CAUTION! This UPS series is ONLY intended to be installed in an indoor
temperature controlled environment that is free of conductive contaminants.
This UPS series is not intended for use in a computer room as defined in the
Standard for the Protection of Electronic Computer/Data Processing Equipment ANSI/NFP A 75.
CAUTION! Connect the UPS to a two pole, three wire, grounded, utility
power AC wall outlet. The receptacle must be connected to the appropriate
branch protection (circuit breaker or fuse). Connection to any other type of
receptacle may result in a shock hazard and violate local electrical codes. Do
not use extension cords, adapter plugs, or surge strips.
CAUTION! To reduce the risk of fire, connect only to a utility power circuit
provided with 20 amperes maximum branch circuit over-current protection in
accordance with the National Electric Code, ANSI/NFPA 70.
CAUTION! T o reduce the risk of electrical shock with the inst allation of this
UPS equipment and the connected equipment, the user must ensure that the
combined sum of the AC leakage current does not exceed 3.5mA.
Veuillez lire ce manuel avant l'installation de l'onduleur modèles EN350, EN550.
Il contient de l'information importante qui doit être respectée au cours de
l'installation et de l'entretien de l'onduleur et des batteries. Cette information
vous permettra de correctement installer le système pour atteindre son
rendement maximum en toute sécurité.
CAUTION! The maximum ambient operating temperature for this UPS series
is 40°C (“0 ~ 40°C” for Ambient Operation).
The external vents and openings on the UPS are provided for ventilation.
T o ensure reliable operation of the UPS and to protect the UPS from overheating, these vents and openings must not be blocked or covered. Do not
insert any object into any of the vents or openings that may hinder the ventilation.
Install the UPS system in a well ventilated area, away from excess moistu-
re, heat, dust, flammable gas or explosives.
Leave adequate space (at least 20cm) around all sides of the UPS system
