Electrical safety
Observe the following safety instructions during installation and service activities.
DANGER
v
An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the devices that attach to the
system. It is the responsibility of the customer to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock.
v Before installing or removing signal cables, ensure that the power cables
for the system unit and all attached devices are unplugged.
v
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from
the existing system before you add a device.
v
Use one hand, when possible, to connect or disconnect signal cables to
prevent a possible shock from touching two surfaces with different
electrical potentials.
v During an electrical storm, do not connect cables for display stations,
printers, telephones, or station protectors for communications lines.
v
To prevent electrical shock hazard, disconnect all power cables from the
electrical outlet before relocating the system.
CAUTION:
v
This product is equipped with a three-wire power cable and plug for the
user's safety. Use this power cable with a properly grounded electrical outlet
to avoid electrical shock.
v
The DR550 DR2 is configured with two mainline power cords.
Laser safety
This equipment contains Class 1 laser products, and complies with FDA radiation
Performance Standards, 21 CFR Subchapter J and the international laser safety
standard IEC 60825-1.
CAUTION:
Data processing environments can contain equipment transmitting on system
links with laser modules that operate at greater than Class 1 power levels. For
this reason, never look into the end of an optical fiber cable or open receptacle.
