Installation at high altitudes
WARNING
Installation at high altitude:
380 - 500 V, enclosure A, B and C: At altitudes above 2 km (6,561 ft), please contact Trane regarding PELV/Class II.
380 - 500 V, enclosure D, E and F: At altitudes above 3 km (9,842 ft), please contact Trane regarding PELV/Class II.
If the drive is to be installed over 2000m (6,561 ft) altitude, then the PELV specifications are not fulfilled anymore, i.e.
the distances between components and critical parts become too small. To keep anyway the clearance for functional
insulation, the risk for over-voltage must be reduced by means of external protective devices or kind of galvanic isolation.
De-rating should also be taken into consideration, as cooling of the drive is not so effective at high altitude. Please
contact Trane in such cases.
Failure to follow recommendations could result in death or serious injury.
WARNING
Warning against Unintended Start
1.
The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop,
while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure
that no unintended start occurs, these stop functions are not sufficient.
2.
While parameters are being changed, the motor may start. Consequently, the stop key [STOP/RESET] must always
be activated; following which data can be modified.
3.
A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a
temporary overload or a fault in the supply mains or the motor connection ceases.
Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be inadvertently energized. Failure to follow recommendations could
result in death or serious injury.
WARNING
Touching the electrical parts could result in death or serious injury - even after the equipment has been disconnected
from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 Vdc, load sharing (linkage
of DC intermediate circuit), as well as the motor connection for kinetic back up. Refer to the Operating Instruc-
tions for further safety guidelines.
Failure to follow recommendations could result in death or serious injury.
WARNING
The frequency converter DC link capacitors remain charged after power has been disconnected. To avoid an electrical
shock hazard, disconnect the frequency converter from the mains before carrying out maintenance. Wait at least as
follows before doing service on the frequency converter:
Failure to follow recommendations could result in death or serious injury.
