Operating Environment & Safety Warnings
Situate and operate the TerraMiner in a cool, dry environment, away from radiators or other heat
sources. Extremes in temperature will affect the TerraMiner’s performance and may cause irreparable
damage to the unit. The TerraMiner should not be used near water or excessive moisture. The
TerraMiner is designed to operate at a room temperature between 5° C and 35° C (41° F-95° F) and up to
4000 ft. above sea level.
Leave enough clearance at both the front and rear of the TerraMiner to allow proper ventilation and
ensure that all fan grills are unobstructed.
To help maintain proper system operation, check regularly that all fan grills are free from potential
blockages (such as dust or pet hair) that may affect the unit’s cooling efficiency. Any restrictions to
airflow can result in damage to the TerraMiner. The TerraMiner should be turned off and both power
cables disconnected from the power supplies before cleaning. Use a cloth to clear the vents at the front
and back of the TerraMiner of any dust or material that has collected there.
Do not insert objects, fingers or other body parts into any fan grill or vent in the TerraMiner, this can be
hazardous and may result in an electrical shock and/or fire and may damage the unit.
To protect the TerraMiner from damage in case of changes in the electrical power supply, the use of a
surge protector or uninterruptible power supply (UPS) rated for at least 15 amps per TerraMiner power
supply (i.e. 2 x 15 amps or 1 x 30 amps) is recommended. The socket outlet shall be installed near the
equipment and shall be easily accessible.
In the event of an electrical storm the TerraMiner should be disconnected to protect it from damage.
The TerraMiner is designed to operate in a horizontal position, either on a desk or rack-mounted.
Operation in any other position is not recommended. Never rest the TerraMiner on its back plane facing
upwards as this may damage the rear of the unit.
The TerraMiner is a self-contained device with no user-serviceable parts inside. Opening the
TerraMiner’s case will void the product warranty.
