WARNING
INTERNAL FAILURE HAZARD
Under certain circumstances, an internal failure can
cause a component to explode. Failure to keep the
enclosure closed and properly secured can cause death
or serious injury.
•
Do not operate the drive with the door open or
panels oîš„.
•
Ensure that the enclosure is properly closed and
secured during operation.
WARNING
SHOCK HAZARD
The drive can cause a DC current in the protective earth/
ground (PE) conductor and thus result in death or
serious injury.
•
When a residual current-operated protective
device (RCD) is used for protection against
electrical shock, only an RCD of Type B is
permitted on the supply side.
Failure to follow the recommendation means that the
RCD cannot provide the intended protection.
CAUTION
RISK OF INJURY OR PROPERTY DAMAGE
Do not assume that a motor is wired properly after
completed service of the drive. Failure to perform these
checks can result in personal injury, property damage, or
less than optimal performance.
Check for:
•
Loose connections.
•
Improper programming.
•
Added equipment.
CAUTION
HOT SURFACES
The drive contains metal components that are still hot
even after the drive has been powered oîš„. Failure to
observe the high temperature symbol (yellow triangle)
on the drive can result in serious burns.
•
Be aware that internal components, such as
busbars, can be extremely hot even after the
drive has been powered oîš„.
•
Exterior areas marked by the high-temperature
symbol (yellow triangle) are hot while the drive
is in use and immediately after being powered
oîš„.
NOTICE
MAINS SHIELD SAFETY OPTION
A mains shield option is available for enclosures with a
protection rating of IP21/IP54 (UL type 1/12). The mains
shield is a cover installed inside the enclosure to protect
against the unintended touch of the power terminals,
according to BGV A2, VBG 4.
NOTICE
LIFTING - EQUIPMENT DAMAGE RISK
Incorrect lifting can result in equipment damage.
•
Use lifting lugs where provided.
•
Prevent uncontrolled rotation.
2.5 Electrostatic Discharge
NOTICE
STATIC DISCHARGE
When performing service, use proper Electrostatic
Discharge (ESD) procedures to prevent damage to
sensitive components.
NOTICE
AVOID TOUCH
Do not touch components on the circuit boards. Hold
circuit boards by the corners and edges only.
Many electronic components within the drive are sensitive
to static electricity. Voltages so low that they cannot be
felt, seen, or heard can reduce the life, aîš‚ect performance,
or completely destroy sensitive electronic components.
