2.7 RESIDUAL RISKS
Residual risks are the risks that remain after all relevant safety standards have been complied with. These
have been evaluated in the form of a risk assessment. Residual risks associated with assembly and instal-
lation of DMUI-HSM Handsets are listed here and throughout this Operating Manual. The risks associ-
ated with the system as a whole are listed in the System Manual. See also Chapter 1.1 Other Applicable
Documents on page 5. The symbols and signal words used in this Operating Manual are listed in Chapter 2.5
Explanation of Symbols and Signal Words on page 7.
WARNING Risk of death or serious injury through electric shocks
The DMUI-HSM is an electrical device. Although you will not have to connect any prod-
ucts to the Power Unit during assembly, basic safety precautions must be taken at all
times. Failure to observe electrical safety precautions may lead to death or serious inju-
ry through electric shocks.
• Never open a DMUI-HSM Handset
• Ensure that the product is not connected to the Power Unit during assembly
• Do not convert or modify the DMUI-HSM Handset in any way
• Do not immerse the DMUI-HSM Handset or its components in liquid. Clean only
with a dry or slightly damp cloth
• Do not place the Cable of the DMUI-HSM Handset on heated surfaces
• Check the housing and cables of the DMUI-HSM Handset for visible damage. Do
not install or operate damaged products
WARNING Risk of death or serious injury in explosive atmospheres
Operating the Handset in potentially explosive atmospheres may lead to death or seri-
ous injury through explosions.
• Read the relevant directives to determine if an atmosphere is potentially explosive
• Do not operate the Handset in potentially explosive atmospheres
CAUTION
Risk of minor or moderate injury through tripping
During the assembly process, you may have to step over Cables. Tripping over Cables
may lead to minor or moderate injury.
• Ensure that the assembly area is kept clear of unnecessary obstructions
• Be careful not to trip over Cables
CAUTION
Risk of minor or moderate injury through crushing
If any Handset Key becomes stuck while the system is in motion, the system may not
