Io1+Io2≤10A
The ALQ07 power modules have no internal fuse. An external fuse must always be
employed! To meet international safety requirements, a 250 Volt rated fuse should
be used. If one of the input lines is connected to chassis ground, then the fuse must
be placed in the other input line.
Standard safety agency regulations require input fusing. Recommended fuse rating
for the ALQ07 Series is 2A.
