This procedure covers the factory-installed fuses inside the TrueBlend SB-4 electrical
control panel. If you have installed an electrical disconnect or emergency stop switch,
additional fuses and/or breakers may have been used elsewhere in the main power cir-
cuit.
Located inside the TrueBlend SB-4 electrical control panel are fuses for the AC line,
FU1, and the power supply output side, FU2 and FU3.
To replace a blown fuse:
1
Disconnect and lockout the main power.
2
Open the electrical enclosure door.
Turn the screws on the front panel counter-
clockwise to open.
3
Replace the fuse.
The fuses are located inside the control cabinet and are labeled
and identified on the subpanel and the electrical print.
4
Close the electrical enclosure and restart the unit.
