Fuse Replacement—Model 494.33 DI/O Power Supply
The Model 494.33 DI/O Power Supply includes output fuses and a resettable
circuit breaker that is built into the power switch.
Fuse replacement 1. If required, shut down system hydraulics.
2. Switch the Power switch on the front of the power supply to the off
position.
3. Check the fuses.
Replace any blown fuses with the exact replacement value listed below:
Fuse FI and F2 (Output Pwr)—7 A, 250 V, Slo-Blo
Fuse F3 (Input Pwr)—7 A, 250 V, Slo-Blo
When used in an electrical circuit, the voltage and current (amperage)
ratings of a fuse are selected to limit the capacity of the circuit and to
provide protection of the devices (equipment) in the circuit.
Using fuses with ratings that are different from the ones specified can
result in fire or electrical damage to the equipment. Fire can also result
in injury or death to personnel.
Before replacing a fuse, troubleshoot and correct the cause. Look for
damaged conductors (for example, wires, switches, relays, terminals, and so
on) and faulty equipment. Replace a fuse only with one that has the same
ratings.
4. Determine the cause of the blown fuse and fix the problem.
5. If required, check the controller input/output status to make sure that
they are set to a safe state.
6. Switch the Power switch on the front of the power supply to the on
position.
