Notes to Take before Installation
Before installing and using U9016B, the user should fully understand the warnings and notes
explained in this section and follow the instructions.
Do not disassemble the product
The user should not disassemble the product. If the user thinks that a repair is necessary,
contact the ubiQuoss Technical Support Team.
Installation site condition
The product should be installed in the site satisfying the following conditions to use the
product safely and stably:

Avoid the location whose temperature is too high or too low.

Avoid the top of a shaky shelf, a tilted location, or the place with big vibrations.

Avoid the location that is not ventilated or airtight.

Avoid the location with water or moisture and direct sunrays. Choose the cool and dry
location. If water gets into the product, it can cause an electric shock or the product
failure.

Keep the surroundings of the product clean and dust-free during or after the product
installation.

An electro-magnetic wave can cause a problem to the product operation, so avoid the
location where an electro-magnetic wave is generated.

Install the product in the location that the user can easily access and connect a cable to
the product easily.
Satisfying operational environment conditions
U9016B normally operates in the environment with the following conditions:

Operating temperature: 0 ~ 50
℃

Relative humidity: 10 ~ 85% (non-condensation)
Even in the environment that satisfies the above conditions, if the product operates in the
excessively low or high temperature for long time, the product life becomes shorter or the
product is vulnerable to damage. So always maintain a proper environment.
Prevent static electricity
Because static electricity can cause serious damage to the device or a circuit, the user and
the supervisor should take the following actions when using the product:

Always discharge the static electricity on the body before touching the product. (Use the
static electricity-preventing strap.)

Do not touch the internal components or connector pins with hands.

It is recommended to put the product into a static electricity-preventing envelop when
storing or moving the product.
Notes to take when using power

Ground all the cables connected to the product and connect them to the grounded
outlets to prevent and minimize the problem related to electro-magnetic wave or surge.
