10 Maintenance

The PROTECT D. is constructed using modern, low-wearcomponents. Nevertheless, in order to maintain constant availability and operating reliability, it is advisable to make visual checks (of the battery and the vents in particular) at regular intervals (but at least every 6 months).


Always make sure to secure the working area and carefully follow all safety instructions!

10.1Charging the battery

The battery is always charged automatically when connected to the mains power supply, regardless of the operating mode. IMPORTANT: The battery charging module must be activated (presetting, also see Chapter 7.3.6 on pg. 49ff).

The total charging time for the battery after it has been discharged for a long period of time can depend on the number of additional external battery units (see Chapter 2.3).

10.2 Maintenance checks


The following maintenance work should be performed:



Described in

Visual check

6 months

Chapter 10.2.1

Battery/ventilator check

6 months

Chap 10.2.2/10.2.3

10.2.1Visual check

When doing visual checks, be sure to check whether ...

there are any mechanical damages or foreign bodies in the system,

there is any conductive dirt or dust accumulation in the device and

dust accumulation impedes the heat input or heat dissipation.



Before performing the next step, make sure to switch off the voltage supply to the PROTECT D.

If a large amount of dust has accumulated, the device should be carefully cleaned with dry compressed air to allow for better heat exchange.

The time intervals of the visual checks to be performed largely depend on where the devices are installed and the environmental conditions at these locations.

10.2.2Battery check

You can tell whether the batteries are getting older by making regular capacity tests. Every six months, make comparative checks with respect to the bridging time possible by, for example, simulating a power outage. The load should always show close to the same power requirements. If the battery time sinks drastically compared to the previous check, please contact our hotline (see pg. 5).

10.2.3Ventilator check

Check the ventilators regularly for dust accumulation and any noticeably irregular noises. If the vents are clogged, they must be cleaned; if the ventilator appears to be unusually loud or is not operating smoothly, please contact our hotline (see pg. 5).

10.3Battery replacement


A battery can present a risk of electrical shock and can be very dangerous if handled improperly.

The following precautions should be observed before replacing the batteries:

Remove rings, watches and other metal objects.

If the battery replacement kit is damaged in anyway or shows signs of leakage, contact your dealer immediately.

Properly recycle or dispose of used batteries. Do not dispose of batteries in a fire. The batteries may explode.



i The UPS internal batteries are heavy. Use caution when handling the heavy batteries.

The internal batteries are located behind the UPS front cover (behind the LCD control panel). The internal batteries are packaged together as one unit for easier handling.

To replace the batteries in the UPS (use Protect D.1000 picture for reference):

1. Remove the four M6x16 pan-headscrews, see Figure 21.


Fig. 21: Preparatory measures for battery replacement

2.Then unscrew the two centered screws in front panel (2) using a suitable cross-slotscrewdriver (recommended: Phillips PH1).

3.Now reach behind the front panel on the right and the left and pull the UPS approx. 70 mm forward out of the rack (3) so that the silver sticker on the top of the UPS with the safety precautions becomes visible (refer as well to the following fig. 22)

4.Now slide the front panel a few millimeters sideways to the left (4). The lock will be released …

5.… and you can rotate the entire front panel upwards (5). Make sure not to cut the flexible ribbon cable to the LCD display!

Do not use excessive force.


This part stays in the rack!




Fig. 22: Removing the UPS front cover

6.Disconnect the internal battery connector and EBM battery connector. If the EBM cable is not connected to an EBM, unclip the EBM cable and move it to the left out of the way, see Figure 23.

7.Remove and retain the two screws on the battery cover plate, see Figure 23.

Fig. 23: Disconnecting the UPS internal batteries; Removal of the battery cover plate

8.Grasp an edge of the battery cover plate and pull it out gently. Remove and retain the battery cover plate. Figure 23 shows the location of the battery cover plate.

Carefully pull the handle on the battery tray and slide the battery package slowly out onto a flat, stable surface; use two hands to support the battery package, see Figure 24. Pay attention to the weight of the battery system, especially at the more powerful models.


Fig. 24: Pull out the battery pack


i Verify that the replacement batteries have the same rating as the batteries being replaced.

9.Slide the new battery package into the UPS unit. Push the battery package in firmly.

10.Replace the battery cover plate onto the screw mounts, threading the battery connector through the access slot.

11.Now connect the internal battery system by connecting the

two battery connectors (each consisting of a red and a black


connector) with each other: red in red, black in black.


Make sure to press the connectors quickly and


firmly into one another (red in red, black in black).



If you see a small electric arc while doing this, this


is no cause for concern.


If the EBM cable isn´t connected to an EBM, clip the EBM


cable back into its holder on the battery cover plate. See


Figure 23.


12.Finally close the front panel again slowly and carefully following the directions in reversed order. Make sure that you do not pinch any wires. As the last step, don’t forget to lock the front panel into place using the two screws located in the middle. Then push the UPS completely back into the rack and fasten the UPS on the side using the four M6x16 screws that come with it.



Replace the EBM battery

If the UPS will be operated with additional external

battery packs we recommend from technical point of


view to replace all battery systems at the same time.


Replace the EBM battery system same as the UPS


replacement, ensure a proper connection.
