    1.16 Storage During storage, a temperature range between +50°F (10°C) and +95°F (35 °C) is recommended in order to prevent premature aging of components, particularly the electrolytic capacitors. For longer storage periods, it is recommended that voltage be applied to the device power supply for one or two days every other year, in order to regenerate the electrolytic capacitors.
  • Page 36 WARNING! For field wiring and installation, all national and local codes must be adhered to. During electrical installation, all rules and regulations for power systems must be observed. • If current transformers are used, the secondary connections of the current transformers must be short- circuited before the current leads to the device are interrupted.
  • Page 37: Connection Examples
