulations for lead-acid batteries.

After installation, verify the charging status and perform a controlled power-failure test. Confirm that the operating system shuts down correctly before the available battery capacity is exhausted.
