The grounding connection is also made through the power cable, which must be
inserted in a power socket (outlet) with protective ground contact. Therefore, the
power cable plug must always be inserted in a socket outlet provided with a
protective ground contact, and the protective action must not be negated by use
of an extension cord (power cable) without a protective conductor (grounding).
Whenever PL-1000RO units are installed in a rack, make sure that the rack is
properly grounded and connected to a reliable, low resistance grounding system.
2.1.2.1
Laser Safety Classification
PL-1000RO units equipped with laser devices comply with laser product
performance standards set by government agencies for Class 3B laser products.
According to IEC EN60825-2 standard, the following warning applies to Class 3B
laser products.
Figure 11: Class 3B Laser Warning
PL-1000RO units are shipped with protective covers installed on all the optical
connectors. Do not remove these covers until you are ready to connect optical
cables to the connectors. Keep the covers for reuse, to reinstall the cover over the
optical connector as soon as the optical cable is disconnected.
2.1.2.2
Laser Safety Statutory Warning and Operating Precautions
All personnel involved in equipment installation, operation, and maintenance
must be aware that the laser radiation is invisible. Therefore, the personnel must
strictly observe the applicable safety precautions and, in particular, must avoid
looking straight into optical connectors, either directly or using optical
instruments.
In addition to the general precautions described in this section, be sure to
observe the following warnings when operating a product equipped with a laser
device. Failure to observe these warnings could result in fire, bodily injury, and
damage to the equipment.
