Danger notices
A danger notice calls attention to a situation that is potentially lethal or extremely
hazardous to people. A lightning bolt symbol accompanies a danger notice to
represent a dangerous electrical condition. Read and comply with the following
danger notices before installing or servicing this device.
DANGER
To prevent a possible shock from touching two surfaces with
different protective ground (earth), use one hand, when possible, to
connect or disconnect signal cables. (D001)
DANGER
Overloading a branch circuit is potentially a fire hazard and a
shock hazard under certain conditions. To avoid these hazards,
ensure that your system electrical requirements do not exceed
branch circuit protection requirements. Refer to the information
that is provided with your device or the power rating label for
electrical specifications. (D002)
DANGER
If the receptacle has a metal shell, do not touch the shell until you
have completed the voltage and grounding checks. Improper wiring
or grounding could place dangerous voltage on the metal shell. If
any of the conditions are not as described, STOP. Ensure the
improper voltage or impedance conditions are corrected before
proceeding. (D003)
