Equipment damage from electrical discharge
● Electro static discharge can inflict irreparable damage to electronics! Before installing cabling,
always first discharge yourself by touching a well-grounded object.
● Always install the unit according to the EMC guidelines (Electro Magnetic Compatibility) and
according to local requirements (e.g. in Canada, the Canadian Electrical Code, C22.1, Part 1
and in USA, the National Electrical Code, NFPA 70 and ANSI/ISA-RP 12).
Risk of short circuits and overheating
● Use only an effective screened cable for the input signal and ground it to terminal S1 (GND)
AND to the housing, or at the sensor itself, whichever is appropriate to the application. Be
careful not to create ground loops.
● Without a thermal separator, the process temperature shall not exceed the specified maximum
ambient temperature.
● If, due to internal dissipation, the housing temperature exceeds 70 °C / 158 °F, use suitable
cable and gland to withstand high temperatures.
