Note 1. The L+ and L- connection conductors used to connect a converter unit to a drive unit are standard accessories. The converter
unit is attached to the drive unit actually. (Refer to section 13.2.1.)
2. The power supply of the servo motor cooling fan differs depending on the capacity of a servo motor. Refer to section 13.3.6.

13.2 Installation
CAUTION
Stacking in excess of the limited number of products is not allowed.
Install the equipment to incombustibles. Installing them directly or close to
combustibles will led to a fire.
Install the equipment in a load-bearing place in accordance with this Instruction
Manual.
Do not get on or put heavy load on the equipment to prevent injury.
Use the equipment within the specified environmental condition range. (For the
environmental conditions, refer to section 13.1.3.)
Provide an adequate protection to prevent screws, metallic detritus and other
conductive matter or oil and other combustible matter from entering the converter
unit
drive unit.
Do not block the intake/exhaust ports of the converter unit drive unit. Otherwise,
a fault may occur.
Do not subject the converter unit drive unit to drop impact or shock loads as they
are precision equipment.
Do not install or operate a faulty converter unit drive unit.
When the product has been stored for an extended period of time, consult
Mitsubishi.
When treating the converter unit drive unit, be careful about the edged parts
such as the corners of the converter unit
drive unit.
POINT
Explanations on the following item are the same as those for servo amplifiers
with 22kW or less. Refer to the section below for details.
Keep out foreign materials Refer to section 2.2.
Cable stress Refer to section 2.3.
SSCNET cable laying Refer to section 2.4.
Parts Having Service Lives Refer to section 2.6.
