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 power. Failure to perform instal-
lation, 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 o 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.
5.2
Applying Power
Apply power to the adjustable frequency drive using the
following steps:
1. Conrm 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
The adjustable frequency drive supports numerical local
control panel (LCP) graphic local control panel (GLCP) and
blind cover. This chapter describes the operations with LCP
and GLCP.
NOTICE!
The adjustable frequency drive can also be programmed
from the MCT 10 Set-up Software on PC via RS485
communication port. This software can be ordered using
code number 130B1000 or downloaded from the Danfoss
website: www.danfoss.com/BusinessAreas/DrivesSolutions/
softwaredownload.
5.3.1 Local Control Panel (LCP)
The numerical local control panel (LCP) is divided into four
functional sections.
A. Numeric display.
B. Menu key.
C. Navigation keys and LEDs.
D. Operation keys and LEDs.
