3. Warranty and Safety Conditions*
WARNING:
The electronics in the power supply system are designed for an indoor, clean environment.
When installed in a dusty and/or corrosive environment, indoor, it is important to:
•Install an appropriate filter on the enclosure door, or on the room’s air conditioning system.
•Keep the enclosure door closed during operation.
•Replace the filters on a regular basis.
Important Safety Instructions, Save These Instructions.
3.1 Disclaimer
•The manufacturer declines all responsibilities if equipment is not installed, used or operated according to the
instructions herein by skilled technicians according to local regulations.
•Warranty does not apply if the product is not installed, used or handled according to the instructions in the
manual.
3.2 Technical care
•This electric equipment can only be repaired or maintained by a “qualified employee” with adequate training.
Even personnel who are in charge of simple repairs or maintenance are required to have knowledge or
experience related to electrical maintenance.
•Please follow the procedures contained in this Manual, and note all the “DANGER”, “WARNING” AND “NOTICE”
marks contained in this Manual. Warning labels must not be removed.
•Qualified employees are trained to recognize and avoid any dangers that might be present when working on or
near exposed electrical parts.
•Qualified employees know how to lock out and tag out machines so the machines will not accidentally be turned
on and injure employees working on them.
•Qualified employees also know safety related work practices, including those by OSHA and NFPA, as well as
knowing what personal protective equipment should be worn.
•All operators are to be trained to perform the emergency shut-down procedure.
•Never wear metallic objects such as rings, watches, or bracelets during installation, service and maintenance of
the product.
•Maximum operating ambient temperature is 40°C (104°F).
•Insulated tools must be used at all times when working with live systems.
•When handling the system/units pay attention to sharp edges.
•This product is suitable for use in a computer room.
* These instructions are valid for most CE+T Products/Systems. Some points might however not be valid for the product
described in this manual.
Warranty and Safety Conditions

3.3 Installation
•This product is intended to be installed only in restricted access areas as defined by local regulations and in
accordance with the National Electric Code, ANSI/NFPA 70, or equivalent agencies.
•The Inverter System may contain output over current protection in the form of circuit breakers. In addition to
these circuit breakers, the user must observe the recommended upstream and downstream circuit breaker
requirements as defined in this manual.
•Please use extreme caution when accessing circuits that may be at hazardous voltages or energy levels.
•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 de-energized when necessary.
•REG systems and EPC systems that have no AC input wired and connected can be seen as independent power
sources. To comply with local and international safety standards N (input) and PE shall be bonded. The bonded
connection between N (input) and PE must be removed once the AC input is connected.
•AC and DC circuits shall be terminated with no voltage / power applied (de-energized).
•The safety standard IEC/EN62040-1-1 requires that, in the event of an output short circuit, the Inverter must
disconnect in 5 seconds maximum. The parameter can be adjusted on Inview; however, if the parameter is set at
a value > 5 seconds, an external protection must be provided so that the short circuit protection operates within
5 seconds. Default setting is 60 seconds.
•The system is designed for installation within an IP20 environment. When installed in a dusty or humid
environment, appropriate measures (air filtering) must be taken.
•Environment Conditions:
Storage Conditions: -40 to 70°C
Relative Humidity: 95%, non-condensing
Altitude above sea without de-rating: Less than 1500 m
Greater than 1500 m – de-rating at 0.8% per 100 m
•All illustrations in the manual are for general reference, refer to the technical drawing which is received along
with the system for exact information.
3.3.1 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 rebuild. This is especially important in dual or three phase configurations.
•Empty Inverter positions must not be left open. Replace with module or dummy cover.
•Before working on the system, Isolate Uninterrupted Power Supply (UPS) and check for hazardous voltge
between all terminals including the protective earth.
Warranty and Safety Conditions
9 - Bravo 25 - 230 Vac - User manual - v1.0

3.3.2 Surge and transients
The mains (AC) supply of the modular Inverter system shall be fitted with Lightning surge suppression and Transient
voltage surge suppression suitable for the application at hand. Manufacturer’s recommendations of installation shall
be adhered to. Selecting a device with an alarm relay for function failure is advised.
Indoor sites are considered to have a working lightning surge suppression device in service.
•Indoor sites Min Class II.
•Outdoor sites Min Class I + Class II or combined Class I+II. The modular Inverter system/rack can reach
hazardous leakage currents. Grounding must be carried out prior to energizing the system. Grounding shall be
made according to local regulations.
Note:
Choosing and installing surge arrestors must obey to precise technical rules. Distance to equipment to protect, cable
gage and cable routing have significant influence on proper device service.
Some areas are more susceptible to be hit by electrical strikes, especially when altitude increases.
Good earthing is also crucial for surge arrestors to work properly.
CE+T declines any liability in regard to damaged caused to equipment not correctly or not sufficiently protected.
3.3.3 Other
•Insulation test (Hi-Pot) must not be performed without instructions from the manufacturer.
3.4 Maintenance
•The Inverter system/rack can reach hazardous leakage currents. Earthing must be carried out prior to energizing
the system. Earthing shall be made according to local regulations.
•Prior to any work conducted to a system/unit, make sure that AC input voltage and DC input voltage are
disconnected.
•Prior to accessing the system or modules, make sure all source of supply is disconnected.
CAUTION – Risk of electric shock. Capacitors store hazardous energy. Do not remove cover until 5 minutes after
disconnecting all sources of supply.
•Some components and terminals carry high voltage during operation. Contact may result in fatal injury.
3.5 Replacement and Dismantling
•ESD Strap must be worn when handling PCB’s and open units.
•The Inverter system/rack is not supplied with internal disconnect devices on input nor output.
•CE+T cannot be held responsible for disposal of the Inverter system and therefore the customer must segregate
and dispose of 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 its component products, you must comply with the local regulations
in force in the country of destination and in any case avoid causing any kind of pollution.
