Preparation
> Use only genuine spare parts and accessories.
When using components of other manufacturers the safety and
performance of the equipment as well as the electromagnetic
compatibility of the equipment might be reduced.
Possibly the CE mark or the C/US conformity (see rating plate)
becomes void if not using genuine spare parts.
> Check that the required tools and parts are available and of
the correct type before you start your work.
> Check the operating sequence mentally using exploded view
drawings, spare parts lists and circuit diagram on feasibility,
safety requirements and consequences on safety and func‑
tion of the equipment.
> Vent the device.
> Allow the device to cool down.
> Separate the device from mains prior to maintenance or
repair. Switch off the device and unplug.
> Allow the capacitors to discharge.
> Connect the person in charge to ground prior to any contact
with electronic components to avoid damage from electro‑
static discharges (ESD).
