required to correct the interference at his own expense.

This Class A digital apparatus complies with Canadian ICES-003.

Cet Appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.

The OI Displays contain software that incorporates many 

features that are designed to guide you safely through the 

commissioning process. Safety, however, is your responsibility.

Read all documentation carefully and respond appropriately to 

all error messages.

Improper user operation may result in PROPERTY 

LOSS, PHYSICAL INJURY or DEATH.

Using the OI Displays to change parameters, must be 

attempted by only experienced and/or licensed 

burner/boiler operators and mechanics.

NOTE: For S7999C OI Display installation instructions, see 

The OI Display can be mounted on the door panel of an 

electrical enclosure.

1. Select the location on the door panel to mount the dis-

play; note that the device will extend into the enclosure 

at least one inch past the mounting surface.

2. Provide an opening in the panel door 8-1/8 in. wide by 5-

7/8 in. high.

3. Place the OI Display in the opening and use it as a tem-

plate to mark the location of the four mounting screw 

holes. Remove the device.

4. Using pilot holes as guides, drill 1/4 in. holes through the 

door panel.

5. Place the display in the opening, aligning the mounting 

holes in the device with the drilled holes in the panel.

6. Secure the display to the panel with four #6-32 screws 

and nuts provided.

7. Select a location inside the enclosure for mounting the 

power supply.

8. Using the power supply as a template, mark the loca-

tions of the two mounting holes in the enclosure.

9. Remove the power supply.

10. Drill 1/4 in. holes through the panel at the marked loca-

tions and secure the power supply with the two #6-32 

screws and nuts provided.

11. Remove the 9-pin connector plug from the back of the OI 

Display.

12. Wire the connector to the power supply and the RS-485 

cables using the wiring diagram in Fig. 3.

13. Ensure the 9-pin connector plug is aligned with the 

header pins when inserting the 9-pin connector plug 

back onto the Display. Secure firmly.

The S7999B OI Display must be appropriately wired for both 

power and communications. An external 12V power supply 

(provided) with an appropriate power rating is connected to 

pins 1, 2 and 3 to power the device.

Communication is done over a RS-485 bus:

• COM1 connected directly to the SOLA Device J3 connector 

to either Modbus (MB1 or MB2).

• COM2: A bus to the Building Automation System.

See Fig. 2 for S7999B Display connector terminals. Wiring 

connections are listed in Table 1. See Fig. 3 for wiring.
