Crimp Ferrules
Attach an insulated sleeve when you use crimp ferrules. Refer to the table for the recommended external
dimensions and model numbers of the crimp ferrules.
Use the CRIMPFOX 6, a crimping tool made by PHOENIX CONTACT.

Wiring the Control Circuit Terminal
WARNING
Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. If you
touch the internal components of an energized drive, it can cause serious injury or death.
NOTICE
Do not let wire shields touch other signal lines or equipment. Insulate the wire shields with electrical tape or
shrink tubing. If you do not insulate the wire shields, it can cause a short circuit and damage the drive.
Note:
•
Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/T3, -, +1, +2) and other
high-power wiring. If control circuit wiring is adjacent to main circuit wiring, it can cause incorrect operation of the drive and
equipment from electrical interference.
•
Isolate wiring for contact output terminals MA, MB, MC and M1-M6 from other control circuit wiring. If contact output terminal
wiring is adjacent to other control circuit wiring, it can cause incorrect operation of the drive and equipment from electrical
interference.
•
Use a Class 2 power supply to connect external power to the control terminals. If the power supply for peripheral devices is incorrect, it
can cause a decrease in drive performance.
•
Connect the shield of shielded cable to the applicable ground terminal. Incorrect equipment grounding can cause drive or equipment
malfunction from electrical interference.
Correctly ground the drive terminals and complete main circuit wiring before you wire the control circuit.
Remove the keypad and front cover.
1.
Push in on the tabs on the both sides of the LED status ring board to release the board from the bracket.
Pull the board forward to remove it.
NOTICE
When you remove the LED Status Board from the drive bracket, make sure that you temporarily
install it in the holding position provided on the drive. If you cause damage to the LED status ring board, the LEDs will
not function correctly.
