Electrical Installation of MOVIMOT® Standard Design
Connecting
24V
DC
supply
•
Supply MOVIMOT
®
either via external 24 V
DC
or via the MLU..A or MLG..A options.
Conventional
control (via
binary com-
mands)
•
Connect the required control leads (e.g. CW/Stop, CCW/Stop, f1/f2 setpoint change)
•
Use shielded cables as control leads and route them separately from power supply
cables.
Control via
RS-485 interface
with bus master PLC, MLG..A, MBG11A, MWA21A option or MF../MQ.. fieldbus inter-
faces
•
Important: Connect only one bus master.
•
Use twisted pair shielded cables as control leads and route them separately from
power supply cables.
Protection
devices
•
MOVIMOT
®
drives are equipped with integrated protective overload devices that are
making external overload devices obsolete.
UL compliant
installation
•
Only use copper cables with the temperature range 60/75 °C as connection lead:
•
The permitted tightening torques for MOVIMOT
®
power terminals are:
– 1.5 Nm (13.3 lb.in).
•
MOVIMOT
®
are suited for operation on voltage supply systems with grounded star
(TN and TT systems) supplying a maximum supply current of 5000 A
AC
and having
a maximum rated voltage of 500 V
AC
(MM03C-503 to MM3XC-503). The perfor-
mance data of the fuses must not exceed 35 A/600 V.
•
Only use tested units with a limited output voltage (V
max
= 30 V
DC
) and limited output
current (I
≤
8 A) as an external 24 V
DC
voltage source.
•
UL certification applies only to operation in voltage supply systems with voltages to
ground up to 300 V.
