fixed field wiring.
For terminal with AC power cable/IEC connector

follow these steps:
1.
Turn off the power to the terminal at the source.
2. Find the fuse on the back of the terminal (Figure 2 on page 11).
3.
Use a flat-blade screwdriver to turn the fuse holder counter-clockwise until
the fuse holder pops out.
4. Remove the fuse from the holder.
5.
Replace the fuse with another fuse of the same type. For fuse specifications,
see page 58.
6. Re-insert the holder and use the screwdriver to turn it clockwise until it
locks.
