P30 and S30 Low Voltage VSD

11.3 PRE-POWER UP CHECKS

Perform the following checks before applying any power to the drive.
Potential Severity: Major
Potential Loss: Personnel, Reputation
Hazard Category: Electrical, Explosives
Use appropriate lockout/tag out procedures (refer to SEN-HSE-S027) to ensure that VSD power is OFF
before proceeding with the following checks and procedures.
Use a VOM to verify that ALL power is OFF on the drive, including
•
incoming lines at the bottom of the circuit breaker
•
motor terminals
•
the DC bus
1. The ambient operating conditions meet the specifications.
2. The drive panel has been fixed to wall. If the drive panel is fixed to a stand, the VSD stand has to be
secured to the floor.
3. The cooling air will flow freely in and out of the drive cabinet.
4. If the drive has been stored over one year, the electrolytic DC capacitors in the DC link of the drive have
been reformed.
5. There is an adequately sized protective earth (ground) conductor between the drive and the
switchboard, and the conductor has been connected to appropriate terminal, and the terminal has been
tightened. (Pull the conductor to check.) Proper grounding has also been measured according to the
regulations.
6. The input power cable has been connected to the appropriate terminals, the phase order is right, and the
terminals have been tightened. (Pull the conductors to check.)
7. There is an adequately sized protective earth (ground) conductor between the motor and the drive, and
the conductor has been connected to appropriate terminal, and the terminal has been tightened. (Pull on
the conductors to check.) Proper grounding has also been measured according to the regulations.
8. The motor cable has been connected to the appropriate terminals, the phase order is right, and the
terminals have been tightened. (Pull on the conductors to check.)
9. The motor cable (and brake resistor cable if present) has been routed away from other cables.
10. No power factor compensation capacitors have been connected to the motor cable.
11. The control cables have been connected to the appropriate terminals, and the terminals have been
tightened. (Pull on the conductors to check.)
12. The supply voltage matches the nominal input voltage of the drive. Check the type designation label.
13. The voltage setting of the Control Power Transformers is correct.
14. The power jumper configuration is correct to the type of power source. (Refer to
Configuration.)

11.4 DRIVE RESET

11.4.1 RESETTING THE DRIVE/ PERIPHERALS

The drive or any of its connected peripherals can be reset by removing and restoring power to the drive
(power cycling). If this is not convenient or cannot be done because of application circumstances, the HIM
can be used to reset the drive/peripherals. Follow these steps to reset the drive or any of its peripherals.
