• Safety devices shall be tested as described in the maintenance schedule of the instruction
manual to determine that they are in good operating condition.
•Mind the markings and information labels on the unit.
• In the event the safety labels are damaged or destroyed, they must be replaced to ensure
operator safety.
• Keep the work area neat. Lack of order will increase the risk of accidents.
• When working on the unit, wear safety clothing. Depending on the kind of activities these are:
safety glasses, ear protection, safety helmet (including visor), safety gloves, protective clothing,
safety shoes. Do not wear the hair long and loose (protect long hair with a hairnet), or wear
loose clothing or jewellery.
• Take precautions against fire. Keep a fire-extinguisher in the vicinity.
•Warning: The ESS is suitable for use in outdoor areas. Protection against moisture is
equivalent to the class IP54 (splash water protection).
ESS (with earthing pin): Earth the pack of batteries as well as the load properly. During
operation, hazardous voltages can be present at the ESS surroundings. Work on or in the
vicinity of the device is only allowed to be performed by qualified electricians. Before each job
(maintenance and repair) of the ESS, the device must be taken out of service by pressing the
emergency off switch! All consumers and voltage sources (generator, network or similar) must
be removed from the ESS surroundings. Otherwise, the ESS or a connected generator could
automatically start (under certain circumstances). Even routine maintenance may only be
carried out by qualified electricians.
It must therefore be ensured that, during the work on the electrical system, the device is stress-
free, i.e. separated from the generator or mains (AC voltage). Even if the ESS has been
separated from its voltage source (generator or grid), there may still be a dangerous voltage
present at the outputs. To avoid this, the emergency off switch must be pressed. Inputs and
outputs are separated by all Poles. All electrical components are discharged after 30 seconds
and the respective work can then be carried out safely.
If a thunderstorm occurs in the immediate vicinity of the ESS, disconnect all electrical devices
from the ESS and press the emergency off switch or the main switch! Overvoltage hazard!
Cleaning with steam radiators, high pressure cleaners, hard water jet or similar devices is not
allowed.
1.3 Safety during transport and installation
To lift a unit, all loose or pivoting parts, e.g. doors, shall first be securely fastened.
Do not attach cables, chains or ropes directly to the lifting eye; apply a crane hook or lifting shackle
meeting local safety regulations. Never allow sharp bends in lifting cables, chains or ropes.
Helicopter lifting is not allowed.
It is strictly forbidden to dwell or stay in the risk zone under a lifted load. Never lift the unit over
people or residential areas. Lifting acceleration and deceleration shall be kept within safe limits.
• In case of transporting a non-trailer unit on a truck, fasten it to the truck by attaching straps
mainly via the marked roof guides and additionally via the fork lift holes, via the holes in the
frame at the front and back or via the lifting beam. To prevent damage, never put straps on the
roof surface of the unit.
• To lift heavy parts, a hoist of ample capacity, tested and approved according to local safety
regulations, shall be used.
