2. Safety instructions
 The modular inverter system/rack can reach hazardous leakage currents. Earthing must be carried out prior energizing the
system. Earthing shall be made according to local regulations.
 Prior any work conducted to a system/unit make sure that AC input voltage and DC input voltage is disconnected.
 Inverter modules and shelves comprise capacitors for filtering and energy storage. Prior to accessing to the system/
modules wait min 5 minutes to allow capacitors to discharge.
 AC and DC circuits shall be terminated with no voltage / power applied.
 Some components and terminals carry high voltage during operation. Contact may result in fatal injury.
 Warning labels must not be removed.
 Never wear metallic objects such as rings, watches, bracelets during installation, service and maintenance of the product.
 Insulated tools must be used at all times when working with live systems.
 When handling the system/units pay attention to sharp edges.
 ESD Strap must be worn when handling PCBs and open units.
 The modular inverter system/rack is not supplied with internal disconnect devises on input nor output.
 The modular inverter rack is a dual input power supply. The complete system shall be wired in a way that both input and
output leads can be made powerless in a single action.
 REG systems can be seen as independent power sources. To comply with local and international safety standards N (output)
and PE shall be bonded.
 EPC system that have no AC input wired and connected to comply with local and international safety standards N (output)
and PE shall be bonded. The bonded between N output and L must be removed once the AC input is being connected.

The safety standard IEC/EN62040-1-1 requires that, in case of output short circuit, the inverter must disconnect in maximum
5 seconds. Parameter can be adjusted on T2S; however, if the parameter is set at a value > 5 seconds, an external protection
must be provided in order that the short circuit protection operates within 5 seconds. Default setting is 60s.
 The equipment must be installed and commissioned by skilled technicians according to instructions in this manual.
 Local regulations must be adhered.
 The manufacturer declines all responsibilities if equipment is not- installed according to -instructions herein -by skilled
technician -according to local safety regulation.
 Warranty does not apply if the product is not installed, used and handled according to the instructions in the manuals.
 CE+T cannot be held responsible for disposal of the Inverter system and therefore the customer must segregate and
dispose the materials which are potentially harmful to the environment, in accordance with the local regulations in force in
the country of installation.
 If the equipment is dismantled, to dispose of the products it consists of, you must stick to the local regulations in force in
the country of destination and in any case avoid causing any kind of pollution.
6 – TSI Bravo – User manual – v7.0

2.1 Handling
 The cabinet shall not be lifted using lifting eyes.
 Remove weight from the cabinet by unplugging the inverters. Mark inverters clearly with shelf and position for correct. This
is especially important in three phase configurations.
 Empty inverter positions must not be left open. Replace with module or cover.
2.2 Surge and transients
The mains (AC) supply of the modular inverter system shall be fitted with suitable Lightning surge suppression and Transient
voltage surge suppression for the application at hand. Manufacturer’s recommendations of installation shall be adhered. It is
advisory to select device with alarm relay for function failure.
Indoor sites are considered to have a working lightning surge suppression device in service.
 Indoor sitesMin Class II
 Outdoor sites Min Class I + Class II or combined Class I+II

3. Twin Sine Innovation
Inverter modules carrying the TSI logo and the EPC mark is a triple port converter (AC in, DC in, AC out). Sinusoidal output
converted from mains or/and DC.
Typical loads
 Resistive load
 Inductive and resistive
 Capacitive and resistive
 Non linear (electronic)
3.1 EPC-mode
Mains input (AC) is by default priority whilst DC works as backup.
Switching time between AC input and DC input is 0ms (source transfer).
Regardless of supply source the output voltage is always conditioned, low THD (sineoidal output).
The BOOST functionality enables 10x Inom for a period of >20ms in the event of down stream failures. The upstream breakers
does not have to be oversized to prevent tripping. The overload capacity is 150% for 15 seconds.
The system efficiency is 94-96%1which reduce the overall energy consumption. When running on backup typical efficiency is >9
1%.
The TSI works according to True Redundant Structure (TRS) that features decentralized logic, redundant communication bus and
three levels of, individually independent, disconnection.
The functionality is all included in every inverter module, running them in parallel provides a modular system with no single point of
failure, always conditioned output, high system efficiency, 0ms source transfer time and controlled down stream clearing capacity.

3.2 On-line EPC
DC is the priority source of supply whilst mains (AC) work as the secondary source of supply.
Switching time between DC input and AC input is 0ms (source transfer).
Regardless of supply source the output voltage is always conditioned, low THD (sinusoidal output) Boost function is enabled
without delay
3.3 Safe mode
Safe mode use DC as primary source of supply while mains (AC) is standby.
Mains (AC) is normally disconnected through internal inlet relay and is only connected when down stream clearance is required
(boost) or DC is unavailable.
The transfer between DC and AC result in transfer time, typical 10ms
3.4 REG-mode
Inverter modules carrying the TSI logo and the REG mark is a traditional converter (DC in, AC out). Sinusoidal output converted
from DC input.
 DC input only.
 The output voltage is always conditioned, low THD (sinusoidal output)
 The overload capacity is 150% for 15 seconds
 The inverter efficiency is >88-91%2.
The TSI works according to True Redundant Structure (TRS) that features decentralized logic, redundant communication bus and
three levels of, individually independent, disconnection.
Isolation test must not be performed without instructions from the manufacturer.
