INSTALLATION

4. Installation
This chapter outlines the most important aspects of the installation and summarizes the site considerations that the installer
must take into account when choosing a location for the unit. Reference to DigiVu infers both DigiVu and DigiVu Mini unless
specifically stated.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU
unless the model is specifically stated. Reference to DVIS is synonymous with DigiVu as these
products run on the same firmware.

4.2 Recommended Installation Environment
Carefully unpack the equipment from the shipping box. If the box or equipment is damaged, notify the freight company to make
a damage claim. If you suspect that there is a problem with the equipment that may compromise safe operation, do not install
or operate it.
NOTE: This equipment is intended for installation in a RESTRICTED ACCESS LOCATION only.
Not for use in a computer room as defined in the Standard for Protection of Electronic Computer/
Data Processing Equipment, ANSI/NFPA 75. This equipment is intended for use in a fixed position
and should be installed securely before operation is undertaken.
4.3 Equipment Safety Grounding
It is imperative that the chassis be connected to a permanent building ground in a manner
that will ensure that the exposed metal parts are constantly connected to ground even
when the power cord may be disconnected temporarily. A grounding lug is provided on the
front panel to conveniently effect such a connection. The following guidelines are provided
to clarify the requirements for the installation to meet UL, CUL and CB standards. The use
of the words "Ground" and "Earth" as well as "Grounding" and "Earthing" may be used
interchangeably and in this context, have the same meaning.
4.3.1 Connection to Earth
The supplementary equipment grounding conductor is to be installed between the back
panel ground connector and earth, that is, in addition to the equipment ground conductor
in the power supply cord.
4.3.2 Conductor Size
The supplementary equipment grounding conductor may not be smaller in size than the branch-circuit supply conductors
or a minimum #14 AWG. The supplementary equipment grounding conductor is to be connected at the back panel terminal
provided, and connected to earth in a manner that will retain the earth connection when the power supply cord is unplugged.
The connection to earth of the supplementary grounding conductor shall be in compliance with the appropriate rules for
terminating bonding jumpers in Part V of Article 250 of the National Electrical Code, ANSI/NFPA 70, and Section 10 of Part I
of the Canadian Electrical Code, Part I, CSA C22.1.
