Xylem hydrovar User Manual

Air pollution The air may contain dry dust as found in workshops where there is
excessive dust due to machines. Excessive amounts of dust, acids,
corrosive gases, salts etc are not permitted.
Altitude Max. 1000 m above sea level. For installation over 1000 m above sea
level, the maximum output power has to be de-rated by 1% for every
additional 100 m. If the installation site is over 2000 m above sea
level, please contact your local distributor or service contact.
Installation specification
Protection Motor drive input have to be protected by an external circuit breaker/
fuse
Motor wire type shielded power cable
Maximum motor cable length (no EMC compliant), screened 50m (164ft)
Maximum motor cable length (no EMC compliant), unscreened 100m (328ft)
EMC compliance
In accordance with IEC 61800-3 and EN 61000 series standards, shield cable will be used
for motor drive output and communication.
Installations must be done according EMC correct installations and avoiding pigtails (on
the drive side), otherwise EMC cannot be guaranteed.
Class of protection
• IP55, Enclosure Type 1
• Protect the product from direct sunlight
• Protect the product from direct rainfall
• Outdoor installation without protection, to especially keep the temperature limits of
the product, is not permitted
3.6 Motor thermal protection
Motor thermal protection can be implemented using various techniques: PTC sensor in
motor windings or Software Thermal Control (STC).
Protection against motor overheating comes from par. 290 "STC Motor Protection", which
by default is pre-sett to data value "STC trip".
NOTICE: The STC function is initialized at 1.125 x rated motor current and rated motor
frequency. The STC function provides class 20 motor overload protection in accordance
with the NEC.
Motor thermal protection prevents the motor from overheating. The STC function is an
electronic feature that simulates a bimetal relay that is based on internal measurements.
The characteristic is shown in the following figure.
