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.

13.2.2 Inspection
WARNING
Before starting maintenance and/or inspection, turn off the power and wait for 20
minutes or more until the charge lamp turns off. Then, confirm that the voltage
between L
and L is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always confirm from the front of the converter
unit whether the charge lamp is off or not.
CAUTION
Any person who is involved in inspection should be fully competent to do the work.
Otherwise, you may get an electric shock. For repair and parts replacement,
contact your safes representative.
POINT
Do not test the converter unit drive unit with a megger (measure insulation
resistance), or it may become faulty.
It is recommended to make the following checks periodically.
1) Check for loose terminal block screws. Retighten any loose screws.
2) Check the servo motor bearings, brake section, etc. for unusual noise.
3) Check the cables and the like for scratches and cracks. Perform periodic inspection according to operating
conditions.
4) Check the servo motor shaft and coupling for misalignment.
