Chapter 6. Removal and Replacement Procedures
Before performing any of the removal or replacement procedures in this chapter,
read the following notice.
DANGER
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.
Before installing or removing signal cables, ensure that the power
cables for the system unit and all attached devices are unplugged.
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.
Use one hand, when possible, to connect or disconnect signal cables
to prevent a possible shock from touching two surfaces with different
electrical potentials.
During an electrical storm, do not connect cables for display stations ,
printers, telephones, or station protectors for communications lines.
CAUTION:
This product is equipped with a 3-wire power cable and plug for the user's
safety. Use this power cable in conjunction with a properly grounded electrical
outlet to avoid electrical shock.
