If SECU-DATA 42xx is not operated in an explosive area (Ex-zone 1) the
units can be supplied from a standard, not intrinsically safe 24 V DC power
supply, the barrier SECU-BAR 125 is not required.
Receiver site: The barrier SECU-BAR 125 for the SECU-DATA 420C/421C
is required for Ex-zone 1 only. Outside of hazardous areas a SECU-DATA
1420C/141C without a barrier can be used.
Hint: Please, order in addition to the SECU-DATA 42xx set one or two bar-
riers SECU-DATA 125 (order no.: SB125) according to the Ex-protection
requirements.
