  • Page 4 SAFETY PRECAUTIONS Before installation, operation, maintenance, and/or inspection of this product, be sure to read through carefully this manual and other related manuals. Do not use this product until you are familiar with all the information concerning this product, safety information, and precautions provided in those manuals.
  • Page 5 Do not install, wire, handle, modify, or use maintenance parts in any manner not described in this manual. Such a practice may result in breakdown of this equipment or peripherals, injury or even death. Hitachi will not be responsible for any accident or failure resulting from such mishandling.
  • Page 6 During work For each procedure, follow the given sequence of steps. Use the special tools and instruments, specified for the work in the manual or commercially available tools and instruments which fit the purpose. Use measurement instruments and powered tools which are properly calibrated or periodically inspected.
  • Page 7 Prevention of electric shocks Before starting work, make sure that, unless otherwise specifically instructed, there is no potential electric hazard in the maintenance area such as insufficient grounding or a wet floor. Before starting work, note where the emergency power-off switches are located and make sure you know how to operate them.
  • Page 8 Procedures in an emergency For electric shock Do not panic. Do not become another victim through contact with the injured person. First, shut off the electric current passing through the victim. Use the emergency power-off switch, if there is one, or, otherwise, a normal power- off switch.
  • Page 9 Hazard Warning Statements The following are the hazard warning statements contained in this manual. WARNING Statements (chapter 3, page 3-5) WARNING Switch off the power supply before making connections to the terminal block. Making connections with the power supply being switched on may incur electrical shock hazards.

    Figure 6-2. At measurement, switch on the SD.LINK module with the module number of the adjoining SD.LINK module set to E or F. Carry out measurement with regard to both the primary and secondary rings. Connect the optical fiber cables and the optical power meter by way of a compatible connector adapter.

    Clean the optical module receptacle and optical connectors after measurement. Because the SD.LINK module (LQE530) uses a Type SC (or 2SC) optical connector, the optical power meter must support Type SC (or 2SC) accordingly. Use a Type SC (or 2SC) connector adapter (included with the optical power meter or sold separately).

    With the S10mini, one of the messages listed below is displayed in the CPU module indicator when a certain event or error occurs in the SD.LINK module. The S10V collects error information, but does not display errors on the LPU module. Error information collected can be referenced from Error Log on S10V Basic System.
