3. Ventilation - Any openings in the unit enclosure are provided for ventilation to prevent
overheating and ensure reliable operation. Do not block or cover these openings. Do not
place the unit in an enclosure unless proper ventilation is provided, or the manufacturer's
instructions have been adhered to.
4. Object and liquid entry - Never push objects of any kind into this unit through openings
as they may touch dangerous voltage points or short-out parts that could result in a fire
or electrical shock. Never spill liquid of any kind on the unit. Do not place objects filled
with liquids, such as vases or cups, on the unit.
5. Lightning - For added protection during a lightning storm, or when leaving this unit
unattended and unused for long periods, unplug the unit from the wall outlet and
disconnect the cable system. This will prevent damage to the unit from lightning and
power line surges.
6. Controls adjustment - Adjust only those controls specified in the operating instructions.
Improper adjustment of other controls may cause damage to the unit. Use of controls or
adjustments, or performance of procedures other than those specified, may result in
hazardous radiation exposure.
7. Overloading - Do not overload outlets and extension cords. This can cause fire or
electrical shock.
8. Power cord and plug protection - Protect the plug and power cord from foot traffic,
being pinched by items placed upon or against them at electrical outlets, and its exit from
the unit. For units intended to operate with 230 VAC, 50 Hz, the input and output power
cord must comply with the latest versions of IEC Publication 227 or IEC Publication 245.
9. Power disconnect - Units have power supplied to the unit whenever the power cord is
inserted into the power source, or when High Power-over-Ethernet (High PoE) power is
provided over the Ethernet CAT 5E/6 cable. The unit is operational only when the ON/OFF
switch is in the ON position. The power cord is the main power disconnect device for
switching off the voltage for all units. When High PoE or PoE+ (820.3at) is used to power
the unit, the power is provided over the Ethernet cable, which is then the main power
disconnect device for switching off the voltage for all units.
10. Power sources - Operate the unit only from the type of power source indicated on the
label. Before proceeding, be sure to disconnect the power from the cable to be installed
into the unit.
For battery powered units, refer to the operating instructions.
For external power supplied units, use only the recommended or approved power
supplies.
For limited power source units, this power source must comply with EN60950.
Substitutions may damage the unit or cause fire or shock.
For 24 VAC units, voltage applied to the unit's power input should not exceed ±10%, or
28 VAC. User-supplied wiring must comply with local electrical codes (Class 2 power
levels). Do not ground the supply at the terminals or at the unit's power supply terminals.
If unsure of the type of power supply to use, contact your dealer or local power company.
11. Servicing - Do not attempt to service this unit yourself. Opening or removing covers may
expose you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
12. Damage requiring service - Unplug the unit from the main AC power source and refer
servicing to qualified service personnel when any damage to the equipment has occurred,
such as:
the power supply cord or plug is damaged;
exposure to moisture, water, and/or inclement weather (rain, snow, etc.);
liquid has been spilled in or on the equipment;
