Protection against Electrostatic Discharge
An electrostatic discharge (ESD) occurs between two objects when an object
carrying static electrical charges touches or is brought near the other object.
Static electrical charges appear as a result of friction between surfaces of
insulating materials or separation of two such surfaces. They may also be induced
by electrical fields.
Routine activities, such as walking across an insulating floor, friction between
garment parts, and friction between objects, can easily build charges up to levels
that may cause damage, especially when humidity is low.
C
AUTION
:
PL-1000RO internal boards contain components sensitive to ESD.
To prevent ESD damage, do not touch internal components or connectors. If you
are not using a wrist strap, before touching a PL-1000RO unit or performing any
internal settings on the PL-1000RO, it is recommended to discharge the
electrostatic charge of your body by touching the frame of a grounded equipment
unit.
Whenever feasible during installation, use standard ESD protection wrist straps
to discharge electrostatic charges. It is also recommended to use garments and
packaging made of anti-static materials, or materials that have high resistance,
yet are not insulators.
2.2
Site Requirements
This section describes the PL-1000RO site requirements.
2.2.1
Physical Requirements
The PL-1000RO units are intended for installation in 19-inch or 23-inch racks or
placed on desktops or shelves.
All the connections are made to the front panel.
2.2.2
Power Requirements
AC-powered PL-1000RO units should be installed within 1.5m (5 feet) of an easily
accessible, grounded AC outlet capable of furnishing the required AC supply
voltage, of 100 to 240 VAC, 50/60 Hz, and 1.5A maximum.
DC-powered PL-1000RO units require a -48 VDC, 3A maximum DC power source
with the positive terminal grounded. In addition, the DC power connector
contains the chassis (frame) ground terminal (see
)).
2.2.3
Ambient Requirements
The recommended ambient operating temperature of the PL-1000RO is 0° to
+45°C/+32° to +113°F, at a relative humidity of 5% to 85%, non-condensing.
