  • Page 2 Thank you very much for purchasing our Digital Indicator F372A. For good performance, and proper and safe use of the F372A, be sure to read this operation manual and properly understand the contents of it before use. Also, carefully keep this operation manual so that it can be referred to at any time.
  • Page 3 ● For the entire system to function safely when the F372A becomes faulty or malfunctions, provide a safety circuit outside the F372A. ● Before using the F372A as described below, make sure to consult with our sales personnel. - Use in environments not described in the operation manual.
  • Page 4 ● In the case of smoke, an abnormal smell or strange sound, immediately turn off the power, and disconnect the power cable. ● As for the batteries used in F372A, do not at any time dismantle the batteries, change the batteries shape by subjecting it to pressure or throw the batteries into fires as these may cause the batteries to explode, catch fire or leak.
  • Page 5 ● For turning on/off the power, be sure to keep intervals of 5 seconds or more. ● After power-on, make sure to warm up the F372A for at least 30 minutes or more before use. ● If the F372A is not used by the specified method, its protective performance may be impaired.
  • Page 6 When installing, attention should be given to the following. 1. Since the F372A is defined as open type (built-in equipment), be sure to use it as installed and fixed to a panel, etc.
