  • Page 4 SAFETY PRECAUTIONS Be sure to read this manual and all other attached documents carefully before installing, operating inspecting or conducting maintenance on this unit. Always use this unit properly. Be sure to carefully read the information about the device, the safety information and precautions before using this unit.
  • Page 5 REQUIREMENT An electric shock may lead to a deatch or burn. Noise may cause the system to malfunction. Ground the line ground (LG), frame ground (FG), and shield (SHD) terminals, as described below. • Electrically insulate the mount base from the cubicle. To assure this, do not remove the insulating sheet from the mount base.
  • Page 6 CAUTION High operating temperatures may cause the unit to fail. Further, electromagnetic interference from adjacent equipment may cause the unit to malfunction. Allow for clearances of specified dimensions between the enclosure and the programmable controllers and between the programmable controllers to assure heat dissipation and alleviate interference. During test running after mounting, measure the temperature around the programmable controllers in the enclosure to make sure that they do no exceed specified tolerances.

  • Page 16: Cpu Mount Base

    1 BEFORE USE 1.1 CPU Mount Base A CPU mount base is needed to use this module. CPU mount bases are available in three types: • Two-slot mount base (Type: HSC-1020) • Four-slot mount base (Type: HSC-1040) • Eight-slot mount base (Type: HSC-1080) As an example, the eight-slot mount base Figure 1-1 Mount Base houses up to eight optional modules.
  • Page 17 1 BEFORE USE PS slot: Mount one of the following power supply modules: • LQV000 • LQV100 • LQV020 CPU slot: Mount one of the CPU modules: • LQP000 • LQP010 • LQP011 • LQP120 Slots 0 thru 7: Mount optional modules, such as the LQE050, and I/O modules. Insert optional modules into slots, starting from slot 0, with no intervening vacant slots.

  • Page 18: Ground Wiring

    1 BEFORE USE 1.3 Ground Wiring Carry out ground wiring as shown in Figure 1-3 by following these steps: ① Connect the FG terminals of the power supply module, CPU module and optional modules by crossover wiring to the mount base’s grounding seat, a hexagon nut fitted to the mount base (with a wire diameter of 2.0 mm or more).
  • Page 19 1 BEFORE USE DANGER Turn off the power before making connections to the terminal block. Wiring with the power turned on may incur electrical shock hazards. REQUIREMENT An electric shock may lead to a deatch or burn. Noise may cause the system to malfunction.
