Installation at high altitudes
WARNING
Installation at high altitude:
380–500 V, enclosure A, B and C: At altitudes above 6,561 ft [2 km], please contact Trane regarding PELV/Class II.
380–500 V, enclosure D, E and F: At altitudes above 9,842 ft [3 km], please contact Trane regarding PELV/Class II.
If the drive is to be installed over 6,561 ft [2 km] altitude, then the PELV specifications are not fulfilled anymore, i.e.,
the distances between components and critical parts become too small. To maintain the clearance for functional insu-
lation anyway, the risk for overvoltage must be reduced by means of external protective devices or some kind of galvanic
isolation. De-rating should also be taken into consideration, since cooling the drive is more difficult 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 adjustable frequency drive is connected to line power. 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 adjustable frequency drive, or if a
temporary overload or a fault in the supply line power or the motor connection ceases.
Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot 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 line power.
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 backup. Refer to the Instruction Manual
for further safety guidelines.
Failure to follow recommendations could result in death or serious injury.
WARNING
The adjustable frequency drive DC link capacitors remain charged after power has been disconnected. To avoid an
electrical shock hazard, disconnect the adjustable frequency drive from line power before carrying out maintenance.
Wait at least as follows before doing service on the adjustable frequency drive:
Failure to follow recommendations could result in death or serious injury.
