5.1 Safety Instructions
See
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 qualified
personnel could result in death or serious injury.
•
Installation, start-up, and maintenance must be
performed by qualified personnel only.
Before applying power:
1.
Close the cover properly.
2.
Check that all cable connectors are firmly
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.
Confirm 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.
Confirm that the supply voltage matches the
voltage of the adjustable frequency drive and the
motor.
5.2 Applying Power
Apply power to the adjustable frequency drive using the
following steps:
1.
Confirm that the input voltage is balanced within
3%. If not, correct the input voltage imbalance
before proceeding. Repeat this procedure after
the voltage correction.
2.
Ensure that any optional equipment wiring,
matches the installation application.
3.
Ensure that all operator devices are in the OFF
position. Panel doors must be closed and covers
securely fastened.
4.
Apply power to the unit. DO NOT start the
adjustable frequency drive now. For units with a
disconnect switch, turn it to the ON position to
apply power to the adjustable frequency drive.
5.3 Local Control Panel Operation
5.3.1 Local Control Panel
The local control panel (LCP) is the combined display and
keypad on the front of the unit.
The LCP has several user functions:
•
Start, stop, and control speed when in local
control.
•
Display operational data, status, warnings and
cautions.
•
Program adjustable frequency drive functions.
•
Manually reset the adjustable frequency drive
after a fault when auto-reset is inactive.
An optional numeric LCP (NLCP) is also available. The NLCP
operates in a manner similar to the LCP. See the product
relevant
programming guide
for details on use of the NLCP.
NOTICE!
