1.1.1 Warnings

WARNING
HIGH-VOLTAGE WARNING
The voltage of the frequency converter is dangerous
whenever it is connected to mains. Incorrect installation
of the compressor or frequency converter may cause
death, serious injury, or equipment damage. To avoid
death, serious injury, or equipment damage:
•
Comply with the instruction in this manual as
well as local and national rules and safety
regulations.
WARNING
DISCHARGE TIME!
Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is
not powered. To avoid electrical hazards, disconnect AC
mains, any permanent magnet type compressors, and
any remote DC-link power supplies, including battery
back-ups, UPS, and DC-link connections to other
frequency converters. Wait for the capacitors to fully
discharge before performing any service or repair work.
The waiting time is listed in Table 1.1. Failure to wait the
specified time after power has been removed before
doing service or repair could result in death or serious
injury.

CAUTION
Leakage Current
The ground leakage current from the frequency
converter exceeds 3.5 mA. According to IEC 61800-5-1 a
reinforced protective earth connection must be ensured
with a minimum 10 mm
same cable cross-section as the mains wiring. Terminate
the PE connection separately.
Residual Current Device
This product can cause a DC current in the protective
conductor. Where a residual current device (RCD) is used
for extra protection, only an RCD of Type B (time
delayed) shall be used on the supply side of this
product. See also Danfoss Application Note on RCD.
Protective earthing of the frequency converter and the
use of RCDs must always follow national and local
regulations.
NOTICE
INSTALLATION AT HIGH ALTITUDES
For altitudes above 2000 m, contact Danfoss regarding
PELV.

1.1.2 Safety Instructions
