Installation Requirements
Before setting up an OT-2, make sure that your installation site meets the requirements described in this section. And, follow all of the safety guidance here and throughout the installation instructions.
Placement¶
-
Weight bearing: The OT-2 weighs 42 kg (93 lbs). Place the robot on a surface that can support its weight plus the weight of any modules, labware, liquids, or other lab equipment that may be used in your work.
-
Bench surface: A good workspace is stationary, sturdy, level, and liquid-resistant. Tables or benches with wheels (even locking wheels) are not recommended. OT-2 gantry movements can shake light weight or moveable tables.
-
Operating space: The OT-2 needs a working area with minimum height, depth, and width of 66 cm x 57 cm x 63 cm (≈26" x 23" x 25").

Also, leave extra side and back clearance for cables, USB connections, and to help dissipate exhaust from modules that heat and cool.
Power consumption¶
The OT-2 has the following power requirements:
- Mains power: 100–240 VAC, 50/60 Hz
- Input power supply: 36 VDC, 10 A
The total power consumption of the OT-2 varies depending on the requirements of your protocol.
- Operating: ~ 100–180 W
- Idle: ~ 90–120 W
Environmental conditions¶
Opentrons has validated the performance of the OT-2 in conditions recommended for system operation as follows:
- The robot is designed for indoor use only.
- Temperature range: 20 °C ± 4° C (68 °F ± 7.2 °F).
- Relative humidity: 40-60% (up to 80% is acceptable, but outside the recommended range).
- Altitude: Up to 2,000 meters above sea level.
The OT-2 is safe to use in conditions outside of the recommended specifications, but your results may vary.
