2. SAFETY
This manual contains clearly marked warning information which is intended for your personal safe-
ty and to avoid any unintentional damage to the product or connected appliances.
Before installing, commissioning or using the frequency converter, please read the warning in-
formation contained in the corresponding operating guide/installation manual.
Please read the following additional safety instructions carefully.
Only Danfoss authorized, trained and qualified personnel are allowed to install, operate and
maintain the drive.
2.1 Danger
These warnings are intended to personnel responsible for grounding the frequency converter.
2.2 Warnings
Ignoring the following instructions can be extremely dangerous and may cause
death or severe injury.
Ground the frequency converter to ensure personnel safety and to reduce elec-
tromagnetic interference.
After disconnecting the AC drive from the mains or from the DC input supply,
wait until the indicators on the keypad go out (if no keypad is attached, see the
indicators on the cover). Wait an additional 60 seconds before starting any work
on the connections of the drive. After expiration of this time, use measuring
equipment to absolutely ensure that no
voltage is present.
Always ensure absence
of voltage before starting any electrical work!
The touch current of the drive exceeds 3.5 mA AC. According to standard
EN61800-5-1, a reinforced protective ground connection must be ensured. See
the Installation Manual/Operating Guide of your product for further information.
Never work on the photovoltaic generator or frequency converter and its input/
output cables when the frequency converter is connected to the mains or to the
photovoltaic generator.
Before performing any measurement on the frequency converter, disconnect or
isolate the mains supply voltage or the DC input supply.
Do not touch the components on the frequency converter or on the string box
cabinet that have high DC voltage.
The photovoltaic generator cells exposed to light supply DC voltage even at low
light intensity.
