VACON® 1000
Operating Guide
8 Commissioning
8.1 Safety Checks before Starting the Commissioning
Only qualified and trained engineers authorized by Danfoss are allowed to do the commissioning of the VACON® 1000 medium-
voltage drive.
Functional tests, commissioning, and primary parameter calibration must be executed by professional engineers in coordination
with the end users to make sure that the final test and performance are according to the end users requirements.
Before starting the commissioning, read these warnings.
SHOCK HAZARD FROM POWER UNIT COMPONENTS
The power unit components are live when the drive is connected to mains. A contact with this voltage can lead to death or seri-
ous injury.
-
Do not touch the components of the power unit when the drive is connected to mains. Before connecting the drive to mains,
make sure that the covers of the drive are closed.
SHOCK HAZARD FROM TERMINALS
The motor terminals U, V, W are live when the drive is connected to mains, also when the motor does not operate. A contact with
this voltage can lead to death or serious injury.
-
Do not touch the motor terminals U, V, W when the drive is connected to mains. Before connecting the drive to mains, make
sure that the covers of the drive are closed.
SHOCK HAZARD FROM DC LINK OR EXTERNAL SOURCE
The terminal connections and the components of the drive can be live several minutes after the drive is disconnected from the
mains and the motor has stopped. The load side of the drive can also generate voltage. A contact with this voltage can lead to
death or serious injury.
-
Disconnect the drive from the mains and make sure that the motor has stopped.
Disconnect the motor.
Lock out and tag out the power source to the drive.
Make sure that no external source generates unintended voltage during work.
To ground the drive input and DC link, close the grounding switch. If there is no grounding switch, make sure that the drive
input and DC link are grounded for work. Also ground the motor terminals for work.
Wait for the DC-link capacitors to discharge fully before opening the cabinet door or the cover of the AC drive.
Use a measuring device to make sure that there is no voltage.
8.2 Personnel Requirements
At least two professional electrical technicians are necessary as the operators for commissioning. The operators must meet the fol-
lowing conditions.
•
Must be familiar with the low, medium, and high-voltage electrical equipment and the related safety regulations.
•
Must be familiar with the distribution system on site.
•
Must be authorized to operate low and medium-voltage equipment (high-voltage power breaker and other medium and low-
voltage transmission switches).
•
Must be authorized to operate the distribution equipment in the premises.
8.3 Commissioning Checks
After the VACON® 1000 is installed, follow these instructions to commission the AC drive.
