Notes on safety
The 7LQ3 361 / 362 change-over unit has been built and tested according to
safety specifications. The changeover unit may only be used in perfect technical
condition and for its intended purpose.
However, even if this is the case, the unit may still pose a hazard to users, third
parties and/or property during use.
Any faults that could impair the correct operation of the
changeover unit should therefore be remedied without delay.
Furthermore, no modifications may be made to the
changeover unit. Only original spare parts should be used
during repair work.
All operation and maintenance of the changeover unit may
only be carried out by suitably qualified personnel (who have
read and understood all the safety information contained in
this operating manual).
Always ensure compliance with the correct ratings (voltage, fusing) for the
respective changeover unit. Prior to start-up, always carry out a function test to
check that all connections are correct.
Prior to start-up, carry out a visual inspection to ensure that there are no
obvious signs of damage, any damaged components must be replaced
immediately.
The insulation monitor must be disconnected from the power supply prior to
checking the insulation and voltage.

When selecting a changeover unit, it is essential to
ensure that the switchgear dimensioning is proper
for the facility.
