Installation Environment
Do not use this product in the following environment:
• Location where the surrounding air temperature exceeds the range of 0 to 40°C
• Location where condensation occurs due to abrupt temperature changes
• Location where relative humidity smaller than 30% or larger than 95%RH
• Location exposed to corrosive gases or combustible gases
• Location exposed to significant amount of dust, salt or iron powder
• Location subject to direct vibration or impact
• Location exposed to direct sunlight
• Location where the product may come in contact with water, oil or chemical droplets
When using the product in any of the locations specified below, provide a
sufficient shield.
• Location subject to electrostatic noise
• Location where high electrical or magnetic field is present
• Location with the mains or power lines passing nearby
Installation and Noise Elimination
1. Noise Elimination Grounding (Frame Ground)
2. Precautions Regarding Wiring Method
• Use a twisted cable for connection to power supply
• Separate the I/O line, communication line and power or driving line to each other.
3. Noise Sources and Elimination
Carry out noise elimination measures for power devices on the
same power path and in the same equipment.
The following are examples of measures to eliminate noise
sources:
①
AC solenoid valves, magnet switches and relays
[Measure]
Install a noise killer parallel with the coil.
②
DC solenoid valves, magnet switches and relays
[Measure]
Install a diode parallel with the coil. Use a
DC relay with a built-in diode.
4. Heat Radiation and Installation
Conduct design and manufacture in consideration of the control box size, controller layout
and cooling in such a way that the temperature around the controller will be 40
°C or less.
Connection Diagram
*1 When the PC is connected to the controller using the USB cable, it is required to attach
the dummy plug to the controller to short circuit the Safety Gate Signal for the PC
application software and teaching pendant.
*2 It shows an example of PIO interface. In the case of field bus type (DeviceNet, CC-Link or
ProfiBus), the field bus connector (For Device Net, CC-Link or ProfiBus) should be used.
Warning When the PC is connected to the controller using the USB cable, the emergency stop
box can not be connected. In the case of stop in an emergency, process it in the system.
Wiring for the Power/Emergency Stop Circuit and Brake Forced Release Switch
• SSEL Controller Power Supply Wiring (The Client should prepare it).
*1 Make sure to install the noise filter.
*2 Follow the instructions below for the selection of the circuit breaker.
Breaker Rated Current Value > Power Capacity/ AC Input Voltage
(Refer to “Power Capacity and Heating Value” for Power Capacity.)
• The current might pass through the controller three times more of the rated current at the acceleration. Select one that
does not trip when the above current passes. When it trips, select the breaker with a rated current one rank above.
• Select the breaker that does not trip with the rush current. (Refer to the operating characteristic curve described in the
manufacturer
′s catalog.)
• For the rated breaking current, select the current value which can break the current even when a short circuit occurs.
Rated Breaking Current > Short-circuit Current = Primary Power Supply Capacity/Power Voltage
Select the breaking current value for the circuit breaker leaving some margin.
*3 When the leakage breaker is to be installed, it is required to select it with the purpose clarified such as protection from
fire or human body protection.
For the leakage breaker, measure the leakage current at the location where the leakage breaker is installed, and select it.
Use the “applicable to higher harmonics type” leakage breaker.
*4 For the CE marked type, the attachment of the clamp filter for each model shown in the figure, and the connection to
the surge protector, are required.
In addition, for all the cables to be connected to SSEL, arrange them with a length less than 30m.
