Safety
Safety Regulations
1. The adjustable frequency drive must be disconnected from line power if repair work is to be carried out.
Make sure that the line power supply has been disconnected and that the necessary time has passed before
removing motor and line power plugs.
2. The [STOP/RESET] key on the keypad of the adjustable frequency drive does not disconnect the equipment
from line power and is thus not to be used as a safety switch.
3. Correct protective grounding of the equipment must be established, the user must be protected against
supply voltage, and the motor must be protected against overload in accordance with applicable national
and local regulations.
4. The ground leakage currents are higher than 3.5 mA.
5. Protection against motor overload is set by par.1-90
set par.1-90 Motor Thermal Protection
Note: The function is initialized at 1.16 x rated motor current and rated motor frequency. For the North
American market: The ETR functions provide class 20 motor overload protection in accordance with NEC.
6. Do not remove the plugs for the motor and line power supply while the adjustable frequency drive is con-
nected to line power. Make sure that the line power supply has been disconnected and that the necessary
time has passed before removing motor and line power plugs.
7. Please note that the adjustable frequency drive has more voltage inputs than L1, L2 and L3, when load
sharing (linking of DC intermediate circuit) and external 24 Vdc have been installed. Make sure that all
voltage inputs have been disconnected and that the necessary time has passed before commencing repair
work.
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.
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.
WARNING
Touching the electrical parts could result in death or serious injury - even after the equipment has been disconnected
from line power.
