DESCRIPTION
These instructions will guide the installer on how to convert
from nVent RAYCHEM NGC-UIT-OUT to
nVent RAYCHEM NGC-UIT2-HAZ and are intended only for
personnel experienced in panel construction.
TOOLS REQUIRED
• Masking tape
• #7 (.201) drill bit
• 11/32 in. Nut Driver
• 3/8 in. drill bit
• Metal file
• In-line torque wrench with 3/8 socket
• Zipcut Disc for cutting Stainless Steel panels
(5.0 in x 0.45 in x 7/8 in)
Note: the Zipcut disc is used to cut the opening in the door for the
NGC-UIT2-HAZ display. Other cutting type tools can be used.
The NGC-UIT2-HAZ is an electronic unit.
During installation, take the following
precautions to avoid damage to its
electronic components.
• Handle with care to avoid mechanical
damage.
• Keep electronics dry.
• Avoid exposure to static electricity.
• Avoid contamination with metal filings,
liquids, or other foreign matter.
• Take care to protect the user interface
board on the enclosure door.
• Use agency-approved conduit bushings,
adapters, and cable glands to keep the
enclosure protected from dust and fluids.
