For complete testing it will be necessary to apply a short to the system.
DANGER
Hazard of Electrical Shock, Burn or Explosion
Qualified personnel must perform testing referred to in this manual. All power
should be disconnected prior to making any connections or disconnection. All
exposed metallic enclosures must be grounded.
Failure to observe these precautions may result in death or severe
personal injury.
!
This should be done at a convenient downstream location (and not at the main substation for example) using a
suitable low impedance protected by a HRC fuse mounted in a grounded enclosure for safety. This test should
only be performed when there is no other fault indicated on the system.
Cleaning:
To clean the
Gemini
, first disconnect the electrical power. Using compressed air, blow away any accumulated
dust and foreign material. The exterior may be cleaned using a slightly damp cloth. Ensure that the
Gemini
is
completely dry before energizing. Close the front door and reconnect electrical power. Test the unit again before
returning to normal service.
