Controller Installation

EMP400 Series DIN Rail Mounting Use DIN rails with a width of 1.38 in. (35 mm). Use end plates to secure the controller. DIN rails and end plates are not provided with the unit.

EMP400 Series, SC8800/SC8800E Screw Mounting To fasten the unit with screws, use the two screw holes at the top and bottom. The mounting holes should be machined for either M3 or M4 size screws. Use washers to secure the controller.

SG8030J DIN Rail Mounting using Flush Connection Socket Mount the flush connection socket to the DIN rail. (The DIN lever should face down.) Insert the controller terminals firmly into the flush connection socket. Engage the fastening hooks of the flush connection socket on the controller to secure the assembly. Mount the controller only after connecting all required leads to the terminals of the flush connection socket.

SG8030J Panel Mounting using Rear Connection Socket Insert the controller into the mounting cutout from the front. Insert the flush mount adapter from the rear and push it in. Fasten the adapter with the fitting screws (2 locations). Insert the controller terminals firmly into the rear connection socket.

Installation Conditions

• Indoors, ambient temperature 32°F to 122°F (0°C to +50°C) [32°F to 104°F (0°C to +40°C) for SG8030J] (Nonfreezing)
  • If the ambient temperature exceeds 122°F (+50°C) [104°F (+40°C) for SG8030J], use a fan to provide forced cooling. Otherwise, the internal heat buildup may lead to damage.
  • When installing the controller in an enclosed space such as a control box, or somewhere close to a heat-radiating object, ventilation holes should be used to prevent the controller from overheating.
• Ambient humidity 85% maximum (Noncondensing)
• Not exposed to corrosive gas or dust
  Take care that pieces of conductive material (filings, pins, pieces of wire, etc.) do not enter the controllers. Otherwise circuit damage may occur.
• Not exposed to water or oil
  Exposure to liquids can lead to corrosion or short-circuits.
• Not exposed to direct sunlight
• Not in the vicinity of noise sources
  In situations where controllers are located close to an electrical noise source such as high frequency welding machines or large electromagnetic switches, take steps to prevent noise interference, either by inserting noise filters, using shielded wires or connecting the controller to a separate circuit.
• Not in the vicinity of vibration sources
  When the controller is to be installed in a location where a source of vibration will cause the controller to vibrate as well, install a shock absorber.
• Do not over tighten screws
  When fastening the unit with screws, use appropriate tightening torque. Take care not to damage the case by over tightening.
