4. Installation / wiring
4.1 Installation dimension / wiring work
1. Installation dimension
Install and fix the LE-50PAU power amplifier at the inside of panel, using
•
the fixing holes ( φ4.5 ) prepared at four corners.
The LE-50PAU power amplifier is provided with a groove at the bottom
•
surface to avoid the DIN rail, however, it is unable to fit the LE-50PAU
power amplifire to the DIN rail.
•
Do not install the LE -50PAU power amplifire on the floor surface , for prevention of temperature rize, but
be sure to install it directly to the sheet metal part on the wall surface .
•
Secure a space of over 100mm between each unit of between the eqipment and other eqipment or
structure. Keep the eqipment isolated from the high -voltage wire, high- voltage unit or power unit .
2. wiring work
• Use the crimp-style terminals. Dimensions shown in the right figure.
• Tighten the terminal securely at a torque of 0.5 to 0.8 N•m, so that any mal-
function should not be generated.
• Do not connect the wire to the empty terminal [ • ] at the outside.
• Use a shield wire for analog input wire.
• Do not attempt to execute the input / output wiring in the same duct as that
used for other power wire, or to bind such wire together with the other pow-
er wiere.
• A connection example for analog input is as shown on page 15.
• There is not any problen even if the input wiring is extended up to approx. several dozens of meters in
accordance with the precautions (shown at avobe ), however, it is generally advised to execute the wir-
ing up to within 20m, taking safety against noise into consideration.
• Use a small signal switch for contact input, which is suitable to a small current of 12VDC 5mA,
•
To execute the installation / wiring work, be sure to shut off all phases of power source externally in
advance.
•
Do not install the LE -50PAU power amplifire at a place of dust , oil mist, conductive dust, corrosive gas or
iflammable gas.
•
Do not install the LE -50PAU power amplifire directly at a place where vibration or shock is applied .
•
Do not install the LE -50PAU power amplifire at a place which may be exposed to high - temperature,
dewing or rain / wind.
•
To execute the drilling or wiring , be careful not to allow the cutting chip or wire chip to drop .
•
Since the case is made of aluminum die cast , the surface may reach high temperature during operation .
Since this may cause the operator to get burned , use such installation method that will not allow the body
to make direct contact with the surface of case.
--------- The genaral external connection is shown on page 8.
