Introduction

This document is an Operation Manual containing diagrams and step-by-step instruction for proper operation of the Otis Instruments, Inc. GenII OI-7032. This document should be read before initial operation of the product.
Should a question arise during the use of the product, this document will serve as a first reference for consultation. If further questions arise, or if the device is not working properly, please contact the sales representative of this product.

Warnings

• The OI-7032 should only be used in an environment that constantly remains between the range of
-20 to 122 degrees Fahrenheit. If the OI-7032 is at risk of being exposed to temperatures that are outside the previously stated range, DO NOT install the device in that location. For applications in areas with the potential of reaching extreme temperatures, Otis Instruments recommends using the OI-7032 indoors only (in a temperature-controlled environment).
• Even when the Power switch is in the off position, the AC and DC terminals are still hot—
regardless of if the device is wired as DC.
• Wiring Configuration Warnings:
● Provide a clean and stable 24 Volts DC (nominal; 22-26 Volts DC) voltage. Failure to to do
so may cause the unit (and any wired sensors that are connected to the unit) to not operate properly.
● Voltage spikes higher than 26 Volts may damage the unit.
● Solar Panel power (with battery backup): This options may be used to power the unit,
however, care must be taken to ensure the proper voltage and wattage is used.
NOTE: The size that the solar panel should be (10, 30, 50, or 100 watts, for example) depends on several factors, including: geographical area, line-of-sight access to the sun, number of wired sensors connected, and weather conditions.
Please consult a solar panel manufacturer for specific details. Otis Instruments, Inc. may also be contacted to provide guidance and recommendations.

Wiring Configurations

The following Wiring Configurations must be completed before initial operation of the product.

DC Power-in (24 Volts DC (nominal; 22-26 Volts DC))

NOTE: The unit will be wired for the power-type that is requested by the purchaser when shipped from Otis Instruments, Inc.
When wiring the device, the following should be considered:
● Provide a clean and stable 24 Volts DC (nominal; 22-26 Volts DC) voltage. Failure to to do
so may cause the unit (and any wired sensors that are connected to the unit) to not operate properly.
● Voltage spikes higher than 26 Volts may damage the unit.
● Solar Panel power (with battery backup): This options may be used to power the unit,
however, care must be taken to ensure the proper voltage and wattage is used.
NOTE: The size that the solar panel should be (10, 30, 50, or 100 watts, for example) depends on several factors, including: geographical area, line-of-sight access to the sun, number of wired sensors connected, and weather conditions.
