4.1. Installation Process

4.1.1. Panel Mounting for New Installations

This section describes the following:
1. Selecting the EPM 2000 location
DANGER
All Installation, wiring and periodic maintenance of the EPM 2000 as well as
its associated circuits involves high voltages and currents. While this
manual suggests several safety and reliability steps, it must be used in
conjunction with the safety codes in force at your location. Failure to
practice safe working procedures is likely to cause damage to the
installation, severe injury and / or death. All work including handling of
electrical circuits during Installation, wiring and periodic maintenance,
must be done only by qualified personnel.
Neither GE nor its agents may be held responsible for damage or death
arising out of the wiring and / or PT, CT or other external circuits.
The covers of the EPM 2000 should never be dismantled or opened. There
are no user-serviceable parts inside. The EPM 2000 contains high-precision
components which require special handling available only at authorized GE
service locations. High voltages are likely to be present inside even after
the EPM 2000 has been switched off. Opening the covers of the EPM 2000
and/or any attempts to dismantle, service, repair or modify the unit by
unauthorized persons may cause severe injury, will damage the unit and
will also render GE's warranty void.
2. Location and Mounting considerations.

4.1.2. Location

4.1.2.1. Usage

First, decide on how the EPM 2000 is going to be used. If you do not already have an Energy
Management program in operation, then your Energy Consultant should be able to help you
identify which load(s) offer maximum savings potential. This will help you decide: Which
point is to be monitored, where the readings will be viewed from, who must have access to
the instrument and how often. For best performance, choose a location which provides all the
required signals with minimum wiring lengths.

4.1.2.2. Panel Considerations and Environment

The EPM 2000 is a high - precision measuring instrument and its operating environment is of
utmost importance. For maximum performance, the instrument should be mounted in a dry,
dust-free location, away from the heat sources and strong electromagnetic fields. To operate
reliably, the following conditions must be met:
The EPM 2000 should be separated from other equipment and sufficient space must be
provided all around for cooling air to rise vertically past the instrument. The cooling air
temperature must be below the specified operating temperature.
