If waterproofing is desired, insert the waterproof packing. · When several Counters are installed, ensure that the ambient temperature will not exceed specifications. · The appropriate thickness of the panel is 1 to 5 mm. Note: A Compact Flush Mounting Bracket (Y92F-35) can also be used. Refer to Accessories for details. C-30 Self-powered Tachometer H7ER PCB-mounting Counters H7E@-N@P Counters Total counter Max. [. . . ] In such a case, it is suggested that the battery be replaced. PCB-mounting Counter Power Supply · Use the power supply within the applicable range indicated by the following waveform, while considering the ripple and voltage fluctuations of the circuit power source. Battery Replacement To prevent unwanted reset when replacing the battery, connect the new battery before disconnecting the old one. Otherwise, the voltage supplied to the counter circuit drops, causing the present count value to reset. When designing the circuit board, providing two extra terminals for battery connection will make the switch must simpler.
