10 INSTALLATION, CONNECTION AND ENERGIZATION
This chapter describes the electrical and mechanical installation procedures for the MVW01. The presented guidance and suggestions must
be followed in order to assure the proper inverter operation.
WARNING!
The handling of the MVW01 and its mechanical and electrical installation must be carried out by persons trained and
qualified by WEG.
WARNING!
STORAGE OF THE MVW01 PANEL AND ARMS:
After receiving the equipment, remove the plastic film in order to prevent moisture condensation.
Do not store exposed to sunshine and to temperatures above 40 °C (104 °F).
Store the equipment in a clean, protected place with relative humidity not higher than 80 %.
During all the storage period the conditions mentioned earlier must be satisfied, but when components are stored for
more than one year, measures must be taken to dehumidify the storage location.
When using equipment after a long storage period, verify whether the equipment is free of scratches, dirt, rust and other
damages.
The inverter performance and reliability can be impaired if the inverter or the power arms were stored in an environment
out of the conditions listed previously.
DANGER!
The procedures recommended in this warning have the purpose of protecting the user from death, severe personal injury
and considerable property damage.
Power supply isolating switches: equipment for isolating the inverter power and auxiliary supplies must be planed.
They must cut off the inverter supplies (e.g., during installation maintenance tasks).
This equipment cannot be used as emergency stop mechanism.
Make sure that the power supply is disconnected before starting the wiring.
The following information is intended to be a guide for a proper installation. Comply with applicable local regulations for
electrical installations.
DANGER!
Les procédures recommandées dans cet avertissement visent à protéger l’utilisateur de la mort, de blessures graves et
de dégâts matériels importants.
Interrupteurs d’isolement de l’alimentation : Le matériel d’isolement de l’alimentation de l’onduleur et des alimentations
auxiliaires doit être prévu. Il doit couper les alimentations de l’onduleur (par ex.: pendant les tâches de maintenance de
l’installation).
Cet équipement ne doit pas être utilisé comme mécanisme d’arrêt d’urgence.
Vérifiez que l’alimentation est débranchée avant de commencer le câblage.
Les informations suivantes ont pour but de servir de guide pour une bonne installation. Respectez la réglementation
locale applicable sur les installations électriques.
10.1 MECHANICAL INSTALLATION
10.1.1 Environmental Conditions
The inverter installation location is an important factor to assure good performance and high product reliability. The inverter must be installed
in an environment free of:
Direct exposure to sunlight, rain, high humidity, or sea-air.
Inflammable or corrosive gases or liquids.
Excessive vibration, dust or metallic particles and oil mist.
