INITIAL
Energizing a medium voltage controller or line-
up of controllers for the first time is potentially
dangerous. Therefore only qualified personnel
as defined in the SAFETY section of this
manual, should energize the equipment
(Fig. 49). If faults caused by damage or poor
installation practices have not been detected in
the PRE-ENERGIZATION CHECK section, major
damage including personal injury can result
when the power is applied. Extra precaution is
recommended on initial energization of the
equipment.
Hazardous Voltage.
Improperly installed, or
damaged equipment will

energizing
this
equipment.
Only qualified personnel
should energize this
equipment.
In order to minimize the risk of injury or
damage, there should be no load on the

downstream loads, including those such as
distribution equipment and other remote
devices, should be turned off. The isolation
