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.
Note:
Choosing and installing surge arrestors obey to precise technical rules. Distance to equipments 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 decline any liability in regard to damaged caused to equipments not correctly or not sufficiently protected.
3.3.3 Other
Isolation test (Hi-Pot) must not be performed without instructions from the manufacturer.
3.4 Maintenance
The modular 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 on 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.
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.
