UM344-2 INSTALLATION

September 1995

4.5 ELECTRICAL INSTALLATION

This section describes loop wiring for Point-To-Point and Multi-Drop Networks. Refer also to Section 4.6

for installations in hazardous locations. Figure 4-12 shows signal and sensor termination terminal strips in

the Transmitter’s enclosure.

The following should already have been completed:

Ÿ Selection of either analog or digital operating mode and corresponding Point-To-Point or Multi-Drop

Network; Section 4.3.3.

Ÿ Selection of a power supply; Section 4.3.4.

Ÿ Mechanical installation of Transmitter(s) installed; Section 4.4.

Ÿ Pulling of loop and sensor cables through conduit and into terminal compartment; Section 4.4.5.

Connect the transmitter to the loop as follows.

1. Access transmitter signal terminals by unscrewing the short enclosure cap.

2. As shown in Figure 4-12, there are two terminal strips:

Upper Terminal Strip

• SIGNAL (+) and SIGNAL (-): Transmitter Network Connections

• TEST (+) and TEST (-): Analog test (milliammeter) connections

Lower Terminal Strip

• #1: RTD (+) or OHM (+); TC (+) or mV (+) sensor connections

• #2: RTDI sensor connection

• #3: RTD (-) or OHM (-); TC (-) or mV (-) sensor connections

3. Determine method of connection to transmitter signal (loop) terminals.

Strip loop cable and conductors. Install ring tongue or spring spade terminals for #6 screws and the

cable conductor gauge. If terminals will not be used, tin conductor ends and form a loop.
