WARNING
These instructions do not replace the need for
utility operation standards . Any conflict between the
information in this document and utility practices
should be reviewed by the appropriate utility personnel
and a decision made as to the correct procedures to
follow .
A GridMaster Microgrid Control System is connected
to equipment that may be operating at primary
voltage levels . High voltage may be present in the
wiring to the equipment’s intelligent controls or to
the equipment itself during certain failures of the
equipment’s wiring or grounding system, or due to a
failure of the equipment itself . For this reason, access
to the GridMaster controller should be treated with the
same safety precautions that would be applied when
accessing other high-voltage lines and equipment .
Follow all locally approved safety procedures when
working on or around the controller .
Before attempting to access an existing equipment
installation, check carefully for visible or audible signs
of electrical or physical malfunction . Do this before
touching or operating the GridMaster controller or
any other part of the installation . These warning
signs include such things as smoke, fire, open fuses,
crackling noises, loud buzzing, etc . If a malfunction
is suspected, treat all components of the installation,
including the GridMaster controller and associated
mounting hardware, as though they were elevated to
primary (high) voltage .
Whenever accessing or performing maintenance
on the GridMaster controller, follow your company’s
operating procedures to disable automatic operation
of the equipment to prevent unexpected operation of
the equipment .
Familiarize yourself with the parts of a GridMaster
controller. See Figure 1.
