2-2 INTELLIGENT FIELD TRANSMITTER (IFT) INSTALLATION

a.Mechanical Installation

The outline drawing of the IFT module in Figure 2-4 shows mounting centers and clearances. The NEMA 4X enclosure is de- signed to be mounted on a wall or bulk- head. The IFT should be installed no more than 1200 feet (364 m) from the optional HPS or 150 feet (45 m) from the probe if HPS is not installed in the system.

To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation of this equipment, con- nection to the main electrical power supply must be made through a circuit breaker (min 10A) which will discon- nect all current carrying conductors during a fault situation. This circuit breaker should also include a me- chanically operated isolating switch. If not, then another external means of disconnecting the supply from the equipment should be located close by. Circuit breakers or switches must comply with a recognized standard such as IEC 947.

NOTE

Refer to Figure 2-6 for fuse locations and specifications.

1.The IFT can be configured for 100, 120, 220, or 240 line voltages. For 120 Vac usage, install JM8, JM7, and JM1 on the power supply board. For 220 Vac usage, install jumpers JM6, JM5, JM2 (refer to Figure 2-5 and Figure 2-6).

2.For installations where the cable run is less than 150 feet (45 m), the IFT can

be configured to connect directly to a probe. An optional HPS is available for cable runs over 150 feet (45 m). The electrical connections for a non-HPS equipped system should be made as de- scribed in the electrical installation dia- gram, Figure 2-7. Refer to Figure 2-13 for connections for an HPS equipped system.
