converter is not powered. To avoid electrical haz-
ards, stop motor and disconnect:
• AC mains
• Any permanent magnet type motors
• Any remote DC-link power supplies, including
battery backups, ups and DC-link connections to
other frequency converters.
Wait for the capacitors to discharge completely be-
fore performing any service or repair work. Refer to
the following table for wait times:

High voltage may be present even when the warning
LED indicator lights are off.
WARNING:
LEAKAGE CURRENT HAZARD. Follow
national and local codes regarding pro-
tective earthing of equipment with a leak-
age current > 3.5 mA. Frequency con-
verter technology implies high frequency
switching at high power. This will gener-
ate a leakage current in the earth con-
nection. A fault current in the frequency
converter at the output power terminals
might contain a DC component which
can charge the filter capacitors and
cause a transient earth current. The
earth leakage current depends on vari-
ous system configurations including RFI
filtering, screened motor cables, and fre-
quency converter power. Failure to
ground the drive properly could result in
death or serious injury.
EN/EC61800–5–1 (Power Drive System Product
standard) requires special care if the leakage current
exceeds 3.5 mA. Earth grounding must be rein-
forced in one of the following ways:
• Earth ground wire of at least 8 AWG or 10 mm
• Two separate earth ground wires both complying
with the dimensioning rules.
See EN60364–5–54 section 543.7 for further infor-
mation.

UNINTENDED START. Before using the
Genie, set DI18 to Stop (terminal 18
open) to prevent the unit from starting
the motor. Keep terminal 18 open to
avoid an unintended motor rotation. Ap-
ply the Start signal to the controller only
when pump operation is desired.
WARNING:
UNINTENDED START. WINDMILLING!
Unintended rotation of permanent mag-
net motors causes a risk of personal in-
jury and equipment damage. Ensure per-
manent magnet motors are blocked to
prevent unintended rotation.
WARNING:
EQUIPMENT HAZARD. Rotating shafts
and electrical equipment can be hazard-
ous. All electrical work must conform to
national and local electrical codes. Instal-
lation, start-up, and maintenance must
be performed by trained and qualified
personnel. Wear safety glasses whenev-
er working on electric control or rotating
equipment. Failure to follow these guide-
lines could result in death or serious in-
jury.
WARNING:
Only use original spare parts to replace
any worn or faulty components. The use
of unsuitable spare parts may cause
malfunctions, damage, and injuries as
well as void the guarantee.
CAUTION:
INTERNAL FAILURE HAZARD. Risk of
personal injury when the frequency con-
verter is not properly closed. Before ap-
plying power, ensure all safety covers
are in place and securely fastened.
