Chapter 9. Removal and Replacement Procedures

Servicing of this system can be performed with the system either in the vertical or
horizontal position.
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 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.
