3.3.2 Surge and Transients Protection
The mains (AC) supply of the modular inverter system shall be equipped with Lightning surge suppression and
Transient voltage surge suppression suitable for the application. Follow manufacturer’s recommendation for
installation. Selecting a device with an alarm relay for function failure is advised.
All sites with installed Bravo ST units must be equipped with a working lightning surge suppression device in service
and installed close enough to ensure effective protection in accordance with best industry practice.
•
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.
3.3.3 Other
•
Insulation test (Hi-Pot) must not be performed without instructions from the manufacturer. Irreparable damage
may occur.
3.4 Maintenance
•
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 (NEC - NFPA 70).
•
Prior to any work conducted on a system/unit make sure that AC input voltage and DC input voltage are
disconnected.
•
Inverter modules and shelves contain capacitors for filtering and energy storage. Prior to accessing the system/
modules after power down, wait at least 5 minutes to allow capacitors to discharge.
•
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.
•
Some internal components may be deemed hazardous by the local jurisdiction. Ensure all local, state, and
national guidelines are followed prior to disposal of the system or components.
