2.3.1 Connecting the power supply
IDEC SmartRelays (FL1E-*12RCC, FL1B-M08C2R2) are
suitable for nominal line voltages of 100 V AC/DC and 240 V
AC/DC. IDEC SmartRelays (FL1E-*12RCA, FL1B-
M08D2R2) are suitable for a supply voltage of 24 V AC/DC.
IDEC SmartRelays (FL1E-H12SND, FL1B-M08B1S2) are
suitable for a supply voltage of 24 V DC. IDEC SmartRelays
(FL1E-*12RCE, FL1B-M08B2R2) are suitable for a supply
voltage of 12 V AC/DC or 24 V AC/DC. 
Note the information on connection in the product
information document shipped with your device and the
technical specifications in Appendix A relating to permissible
voltage tolerances, line frequency and current consumption.
The Text Display must be supplied with a voltage of 12 V DC
or 24 V AC/DC.
Note
A power failure might cause an additional edge triggering signal at
the special functions.
The stored data will be from the last uninterrupted cycle.

Protection with safety fuse if
required (recommended) for:
FL1E-H12RCE: 0.8 A
FL1E-H12SND: 2.0 A
To suppress surge voltages,
install varistors (MOV) with an
operating voltage at least 20 %
above the rated voltage.
Note
IDEC SmartRelay is a double-insulated switchgear. You do not
need to connect an equipment grounding conductor.
