2 HEALTH AND SAFETY INFORMATION
2.1 BATTERIES
Warning!
High energy levels are present in this unit. Improper handling of the unit
can lead to short circuiting that can result in serious injury. Exercise care
when working with this unit.
Warning!
To avoid battery thermal runaway, the batteries must be connected to an
external PSU with thermal compensated charging. Furthermore, the
external PSU must shut off the battery system if the temperature
reaches 50°C inside the cabinet.

Doc. No: D000100-INS-03, Rev D Page 6 of 36
Warning!
It is important that every battery is connected with the ventilation tube,
and that the first battery in the chain is plugged. The tube must be routed
out of the cabinet.
There is a risk that explosive gases are accumulated in the cabinet.
Caution!
Improper handling of batteries can result in the batteries short-circuiting,
which can result in serious injury due to high energy levels. Exercise the
necessary care when working with batteries.
Caution!
Batteries can leak electrolyte if improperly handled. Electrolyte in contact
with skin or eyes can cause injury. In the event of electrolyte injuries,
rinse the affected area with water and seek medical attention
immediately. Use protective equipment when replacing batteries.
Caution!
Excessive heat can cause battery casing to soften and warp, potentially
allowing acid to escape. In contact with the skin, acid can cause injury,
and if breathed in, can affect the airways. Use protective equipment
when replacing batteries.

Doc. No: D000100-INS-03, Rev D Page 7 of 36
Caution!
Heavy batteries can cause injuries when lifting incorrectly. Risk of
personal injury.
Caution!
Handling of the batteries in an incorrect way may cause pinching. Risk of
personal injury.
Caution!
Heavy batteries can cause damages to the property when installed
incorrectly.
Warning!
If the SiteStar cabinet is configured without the DCCU it is of vital
importance that the Battery cables are provided with adequate
protection at the site to ensure compliance to national wiring regulations.
Risk of personal injury and property damage.
2.2 ELECTRICAL EQUIPMENT
Installation personnel should exercise care when working on or around
electrical equipment. In addition to this safety information, the specific
safety instructions for all products involved in the installation procedure
should be adhered to.
When work is being done in a power cabinet, the power supply system
must be de-energized. The mains supply and, if applicable, all batteries
must be disconnected.

Doc. No: D000100-INS-03, Rev D Page 8 of 36
Installation personnel must have competence for electrical installation
according to local regulations.
Warning!
High energy levels are present in this unit. Improper handling of the unit
can lead to short circuiting that can result in serious injury. Exercise care
when working with this unit.
2.3 REFRIGERANT
The refrigerant consists of R134a (1,1,1,2 –Tetrafluoroethane), which has
a GWP of 1300. The required service intervals must be followed and
proper care to avoid leakage at service and end of life must be taken.
Hazards
Inhalation of high concentrations may irritate the respiratory tract
and cause drowsiness and dizziness. At very high levels there is a
risk of breathing difficulties.
Skin contact or splashing in the eyes of the liquefied gas may cause
frostbite.
All handling must take place so that inhalation and skin and eye contact is
avoided. Avoid the steam coming into contact with the welding arcs. Avoid
the steam coming into contact with hot surfaces (decomposition). If there
is a suspicion of leakage from the cooling system, ventilate and leave the
place. Call for a competent cooling technician.
In case of fire, the refrigerant, R134a, develops toxic and corrosive gases.
The cabinet must be standing upright for at least 1 hour before starting.
Caution!
The cabinet must be standing upright for at least 1 hour before starting.

Doc. No: D000100-INS-03, Rev D Page 9 of 36
Caution!
Inhalation of high concentrations may irritate the respiratory tract and
cause drowsiness and dizziness. At very high levels there is a risk of
breathing difficulties.
Skin contact or splashing in the eyes of the liquefied gas may cause
frostbite.
2.4 ROHS/WEEE
For information, see document “DOC-081 –End of Life Treatment Plan”
This document is available on request.
2.5 IN CASE OF FIRE
Take care of any injured persons –Call for help –Try to extinguish the fire.
Only use approved fire extinguisher for extinguishing electrical equipment.
After a fire the cabinet insulation might has been damaged. In this case
the cabinet strength will be considerably reduced and can cause the
cabinet to collapse when opening the door.
Warning!
In case of fire, toxic and corrosive gases will be formed.
Caution!
Excessive heat can cause battery casing to soften and warp, potentially
allowing acid to escape. In contact with the skin, acid can cause injury,
and if breathed in, can affect the airways. Use protective equipment
when replacing batteries.

Doc. No: D000100-INS-03, Rev D Page 10 of 36
2.6 DAMAGES
If the cabinet gets a dented area in size of a hand, with a depth of 10 mm,
the cabinet strength is reduced and has to be replaced.
If the door has been warped so much so that it can’t close securely, it has
to be replaced.
