Danfoss VLT AutomationDrive FC 302 Installation Manual

5 Start-up and Functional Testing
5.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
WARNING
HIGH VOLTAGE
Adjustable frequency drives contain high voltage when
connected to AC line input power. Failure to perform
installation, start-up, and maintenance by qualied
personnel could result in death or serious injury.
•
Installation, start-up, and maintenance must be
performed by qualied personnel only.
Before applying power:
1. Close the cover properly.
2. Check that all cable connectors are rmly
tightened.
3. Ensure that input power to the unit is OFF and
locked out. Do not rely on the adjustable
frequency drive disconnect switches for input
power isolation.
4. Verify that there is no voltage on input terminals
L1 (91), L2 (92), and L3 (93), phase-to-phase, and
phase-to-ground.
5. Verify that there is no voltage on output
terminals 96 (U), 97 (V), and 98 (W), phase-to-
phase, and phase-to-ground.
6.
Conrm continuity of the motor by measuring Ω
values on U-V (96-97), V-W (97-98), and W-U
(98-96).
7. Check for proper grounding of the adjustable
frequency drive as well as the motor.
8. Inspect the adjustable frequency drive for loose
connections on the terminals.
9. Conrm that the supply voltage matches the
voltage of the adjustable frequency drive and the
motor.
5.1.1 Pre-start
CAUTION
Before applying power to the unit, inspect the entire installation as detailed in Table 5.1. Check mark those items when
completed.
Inspect for Description
☑
Auxiliary equipment
•
Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers on the input
power side of the adjustable frequency drive or output side to the motor. Ensure that they are ready
for full speed operation.
•
Check function and installation of any sensors used for feedback to the adjustable frequency drive.
•
Remove power factor correction caps on motors, if present
Cable routing
•
Use separate metallic conduits for each of the following:
•
input power
•
motor wiring
•
control wiring
Control wiring
•
Check for broken or damaged wires and loose connections.
•
Check that control wiring is isolated from power and motor wiring for noise immunity.
•
Check the voltage source of the signals, if necessary.
•
The use of shielded cable or twisted pair is recommended. Ensure that the shield is terminated
correctly.
Cooling clearance
•
Make sure that the top and bottom clearance is adequate to ensure proper airow for cooling.
