Page 3: Section I - Overview
SECTION I – OVERVIEW 1.1 INTRODUCTION The nVent RAYCHEM NGC-30 is a fully wired and tested control and monitoring system used with electric heat tracing. This manual provides information pertaining to the installation, operation, testing, adjustment, and maintenance of all components of the RAYCHEM NGC-30 System. -
Page 4: Section2 - Installation And Wiring
Procedures for installing the RAYCHEM NGC-30 are given in this section. If the shipment is incomplete, mechanically damaged, defective in any way, or does not pass the electrical performance tests, notify the nearest nVent representative. -

Fig. 2.4 Typical RTD installation 2.6.5 CONNECTING THE RS-485 DEVICE NETWORK The NGC-UIT2 display is typically linked to a network of RAYCHEM NGC-30-CRMs/-CRMSs and optional nVent RAYCHEM RMM2s and PLIs. These are connected to the RAYCHEM NGC-UIT2 using an RS-485 communication cable (shielded, two conductor, twisted pair). The following illustration shows how the RS-485 network for the NGC-UIT2 system may be configured. - Page 8 NGC-30-CRM/-CRMS board in the RAYCHEM NGC-30 panel. To make this connection, a pre-wired terminal block has been provided in the RAYCHEM NGC-30 panel. Connect the RS-485 wire from the RMM2 to TB (per the panel drawing) while maintaining the correct polarity.
