Commissioning
C9900-U33210 Version: 2.0
4 Commissioning
In order to use the battery pack, you must first transport and unpack it. You can then install the battery pack
in the control cabinet and connect it to the PC.
4.1 Transport and unpacking
Note the specified transport and storage conditions (see Chapter 7 Technical data [}22]).
The battery pack contains two leak-proof VRLA batteries. The batteries are permanently installed in a
corrosion-resistant stainless steel housing and short-circuit proof with electrical fuse protection.
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts.
Transporting a control cabinet with a built-in battery pack can result in excessive impact on the DIN rail and
the battery pack. Therefore, the transport of the battery pack in the control cabinet is not possible. During
transport the battery pack must therefore be protected from excessive mechanical stress. Appropriate
packaging of the battery pack, in particular the original packaging, can improve the vibration resistance
during transport.
On our original packaging you will find the following sticker:
Fig.3: C9900-U332_shipping label
Use the original packaging for re-transportation to ensure the required labeling of the battery packs by the
sticker.
The battery pack is not regulated for air transport as it meets the requirements of Special Provision - "A67"
according to the International Air Transportation Association (IATA) and the International Civil Aviation
Organization (ICAO).
In addition, the battery pack meets vibration and differential pressure tests in accordance with International
Maritime Dangerous Goods (IMDG) regulations.
Unpacking
Proceed as follows to unpack the battery pack:
1. Check the packaging for transport damage.
2. Remove packaging.
3. Keep the packaging for possible future transport.
4. Check your delivery for completeness by comparing it with your order.
5. Check the contents for visible shipping damage.

4.3 Control cabinet installation
WARNING
Risk of deflagration
A missing or insufficient ventilation of the control cabinet in which the battery pack is mounted can lead to
deflagration in the control cabinet.
• Ensure sufficient ventilation of the control cabinet according to EN 50272-2 (see below).
NOTE
Extreme environmental conditions
Extreme environmental conditions can cause damage to the battery pack.
• Avoid extreme environmental conditions.
• Protect the battery pack from moisture and heat.
Ventilation control cabinet
In the event of a fault or heavy load, hydrogen may leak from the batteries inside the battery pack. Oxygen is
present in the control cabinet. If the hydrogen cannot escape from the control cabinet and the hydrogen
concentration in the control cabinet exceeds a value of 4%vol, an explosive mixture is formed and
deflagration may occur in the control cabinet. To keep the hydrogen concentration in the air low and thus
reduce the risk of deflagration, you must ensure appropriate ventilation of the control cabinet in accordance
with EN 50272-2. You can achieve this through natural ventilation. Equip the control cabinet with openings
for air circulation. Position the openings either on opposite walls or in the same wall at least 2m apart.
Control cabinet installation
The battery pack C9900-U332 is designed for installation in control cabinets of machine and plant
technology. The environmental conditions specified for operation must be observed (see chapter 7 Technical
data [}22]).
If you need the dimensions of the battery pack for mounting, you can get them in chapter 4.2 Dimensions
[}12].
Three different mounting options are available for the C9900-U332 battery pack:
• Vertical via the rear on the DIN rail
• Horizontally via the rear on the DIN rail
• Via the mounting plate on the rear side without DIN rail
As delivered, the battery pack is designed for vertical mounting on the DIN rail. To mount the battery pack
horizontally, you must first convert the mounting latches on the back of the battery pack.
Follow the steps below to convert the mounting notches, as shown in figures 7 and 8:
1. Loosen the screw of the ground connection plate with a 3.0 mm Allen key (section A).
2. Remove the ground connection plate (section B).
3. Remove the screws of the two mounting notches using a 2.5 mm Allen key (section C).
4. Remove the two mounting notches (section D).

Fig.8: C9900-U332_conversion mounting plate
ðYou have converted the mounting notches for horizontal mounting.
Regardless of whether you want to mount the battery pack vertically or horizontally on the DIN rail, you must
proceed in the same way. Two types of DIN rail are commonly used in system engineering:
• TS 35 x 7.5
• TS 35 x 15
A flat DIN rail of type TS 35 x 7.5 is too weak for the battery pack. Accordingly, you may only mount the
battery pack on a DIN rail of type TS 35 x 15.
Mounting on the DIN rail
To mount the battery pack on the DIN rail, follow the steps below shown in Figure 9:
1. Place the battery pack on the DIN rail via the rear side (section A).
2. Tighten the four hexagon socket screws of the mounting notches (section B).
ðYou have installed the battery pack on the DIN rail.

4.4 Connect battery pack
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never plug or unplug the battery pack cable during a thunderstorm.
• Provide protective earthing for handling the battery pack.
NOTE
Incorrect connection procedure
Incorrect procedure when connecting the cable can cause hardware damage.
• Follow the documented procedure for connecting the cable.
• Always connect the cable first and only then switch on the power supply of the connected PC.
After you have mounted the battery pack in the control cabinet, you can connect it to the PC.
Grounding
Potential differences are minimized and electrical currents are diverted to the ground through protective
earthing or potential equalization of electronic devices. This is to prevent dangerous touch voltages and
electromagnetic interference.
Connecting the battery pack
You must connect the battery pack to the PC. For this purpose, there is an 8-pin terminal strip (X101) on the
battery pack housing (see Fig. 11).

Fig.12: C9900-U332_double wire end sleeve
PIN 5 and 6 of the battery pack are available for looping through a 24V power supply to the PC. Accordingly,
you can connect a three-core sheathed cable with plus and minus of the supply voltage as well as protective
earth to the battery pack and then connect the battery pack to the PC with an eight-core sheathed cable.
If the supply voltage fails, the PC draws the voltage from the charged battery pack, which saves the data and
allows the PC to shut down properly.
The intended wiring of the battery pack can be found in the wiring diagram in Figure 13.
