4. Equipment installation
4.1 General
This section contains complete instructions
for installing AKD-20 and Entellisys low
voltage switchgear.
Caution: Personnel installing this equipment must
be thoroughly familiar with this instruction manual
and all articles of the National Electrical Code
applicable to the installation of this switchgear. In
addition, all drawings, both mechanical installation
and electrical, must be understood and strictly
followed to prevent damage to the switchgear or
equipment being protected by the switchgear.
Prudence: Le personnel installant cet équipement
doit parfaitement connaître ce manuel
d'instructions, ainsi que tous les articles du Code
national électrique des États-Unis applicables à
l'installation de cet appareillage électrique.
En outre, ce personnel doit bien comprendre
et suivre à la lettre tous les dessins, mécaniques
et électriques, afin d'éviter d'endommager
l'appareillage ou l'équipement protégé par
l'appareillage.
Note: Before installation work is started, it is
important to review all of the drawings provided,
including the equipment arrangement drawings,
site installation drawings, elementary and remote
connection drawings, mechanical connection
drawings, and the summary of equipment list.
Remarque: Avant de commencer la procédure
d'installation, il est important de passer en revue
tous les dessins fournis, notamment les dessins
d'organisation de l'équipement, les dessins pour
l'installation sur site, les dessins des connexions
élémentaires et distantes, les dessins des
connexions mécaniques, ainsi que le récapitulatif
de la liste des équipements.
All expendable hardware for shipping purposes
only, is painted yellow or tagged with yellow
adhesive tape and may be discarded at completion
of the installation phase.
Site location
In general, the location of the switchgear
equipment will have been predetermined
during the specification and/or procurement
of equipment phases. Indoor locations within
buildings impose certain requirements which
must be met so that the switchgear may operate
efficiently with a minimum of maintenance.
In locating the switchgear, adequate aisle space
must be provided at the front and rear of the
equipment to ensure proper ventilation of the
equipment and to allow service and maintenance of
the equipment with the front and rear doors open.
The recommended aisle space is shown on the floor
plan supplied with the equipment drawings.
The switchgear equipment should be placed in an
area where clean, dry air is free to circulate around
and above it. Since air is taken into the equipment
at the bottom of each section and exhausted at the
top, a location with good airflow must be provided
for efficient operation. A minimum of 30 inches of
clear space above the equipment is recommended.
