The following table identifies considerations required for startup of a system following certain
events.
Table 6-1
System startup
When ... then ...
Startup after voltage drop or power loss no dangerous states must result. If necessary, force an
EMERGENCY OFF.
Startup after releasing the EMERGENCY
OFF equipment
uncontrolled or undefined startup operations must be
excluded.
Supply voltage
The following table identifies the considerations required for the supply voltage.
Table 6-2
Supply voltage
When ... make sure that ...
Stationary systems or systems
without all-pole power disconnect
switches
the building installation must be equipped with a power
disconnect switch or a fuse.
Load power supply, power supply
modules
the set range of the rated voltage complies with the local mains
voltage.
All electric circuits deviation of the line voltage from the rated value must be within
the
permitted tolerance (refer to "Technical data of the installed
components").
24 V DC supply voltage
The following table identifies the considerations required for the 24 V supply voltage.
Table 6-3
24 V DC supply voltage
When ... ensure ...
Buildings External lightning
protection
Provide lightning protection (e.g.,
lightning protection devices)
24 V DC supply voltage cables,
signal cables
internal lightning
protection
24 V supply voltage safe (electrical) isolation of the extra-low voltage
WARNING
Danger to life from hazardous voltage when connecting an unsuitable power supply
Configure the 24 V DC voltage as a protective extra-low voltage (PELV according to
DIN EN 60204-1).
