requests or doubts that could arise, it is recommended to keep
the CD-ROM documentation in a safe place with easy access.
The following terms are used in the document indistinctly to
be referred to:
•«EMi3, equipment, stabilizer, voltage stabilizer or
unit».- Servomotor voltage equipment stabilizer.
•«T.S.S.».- Technical Service and Support.
•«client, fitter, operator or end-user».- are used indis-
tinctly and by extension, to be referred to the fitter and/or
operator which will make the corresponding actions, being
responsible the same person about the actions to take on
behalf of himself.
•In case of installations with IT neutral regime, the switches,
circuit breakers must break the NEUTRAL a part from the
three lines.

4.1.1. Equipment views.
Tables from 1 to 8 show the standardised models with their
physical dimensions and weights, as well as the correlation
with the illustrations of Fig. 1 to 11.
All models have a control panel with LCD as an interface be-
tween the equipment and the end-user, which gives information
of different nature through its menus structured in categories
(see section 7).
Three phase equipments consisting of three single phase cabi-
nets, each one of them will have their own control panel.
Any figure referred to the main specifications of the
equipment can be checked in the nameplate of the
equipment. Act for your installation accordingly.

(0) Models identified in tables 1, 3, 5 and 7 with this annotation (0), do not include
the slot for SICRES (SL) and the RS232 connector (X33) as standard.
(1) The term «D. x W. x H.» corresponds to the maximum dimensions in mm of «Depth
x Width x Height» and it includes those parts assembled as standard in each model
that exceeds from the frame of the case or cabinet and they are essential for its
operation or safety, like: switches, terminal cover, base (foot or stand), casters, ...
(2) The lifting lugs are not contemplated in the total height of the equipment in the
models corresponding to Fig. 1, 2 and 3. The lifting lug height is 45 mm, add it
to the height stated in each model to get the total height.
The dimensions stated in tables 1 to 8 corresponds to standard
equipments.
When an equipment includes the manual Bypass option,
depending on the model (power and ranges), the physical
dimensions can change as regards to the standard model, nev-
ertheless and due to its easy connection, it will not mean any
obstacle to do the needed tasks because the labelling in the
equipment will identify those parts conveniently.
