Safety
Definitions and symbols
WARNING
This symbol indicates high voltage. It calls your attention
to items or operations that could be dangerous to you
and other persons operating this equipment. Read the
message and follow the instructions carefully.
This symbol is the "Safety Alert Symbol. " It occurs with
either of two signal words: CAUTION or WARNING, as
described below.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, can result in serious injury or death.
Indicates a potentially hazardous situation which, if not
avoided, can result in minor to moderate injury, or serious
damage to the product. The situation described in the
CAUTION may, if not avoided, lead to serious results.
Important safety measures are described in CAUTION (as
well as WARNING).
Hazardous High Voltage
WARNING
Motor control equipment and electronic controllers are
connected to hazardous line voltages. When servicing
drives and electronic controllers, there may be exposed
components with housings or protrusions at or above
line potential. Extreme care should be taken to protect
against shock.
Stand on an insulating pad and make it a habit to use only
one hand when checking components. Always work with
another person in case an emergency occurs. Disconnect
power
before
checking
maintenance. Be sure equipment is properly grounded. Wear
safety glasses whenever working on electronic controllers or
rotating machinery.

Warnings and cautions
This manual contains clearly marked cautions and warnings
which are intended for your personal safety and to avoid any
unintentional damage to the product or connected
appliances.
Please read the information included in cautions and
warnings carefully.
Warnings
WARNING
Be sure to ground the unit following the instructions
in this manual. Ungrounded units may cause electric
shock and/or fire.
WARNING
This equipment should be installed, adjusted, and
serviced by qualified electrical maintenance personnel
familiar with the construction and operation of this type
of equipment and the hazards involved. Failure to
observe this precaution could result in death or severe
injury.
WARNING
Components within the SC9000 EP power unit are live
when the drive is connected to power. Contact with this
voltage is extremely dangerous and may cause death or
severe injury.
WARNING
Line terminals (L1, L2, L3), motor terminals (U, V, W) and
the DC-link terminals (-/+/N) are live when the drive is
connected to power, even if the motor is not running.
Contact with this voltage is extremely dangerous and
may cause death or severe injury.
WARNING
Even though the control I/O-terminals are isolated from
line voltage, the relay outputs and other I/O-terminals
may have dangerous voltage present even when the
drive is disconnected from power. Contact with this
voltage is extremely dangerous and may cause death or
severe injury.
WARNING
The SC9000 EP drive has a large capacitive leakage
current during operation, which can cause enclosure
parts to be above ground potential. Proper grounding, as
described in this manual, is required. Failure to observe
this precaution could result in death or severe injury.
