1.3. Safety instructions for installation and maintenance
These warnings and instructions apply to all activities related to the installation, maintenance
and servicing of the HYC_50.
Attention
Failure to follow these instructions may result in serious or fatal injury and
severe property damage.
The installation and maintenance of the HYC_50 rapid charging system
for electric vehicles may only be carried out by qualified personnel.
Before commissioning, check that the system and all connections have
been properly installed.
Electrostatic discharge
The HYC_50 contains components and circuit boards that are sensitive
to electrostatic discharge. Sufficient ESD measures should be taken
during assembly and maintenance to protect the electronic components
(e.g. wearing a grounding arm strap).
Warning of dangerous electrical voltage
Installation and maintenance of the HYC_50 may only be carried out with
the supply voltage switched off. Before installing, dismantling, repairing
or replacing components, the HYC_50 must be disconnected from the
power supply and the main switch in the device must be switched off. In
addition, carry out a voltage check to ensure that the electrical voltage is
disconnected from the system.
Dangerous electrical voltages (up to 1000 VDC) can be present inside
the HYC_50, even if all isolators are switched off.
Care must therefore be taken to ensure that unqualified persons keep
away when the doors of the HYC_50 are open and the discharge time are
observed.
Installation, dismantling, repair or replacement of components of the
HYC_50 must only be carried out by technicians. The door of the HYC_50
enclosure must be properly closed and locked after installation,
maintenance or repair work.
Warning of hot surfaces
Some components inside the HYC_50, such as the power unit,
transformer and cables, may remain hot for a long time after the power
supply has been disconnected.
Before dismantling, repairing or replacing components, ensure that all
components have cooled down.
