Safety instructions for assembly/installation
DANGER
Live components
Danger to life and limb.
Work on electric equipment may only be carried out by qualified specialist personnel ( "Definition of person‐
nel", Page 7) in compliance with the safety regulations.
–
It must be possible to switch off the power supply by means of a device to disconnect the power supply
(e.g. mains connection or isolating switch with a padlock).
–
Switch off the electric power supply before starting work. The mains connection or isolating switch must be
protected against unauthorised or accidental restoration of the power supply by means of a padlock. Dan‐
gerous voltages can still be present for some time (wait at least 3 minutes) after switching off the
power supply.
WARNING
Inappropriate assembly and installation work
Danger to life and limb. Risk of material damage.
Assembly and installation work may only be carried out by authorised, trained specialist personnel ( "Definition
of personnel", Page 7) in compliance with all safety regulations.
–
Secure and fence off the working area and danger zone.
–
If an elevating work platform is used for assembly and installation work, only use appropriate attachments
for the lifting of persons which ensure that work is carried out in a safe and stable position.
–
Only suitable, tested and calibrated tools and accessories may be used for assembly and installation work.
–
Only use approved spare parts, see also "Use of spare parts", Page 7.
–
Wear protective equipment, see also "Personal protection equipment", Page 13.
–
Be careful when working on open components that have sharp edges. Risk of injury.
–
Keep the working area clean and tidy. Store any machine parts or fittings and tools that are not needed in
such a way that there is no risk of them falling.
–
Fit components correctly and as intended. Comply with specified bolt tightening torques. Incorrectly fitted
components can fall and cause severe injuries.
–
Customer-specific regulations must be observed.
6.2
Fitting the hardware modules
General installation instructions
CM communication modules and EM extension modules are supplied pre-assembled in an enclosure. They are
installed in slots B and C, "Hardware modules", Page 50.
DANGER
Electric shock, live components
Contact with live components may result in danger to life and limb.
The inverter must be disconnected from the power supply before any hardware is fitted. Modules must not be
fitted when the inverter is connected to a power supply as the inverter and/or the hardware modules will other‐
wise be destroyed.
Wait at least 5 minutes after disconnecting from the line supply before starting any installation work.
The PCB visible on the rear must not be touched, as parts can be damaged.
