Interventions in the hardware and software of our products, unless de- scribed otherwise in this manual, are reserved to specialized Bosch person- nel. Tampering with the hardware or software, ignoring warning signs attached to the components, or non-compliance with the warning notes given in this manual can result in serious bodily injury or property damage.

  • Page 12: Installation And Assembly

    Safety instructions Installation and assembly DANGER Non-workmanlike installation or mounting may lead to personal in- jury or damage to property. Therefore, it is essential that you take the technical data (environ- mental conditions) into account for installation or mounting. Installation or mounting must be carried out by skilled personnel only.
  • Page 13 Safety instructions DANGEROUS ELECTRICAL VOLTAGE Before the modules are installed, the respective mounting station must be safely isolated from supply and properly safeguarded to pre- vent unintentional or unauthorized reclosing. CAUTION Short circuits! When cut-outs are drilled or sawed in switchgear cubicles, metal burr may get into modules already installed there.
  • Page 14 Safety instructions CAUTION Damage to property through inappropriate or insufficient cooling of the thyristor power units! Water-cooled thyristor power units may only be operated when the cooling water circuit is active! Condensation on water-carrying com- ponents must be prevented. Damage to property through insufficient water quality in the cooling water circuit! Deposits in the cooling system may reduce the water flow, thus im- pairing the performance of the cooling system with time.

  • Page 15: Electrical Connection

    Safety instructions Electrical connection DANGEROUS ELECTRICAL VOLTAGE The mains voltage is associated with many dangers! Possible consequences of improper handling include death or most severe injuries (personal injuries) and damage to property. For this reason, the electrical connection must always be made by an electri- cal expert in compliance with the valid safety regulations, the mains voltage and the maximum current consumption of the individual units of the equipment.
  • Page 16 Safety instructions 1-10 DANGEROUS ELECTRICAL VOLTAGE Danger of life through insufficient protective conductor system! The thyristor power units must be connected to the protective earth- ing (PE) circuit of the system. Please ensure that the cross-sectional area of cables used for protective conductor wiring is sufficiently large.
  • Page 17 Safety instructions 1-11 PE connection : Connect to a central earth point. Make sure that cable cross-sectional areas are sufficiently large! All conductor cross-sections must be large enough for the loads to be con- nected. U1 connection : Connect to L1 system phase. V1 connection : Connect to L2 system phase.

  • Page 18: Ensuring Emc Of The Completely Assembled System

    Safety instructions 1-12 Ensuring EMC of the completely assembled system Note: The completely assembled system with the welding transformer complies with prEN 50240, the EMC product standard for resistance welding systems, and EN 55011 (October 1997), EMC product family standard class A, group 2, rated current > 100 A. D Only for industrial applications.

  • Page 19: Operation Of The Thyristor Power Units

    All users, line designers, welding machine manufacturers and weld- ing gun producers are obliged to connect the output signal of the Bosch weld timer which initiates the electrode movement so that the applicable safety regulations are complied with. The risk of bruises can be considerably reduced by means of, e.g., two-handed start, guard rails, light barriers etc.
