FP-RLY-420 10 www.natinst.com
•Do not share the external supply voltages (V and C on the
terminal base) with other devices (including other FieldPoint
devices) unless those devices are also isolated from human
contact.
• As with any hazardous voltage wiring, ensure that all wiring
and connections meet with applicable electrical codes or
common sense practices. Mount terminal bases in an area,
position, or cabinet that prevents accidental or unauthorized
access to wiring with hazardous voltages.
• The isolation of the FP-RLY-420 is certified as double
insulated for normal operating voltages of 250 Vrms. Do not
use the FP-RLY-420 as the sole isolating barrier between
human contact and working voltages of more than 250 Vrms.
