System Grounding Information
The detachable three-wire power cord is used for connection to both the power source and
protective ground. The protective ground conductor (colored green/yellow) in the power
cord is internally connected to the exposed metal parts of the MV Controller. To ensure
electrical-shock protection, the protective ground conductor must be connected to a
properly grounded power source.
WARNING:
Ensure that a proper protective ground connection exists
before turning on the power.
3.5 Fuse Information (MV-5 and MV-10)
The two fuses (F1 and F2) at the power entry module on the front panel are for the
incoming AC power lines. See the table below for ratings.
WARNING:
Only skilled or instructed personnel should attempt to
change any fuses. Always replace blown fuses with new fuses of the same
type and rating.
Procedure to Remove Fuse Holder
1. Turn off AC power to the controller and disconnect the power cord from the AC
power source.
2. Remove the AC power cord from the socket on the power entry module.
3. To remove the fuse holder, insert a small flat-blade screwdriver into the slot
between the fuse holder and the power cord socket, then lift up to release the fuse
holder; see Figure 3-4. Spare fuses are stored in the sliding compartments.
4. To reinstall the fuse holder, insert it in place, then press down firmly until the
entire holder snaps into position.
