Connection Of Power Circuit - Mitsubishi Electric LE-50PAU Instruction Manual

4.2 Connection of power circuit

1. Examle of connectiton
Power source
• Apply 85 to 264VDC 50 / 60Hz to the terminal [L] - [N].
The power consumption of the LE-50PAU power amplifier is 400VA.
When a fuse is arranged externally, however, it is advised to secure the fuse capacity of 10A or over,
taking rush current into cinsideration. (The maximum rush current is 50A.)
•
Arrange the emergency stop circuit of the LE-50PAU power amplifire at the outside independent of
tension controller .
If the tension controller is used in a wrong manner of operated erroneously, the LE-50PAU power
amplifire may run away, or other serious accident may occur
•
The LE-50PAU power amplifire is an electronic equipment in which a micro computer (CPU) is
incorporated.
If a conductive foreign matter is mixed in the equipment or any unusual niise is applied from the external
unit, causing the CPU to run away , the watch-dog timer is operated.
•
Execute the solid grounding (grounding resistance : 100Ω or less ) to the earth terminal, using a wire of
2
over 2mm .
In this case, however, be careful not to use the earth commonly to the high power system .
•
Connect the earth terminal of tension controller to that of the LE -50PAU power amplifire to each other ,
and execute the earth at the tension controller side .
•
Ececute the earth for the earth terminals ( for shield wire ) such as [SG], [FG], [SG1], [SG2], etc. at the
same time.
•
The power source of the LE -50PAU power amplifire is prepared commonly for 100VAC and 200VAC.
Connect the power source to across the terminal [L] – [N].
Note that connecting the power wire to the input / output terminal or DC power terminal may cause the
equipment to be broken .
•
Turn ON / OFF the power source of the LE-50PAU power amplifire together with that of tension
controller.
Use a power wire of over 2mm
Class D grounding
( 100Ω or less )
2
to avoid any voltage drop .
