Installation Instructions
Description
The nVent RAYCHEM NGC-UIT-ORD and nVent RAYCHEM
NGC-UIT-OUT are panel mounted displays used in conjunction with
other approved nVent RAYCHEM control and monitoring devices.
The NGC-UIT-ORD is rated IP 54 (NEMA 12), however, the display can
best be viewed indoors or when protected from direct sunlight.
The NGC-UIT-OUT is rated IP 56 (NEMA 4X) and the display can be
viewed outdoors or indoors. The NGC-UIT kits include all hardware
required for mounting in a suitable electrical panel. These
instructions describe how to mount the NGC-UIT in an electrical
panel and are intended only for personnel experienced in panel
construction.
Tools Required
• Masking tape • #16 (3/16) drill bit
• 11/32 inch nut driver • Jig saw (recommend using
• Metal file carbon steel blade with 24 TPI)
