Safety Notes
Personal Injury or System Damage (For DC)
The system is supplied by a TNV-2 voltage. This voltage is considered hazardous. Make sure
that the power supply meets the relevant safety standards.
Ensure that TNV-2 is separated from dangerous voltages (mains) through double or reinforced
insulation.
Personal Injury or System Damage
A top-heavy rack can topple over, causing damage to equipment and injury to personnel.
If your system is the only one in the rack, make sure to mount the system in the lowest part of
the rack. If several systems are installed in one rack, start with the heaviest component at the
bottom. If the rack is equipped with stabilizing devices, make sure that they are installed and
extended so that the rack is secure. Then proceed to mount or service the system.
Personal Injury or System Damage
When pulling the system out of the rack, it can fall down and cause injuries.
Pull out the system cautiously.

items can become loose or damaged.
