accessible from the cover plate as illustrated in Figure 3-1. Figure 3-6 in this manual provides the wiring terminations for connections to the Sentry controller. When the module is operated in conjunction with a Sentry controller, the alarms outputs in the module can both be set to “Sentry”, allowing the Sentry controller to manage alarm acknowledge and reset rather than the sensor module. The alarm relay outputs are triggered by the alarm values established in the module, and can be

2. CAUTIONS & WARNINGS 2.1 INTRODUCTION Although IT Transmitter Modules are designed and constructed for installation and operation in industrial applications including "hostile" environments, caution should be taken to insure that the installation is made in compliance with this instruction manual and that certain procedures and conditions are avoided. This chapter discusses the necessary cautions. Read the entire chapter prior to installation of the equipment. 2.2 IT MODULES - GENERAL

3. INSTALLATION NOTE All IT modules are factory are pre-configured and calibrated. All modules are tagged to indicate the configuration including the sensor module number. Identify all components during unpacking and install using the factory configuration. 3.1 SENSOR MODULE LOCATIONS Select locations for each sensor modules based on the following: • Modules should be placed close to the potential source of gas. • Modules should be placed in areas accessible for calibration. • Sensors

NOTES The drain wire of shielded cable must NOT be used as one of the conductors. Installation and wiring must be in accordance with the National Electrical Code. Temperature o rating of cable wire must be at least 75 C. If cable runs through higher temperature environments, it must be specified for that environment. 3.3 ENCLOSURE INSTALLATION To protect the transmitter and sensor assembly they should be removed from the enclosure and preserved until final installation and wiring te
