10 AC LInE fUSInG
This drive does not contain AC line fuses. Most electrical codes require that each ungrounded con-
ductor contain circuit protection.
Do not fuse neutral or ground connections.
It is recommended
to install a fuse (Littelfuse 326, Buss ABC, or equivalent) or a circuit breaker in series with each
ungrounded conductor.
Do not fuse motor leads.
For the recommended fuse size, see Table 1, on
page 14. Wire the drive in accordance with the National Electrical Code requirements and other
local codes that may apply to the application.
11 DRIVE OPERATIOn
11.1 Start-Up Procedure –
After the drive has been properly setup (jumpers and trimpots set to
the desired positions) and wiring completed, the startup procedure can begin. If the AC power
has been properly brought to the drive, the power (PWR) LED will be illuminated green. The
status (ST) LED will indicate drive status, as described in Section 11.2. To remove and install
the Finger-Safe Cover, see Section 5, on page 22.
11.2 fault Recovery –
The drive monitors four faults (Undervoltage, Overvoltage, Short Circuit at
the motor (phase-to-phase), I
2
t). Table 3, describes how the drive will automatically start (fac-
tory setting) after the fault has cleared.
Application note: In Manual Start Mode, the drive must be manually reset for any fault.
Use the Manual Start Switch, as described in Section 9.6, on page 33. Also see Section
12.2, on page 38.
