further details. Wall mounting holes are located in each corner of the enclosure (see 

Disconnect power to the loop and install the meter as illustrated in 

 on page 6 and 

page 9. Replace the enclosure cover.

The display PCB and input signal PCB are connected together with one black and one red 
wire. The wires are soldered to the display PCB and connected to a screw terminal 
connector on the input signal PCB. 

1.

Remove enclosure cover and the display PCB as described in steps 1 to 3 of 

2.

Install loop jumper over both pins to bypass display PCB and allow the signal to flow 

through the loop jumper. The display turns off when jumper is installed.

3.

Disconnect the black and red signal wires from the screw terminal connector.

4.

Loosen completely the right-side screw and lift display PCB from enclosure.

5.

Restore enclosure cover to the base to prevent contamination of components.

1.

Loosen the four screws on the enclosure cover and remove the cover.

2.

Secure display PCB to enclosure using right-side screw; do not tighten screw to 

allow rotation of display PCB while accessing input signal PCB.

3.

Connect red wire to S+ terminal and black wire to S- terminal, as shown in 

4.

Remove loop jumper to allow the signal to flow through display PCB (save push-on 

jumper by placing over one pin only).

5.

Tighten screws holding display PCB and install enclosure cover.

Two modes of input signal allow the user to remove the display PCB for service without 
interrupting the loop as indicated above and operate the display PCB at another location 
in a non-hazardous area. The loop remains connected to the input signal PCB while the 
display PCB is absent for service. The user may operate the display PCB at another 
location by connecting a signal to “S+” and “S-” wires on the display PCB. Refer to
