Connecting an Earthing Cable
The BL50S features an earthing stud on the right side of the front panel (see
Figure

). A protective earth connection is
essential for the system to meet its EMC specifications.
Carry out the following steps to connect an earthing cable:
Take an earthing cable with a cross section of at least 0.75 mm².
Slide the cable onto the stud between the washer and the lock washer as indi-
cated in the following picture:
Fasten the cable by tightening the nut.

Electrical Connection
An earthing cable has to be connected to the earthing stud before any
other connections! For disassembling the system, the earthing cable
has to be detached last.
•
Ensure that the box PC is completely configured and mounted
before connecting and applying power to the system.
•
Implement a readily accessible disconnect device external to the
box PC for complying with the EN 60950-1 standard.
•
Make sure that the voltage of the power supply conforms with the
voltage on the type plate.
•
Ensure that the power supply (power socket) is grounded correctly
and that the power cable is intact and undamaged.
•
Do not switch on the system if there are damages on the power
cable or plug.
•
Use power cables which are approved for the power supply in your
country.
•
Power supplies have to be grounded.
