4.6.2  CN1 & CN2 Shielding Procedure 
The following figure shows the connector shielding procedure for the CN1 or CN2 connector. 
There are two shielding procedures, clamp and soldering processing. 
 
● Clamp processing 
1 
  
 
Remove the cable sheath. 
2 
  
Mount a tape or a compression insert.     
 
At this time, the tape or the compression 
insert should be completely on the cable 
sheath. 
3 
  
 
Fold back the drain wire. 
4 
 
Tighten the cable clamp from on the drain 
wire.   
 
Set it about 1 mm away from the end face 
of the tape or the compression insert. 
 
 
 
 
 
Set the compression insert before soldering the cable to the connector.

  5.1  Servo Amplifier Installation 
Refer to the following for the Servo Amplifier installation place and procedure. 
 
5.1.1 Installation Place 
Install the Servo Amplifier by referring to the following. 
 
Case Precautions 
When installing 
the Servo 
Amplifier in a box The temperature in the box may be higher than the outside temperature depending 
on the power loss of built-in equipment and the dimensions of the box.     
Be sure to keep the temperature around the Servo Amplifier at 55℃  or lower by 
properly determining the dimensions of the box, the cooling system and the 
arrangement. 
For a longer lifetime and higher reliability, operate the Servo Amplifier at an in-box 
temperature of lower than 40°C. 
When there is a 
vibration source 
nearby Install the Servo Amplifier at the base through a shock absorber so that vibration 
may not be transmitted directly to the Servo Amplifier. 
When there is a 
heat generating 
source nearby Even it there is a possibility that a temperature rise may be caused by convection or 
radiation, keep the temperature near the Servo Amplifier lower than 55°C. 
When there is 
corrosive gas If the Servo Amplifier is operated for a long time, contact failure will come to occur at 
contact parts (e.g., connectors).    So, never install the Servo Amplifier in corrosive 
gas atmosphere. 
When there is 
explosive gas or 
combustible gas Never install the Servo Amplifier in explosive gas or combustible gas atmosphere.   
Relays and contactors, which generate arcs (sparks) inside boxes, and such parts 
as regenerative brake resistor may become ignition sources, causing fires and 
explosion. 
When there is 
dust or oil mist Never install the Servo Amplifier in such atmosphere containing dusts or oil mists.   
Dusts or oil mists adhered to or accumulated on the Servo Amplifier may lower 
insulation or cause leak between conductors of applicable parts, damaging the 
Servo Amplifier. 
When there is a 
large noise 
source Induction noise will enter input signals and the power supply circuit, causing Servo 
Amplifier’s malfunction.   
When there is a possibility of noise entering, take proper measures such as inserting 
a noise filter, revising line wiring and preventing noise generation.

5.1.2 Installation Procedure 
●  Direction and Position of Installation 
Install the Servo Amplifier vertically and fix the amplifier by tightening M5 screws onto the four mounting 
holes as in the figure below. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Fig. 5-1 
 
●  Board arrangement conditions 
•  Provide a space of 50 mm at minimum on both upper and lower sides of the Servo Amplifier so as 
not to prevent air from flowing out of the radiator or the amplifier.    If heat remains on the upper part 
of the amplifier, install a fan to force air to flow. 
•  Provide a space of 10 mm at minimum on both sides of the amplifier so as not to prevent radiation 
from the heat sink on the side of the amplifier or air from flowing out of it.

 5.2 Servomotor Installation 
The Servomotor is designed to be installed indoors. 
Note the following precautions on the position and method for installation. 
 
5.2.1 Installation Place 
Install the Servomotor at an indoor site by referring to the following. 
 
•  Ambient temperature  :   0 to 40°C 
•  Storage temperature  :   − 20 to 65°C 
•  Ambient humidity  :   20 to 90% 
•  Well-ventilated places without corrosive or explosive gas 
•  Places free from dust or foreign materials 
•  Places easy to check and clean 
•  Always keep the oil seal lip away from oil or the Servomotor away from a large amount of water, oil or 
cut liquid.    The Servomotor can be protected from slight splashes by means taken on it. 
 
5.2.2 Installation Procedure 
●  Direction of installation 
•  The Servomotor can be installed horizontally or on/under the end of a shaft. 
•  Set the cable from the motor with its end downward. 
•  At vertical installation, provide a cable trap to prevent oily water from going to the motor.

●  Prevention against wetting 
The motor, as a single unit, satisfies the IEC standard.    Since the standard, however, is intended to 
check performance over a short period of time, the following measures against wetting are required for 
actual usage.    Handle the system carefully, or the connector sheathes may be hit or damaged, 
deteriorating waterproof function. 
 
The cannon plug type P1, P2 and P6 as well as the P8 series motor become equivalent to IP67 by using 
a waterproof connector or conduit on the other side of the cannon connector. 
The P3 series motors and the P5 series motors with the flange size of 30 mm and 40 mm sqs. have 
waterproofing equivalent to IP40 and the P5 series motors with the flange size of 50 mm, 70 mm and 80 
mm sqs. to IP55. 
 
•  Set the connector (lead outlet) with its end downward in the angle range shown in the following 
figure. 
•  Install the cover on the side to which water (oil) will splash. 
•  Install the cover with a gradient so that water (oil) may not stay. 
•  Avoid dipping the cable in water (oil). 
•  Slacken the cable outside the cover so that water (oil) may not invade the motor side.

5 - 6  •  When the connector (lead outlet) cannot be installed with its end downward by any means, slacken 
the cable so that water (oil) may not invade it. 
•  Make the oil level of the gear box lower than the oil seal lip. 
•  Provide a vent to prevent the internal pressure of the gear box from rising. 
 
   
 
Fig. 5-7 
 
●  Connection to the opposite machine 
•  Perform centering accurately between the motor shaft and the opposite machine as in Fig. 5-8.   
Note that when a rigid coupling is used, especially, a slight offset will lead to damage of the output 
shaft.

5.  INSTALLATION 
5 - 7  •  Since a precision encoder is directly connected to the motor shaft, be careful not to give shocks to it.   
If tapping on the motor is unavoidable for position adjustment or other reasons, tap on the front 
flange, if possible, with a rubber or plastic hammer. 
 
 
 
•  When installing the motor to the machine, make a installing hole precisely so that the motor joint can 
be smoothly connected.    Also, make the installing surface as flat as possible, or the shaft or the 
bearing may be damaged. 
•  When installing the gear, the pulley, the coupling, etc., avoid giving shocks to them by using the 
screw on the shaft edge. 
 
 
 
•  Since torque is transferred, in the case of the tapered motor shaft, from the tapered surface, take 
care that the key can be engaged without being tapped.   Also, make a hole so that at least 70% of 
the tapered surface is to be engaged. 
•  When removing the gear, the pulley, etc., use a dedicated extracting tool. 
 
 
 
•  When performing belt driving, check that the shaft-converted value of the belt tension does not 
exceed the allowable value shown in Table 5-1. 
 
●  Allowable load of bearing 
Fig. 5-1 shows the load which the Servomotor can endure. 
Do not apply an excessive thrust or radial load. 
The thrust or radial load in the table indicates the value when it is independently applied to the shaft.
