1.3 PRELIMINARY RECOMMENDATIONS
The following are some preliminary recommendations, which should be read before starting
the product installation and operation procedures.
DANGER!
Failure to comply with the safety instructions may result in risk of death and/or
damage to the equipment. The product has its own power source (batteries).
Therefore, the output connections and/or terminals may be energized even if the
input power is not available or connected to the equipment. This equipment has
potentially hazardous voltages.
DANGER!
Do not block or insert objects into the ventilation fins. Never cover the equipment
with other materials or objects, as it may cause overheating and risk of fire. All
repairs and maintenance jobs must be performed with the equipment completely
de-energized and only by technicians of the WEG Authorized Technical Assistants.
DANGER!
Always disconnect all power sources (main and battery) before touching any
electrical parts connected to the equipment.
Many components may remain charged with high voltages and/or moving (fans)
even after the battery has been disconnected.
Wait for at least 10 minutes to ensure the full discharge of the capacitors.
DANGER!
Batteries must be recycled. Never dispose of batteries by means of incinerators,
crushers, trash compactors, ordinary trash cans or by throwing them directly
into the environment. There are risks of explosion or fire when they are exposed
to flame, subjected to pressure or come into contact with energy-carrying
materials (metals or liquids), in addition to contaminating the environment due to
the materials part of their composition.
DANGER!
When in operation, electric energy systems, such as transformers, converters,
motors and cables, generate electromagnetic fields (EMF). Therefore, there is
risk for people with pacemakers or implants who stay near those systems. Thus,
such people must stay at least 2 meters away from this kind of equipment.
ATTENTION!
In order to reduce the risk of fire and electric shock, install the product indoors in
an environment with controlled humidity and temperature, free of pollutants and
explosive agents, not exposed to direct sunlight. Do not install the product in a
place where the temperature and humidity are out of the technical specifications
indicated in Chapter 7 TECHNICAL DATA on page 7-1.

Safety Instructions
RTDW | 1-3
ATTENTION!
The performance and safety of the system are directly related to the correct sizing
and execution of the electrical design, which must comply with ABNT standards,
especially NBR 5410 (Low Voltage Electrical Installations).
ATTENTION!
Before installing the product, make sure that the available infrastructure is suitable
and complies with the product technical specifications. (input supply voltage,
output, battery and load).
ATTENTION!
Electronic boards have electrostatic discharges sensitive components. Do not
touch the components or connectors directly. If necessary, first touch a grounded
metallic frame or wear a suitable grounding strap.
ATTENTION!
The operation and installation of this equipment requires detailed instructions
provided in the User Manual and and Electrical Design. The manuals are available
for download on the website: www.weg.net.
NOTE!
In case of battery replacement, the package of the new batteries can be used
to store the old ones or put them in individual plastic bags and deliver them
directly to your supplier. In case the supplier does accept them, contact the
battery manufacturer or distributor, as they are responsible for the collection. The
batteries replaced by WEG Authorized Service Centers are collected by WEG
and sent to the respective suppliers for proper recycling.
NOTE!
Read this manual thoroughly before installing or operating this equipment. After
reading this document, keep it in an easily accessible place for the other users
of the product.
