2.1 Intended use
The device is a mobile, battery-powered energy supply for electrical consumers that will be operated
off-grid with household or three-phase current.
2.2 Improper use
Any use that deviates from these operating instructions is contrary to the intended use. Use contrary
to the intended purpose may result in malfunctions and damage to property or personal injury.
2.3 Technical features
Due to the specific design of the ecoPowerTrolley, the operation of sensitive loads (e.g. AV devices) as
well as the use of devices with strong repercussions on the AC grid (e.g. due to high starting currents
or reactive power requirements) does not pose a problem.
The ecoPowerTrolley meets the requirements of protection class IP65 and is therefore suitable for
both indoor and outdoor use.
The ecoPowerTrolley complies with the strict limit values for the emission of electromagnetic
interference and its insensitivity to such interference, meaning that it is equally suitable for use in
residential and industrial areas.

Information on ambient temperature and heat dissipation
•Keep the device away from external heat sources (direct sunlight, radiators, fire).
•Ensure that the cooling fins can freely dissipate the waste heat.
•Do not install the device in a container or housing.

Derating operation
In order to extend the battery life and prevent failures, the device automatically switches to derating
mode in extreme operating conditions. In derating mode, the power that can be supplied to the
device during charging or withdrawn during operation is limited.
The triggering factors for derating operation include:
•High battery temperature
•Low battery charge status
The following curves show the derating behavior:

2 Getting to know the device
Operation at high ambient temperatures
The ecoPowerTrolley dissipates the waste heat generated during operation via cooling fins to the
ambient air. Consequently, the attainable cooling capacity is reduced at high ambient temperatures.
If the peak power is removed for a short time, this effect is not significant; otherwise, the following
limitations arise:
•When the maximum output power is removed, the attainable running time is reduced.
•The achievable continuous power is reduced depending on the ambient temperature.
The following curves show the influences of the ambient temperature:
Achievable runtime as a function of ambient temperature at maximum continuous output
Attainable runtime as a function of ambient temperature at maximum continuous output

3.1 General and special safety instructions
Personnel qualification
•No special personnel qualification is required to use the device. The device may be used by any
person who is physically and mentally capable of doing so and who has read and understood
the operating instructions.
•Maintenance and repair work may only be carried out by a qualified electrician.
What are the safety features of the device?
•Protection class II
The design of the device meets the requirements for a device of protection class II by ensuring
the following galvanic isolations:
- between load input and outputs
- between housing and outputs
•Operation of consumers of protection class I
Thanks to the equipotential bonding provided at the outputs, protection class I loads can be
safely operated on the device.
•Limitation of the short circuit current
The internal DC fuse limits the short-circuit current to <500 A (peak).
•Protection in case of insulation faults
In the event of a (single) insulation fault, no body current can flow because the outputs have
no grounding.
•Automatic shutdown in case of ground fault or housing short circuit
If an internal or external ground fault or housing short circuit occurs, the device switches off
immediately.
•Automatic shutdown in case of overload
In the following cases, the device switches off due to overload:
- Exceeding the time limit when drawing the full rated current
- Exceeding the maximum permissible withdrawal current
•Automatic shutdown in case of overheating
Overheating occurs when both values “ambient temperature” and “discharge current” exceed
a limit value over a certain period of time. Then the device switches off.
What additional safety precautions must the user take?
•Comply with legal safety regulations
By connecting several loads to the device, a low-voltage network is created, during the
operation of which legal safety regulations must be observed. Research the regional safety
regulations and implement them under your own responsibility.
•Avoid fault current with several loads connected
In order to prevent personal injury and material damage caused by residual current, it is
recommended to equip each individual additional connected load with a residual current
circuit breaker (RCD type A / 30 mA) when operating more than one connected load. If only
one connected load is connected, no residual current circuit breaker (RCD type A / 30 mA) is
required.
•Limit the line network for connected loads
With the increasing expansion of the line network, the risk of malfunctions and undetected
sources of error, e.g. damaged cables, increases.
- Do not use unnecessary distribution sockets.
- Do not use extension cords or use them as short as possible.
- Make sure that the cables are clearly arranged.
•Maintain operational reliability of the connected consumers
Have the consumers regularly checked for electrical safety by a qualified electrician.
