Product Safety
UL, cUL, CE Note: When an IND131xx or IND331xx terminal is installed
into an area classified as Division 2 or zone 2/22, special AC wiring
requirements must be met. Refer to document 64068795 Division 2 and
Zone 2/22 Installation Guide. Provisions must be made to prevent
transient disturbances of more than 40% from the DC voltage supplied to
the IND131xx and IND331xx terminals.
