1.2 AC Line Fusing – It is recommended that a fuse(s) or circuit breaker be installed in the AC Line.
Fuse each conductor that is not at ground potential. For the recommended fuse size, see Table 4
on page 14. Also see Section 11 on page 28.
1.3 Ground Connection – Connect the ground wire (earth) to the ground screw, as shown in Figures
10 -12 on page 20. See Section 5.2 on page 20.
1.4 Motor Connection – Wire the motor to Terminal Block TB1 Terminals U, V, W, as shown in
Figures 10 -12 on page 20. (Special reactors may be required for cable lengths over 100 ft. (30 m) –
consult our Sales Department.) See Section 5.3 on page 21.
1.5 60 Hz And 50 Hz Motor Operation – The drive is factory set for 60 Hz 3-phase motor operation
(Jumper J5 set to the "60Hz" position). For 50 Hz motor operation, set Jumper J5 to the "50Hz"
position. See Section 6.4 on page 24.
1.6 Start/Stop Switch – The drive is supplied with a prewired Start/Stop Switch to electronically
"start" and "stop" the drive, as described in Section 5.5 on page 21. This switch must be used to
"start" the drive each time the AC Line is applied to the drive or to "restart" the drive. Also see
Section 6.8 on page 25.
1.7 Jumper Settings – All jumpers have been factory set for most applications. However, some
jumpers may need to be set in order to tailor the drive for a specific application. See section 6
on pages 23 – 26.
IMPORTANT: In order to ensure that the motor is properly protected with the I
Protection feature, it is required that Jumper J2 is set to the corresponding position for the motor
horsepower being used, as shown in Figure 22 on page 24.
1.8 Trimpot Settings – All trimpots have been factory set for most applications. Some applications re-
quire adjustment of the trimpots in order to tailor the drive for a specific requirement. See Section
13 on pages 29 – 32.
1.9 Diagnostic LEDs – After power has been applied, observe the LEDs to verify proper drive
operation, as described in Section 12 on pages 28 and 29.
