General rules for operating the SIMOTION D410-2

When integrating the SIMOTION D410-2 into a system, you must observe the following general
rules.
System startup after certain events
Observe the following rules when starting up a system following certain events:
● During startup after a voltage dip or power failure, no dangerous operating states may
result. If necessary, force an EMERGENCY STOP.
● At startup, after unlocking the EMERGENCY STOP apparatus, there must not be an
uncontrolled or undefined startup.
Supply voltage
Observe the following rules for the supply voltage:
● For stationary installations or systems that do not have all-pole line disconnect switches,
the building installation must include a line side switch or a fuse.
● For load power supplies and power supply modules, the rated voltage range set must
correspond to the local line voltage.
● For all electrical circuits, the fluctuation/deviation of the line voltage from the rated value
must be within the permitted tolerance (refer to the technical data of the used components)
24 V DC supply voltage
Observe the following rules for the 24 V supply:
● Provide lightning protection (e.g. lightning protection devices):
– External lightning protection is required for buildings.
– An internal lightning protection must be provided for for 24 V DC supply cables and
● Ensure safe (electrical) isolation of the extra-low voltage for the 24 V supply.
Danger to life from hazardous voltage when connecting an unsuitable power supply
Implement the 24 V DC supply with protective separation as protective extra-low voltage.
