Definitions And Symbols; Hazardous High Voltage; Warnings And Cautions - Eaton PowerXL DG1 Series VFD Communications Manual

Read this manual thoroughly and make sure you understand
the procedures before you attempt to install, set up, operate
or carry out any maintenance work on this DG1 Adjustable
Frequency Drive.

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 controllers or
●
performing maintenance.
Be sure equipment is properly earthed.
●
Wear safety glasses whenever working on electronic
●
controllers or rotating machinery.
CAUTION
The components in the drive's power section remain
energized after the supply voltage has been switched off.
After disconnecting the supply, wait at least five minutes
before removing the cover to allow the intermediate
circuit capacitors to discharge.
Pay attention to hazard warnings!
DANGER
5 MIN
Electric shock hazard—risk of injuries! Carry out wiring
work only if the unit is de-energized.
Do not perform any modifications on the AC drive when
it is connected to mains.

Warnings and Cautions

Be sure to ground the unit following the instructions in
this manual. Ungrounded units may cause electric shock
and/or fire.
This equipment should only 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.
Components within the drive are live when it is connected
to power. Contact with this voltage is extremely
dangerous and may cause death or severe injury.
Line terminals (L1, L2, L3), motor terminals (U, V, W) and the
DC link/brake resistor terminals (DC–, DC+/R+, R–) 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.
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.
