* Outputs must be protected by a 250 V quick-acting
fuse (recommended fuses: Wickman 194-1100 1.1
A and Littelfuse 0217-800 V 800 mA).
When mounted in a hazardous area in accordance
with the National Electric Code (NEC), use only a
suitable tool to remove the fuse if the module is not
located in a potentially explosive atmosphere.
