J7 Simplified Startup Procedure
This procedure is a simplified step by step guide to installing, programming, and using the
J7
d rive. It highlights several common installation configurations. Detailed information on
all features of this drive can be found in the Technical Manual .
INSTALLATION
1. Be certain your input voltage source, motor and drive nameplates are all marked either
230V or 460V. Other voltages can be used, but require additional programming, see
technical manual. CAUTION: Verify that the input voltage matches th
e Drive’s
nameplate BEFORE applying power or severe damage will result.
2. Mount D rive on a vertical surface with adequate space for air circulation (4.7” above and
below, 1.2” on each side).
3. Remove front cover using the screw in the lower left corner, then connect power and
ground wires as shown.
CAUTION: BE CERTAIN YOU CONNECT INPUT POWER TO TERMINALS L1, L2,
AND L3 ONLY, OR SERIOUS DAMAGE WILL RESULT. CONNECT MOTOR TO
TERMINALS T1, T2, AND T3 ONLY.
4. Replace cover and apply input power –
digital operator shows “0.0”; The FREF
LED is on and the RUN LED is flashing.
Press the DSPL key until the LO/RE LED
is on. Press the UP ARROW button until
the display shows “Lo”, then press the
DSPL button until the FREF LED is on.
Rotate the potentiometer on the front of
the digital operator until the display shows
“6.0”. Press the RUN button and note the
direction of motor rotation. If rotation is
incorrect, remove power, wait for the
display lights to go out, then switch wires
between terminals T1 and T2. Replace
the front cover and apply input power.
