° If two or more drives need to be installed in the same device or control panel, they should be ar-
ranged horizontally to minimize the influence of heat between them. If two or more drives must be
installed vertically, place a plate between them to prevent the upper drive from being affected by
heat from the lower drive.
Figure 2-2-2 How to install two or more drives
! CAUTION
1. Do not allow foreign matter such as lint, paper dust, small chips of
wood or metal, and dust to enter the drive or adhere to the heat sink.
Otherwise, a disaster such as burning could occur.
2-3 Connection
Remove the surface cover to connect the terminal blocks. Correctly connect them according to the fol-
lowing procedures.
2-3-1 Basic connection
¬ Always connect the power to the main power supply input terminal of the drive. If it is connected to
another terminal, the drive will be damaged (see Figure 2-3-1).
- Always ground the ground terminal to prevent disasters such as fire and electric shock and to mini-
mize noise.
® Use a reliable crimp terminal for connection between a terminal and wire.
¯ After terminating the connection (wiring), check the following items:
a. Whether the connection is correct
b. Whether all necessary connections have been made
c. Whether there is a short-circuit or ground fault between terminals and wires
° Connection modification after power-on
The smoothing capacitor in the direct current part of the main circuit cannot be discharged quickly
after the power is turned off. Use a multimeter to check that the voltage of the direct current (DC) is
reduced to the safety range (25V dc or less) after the charge lamp goes off to avoid danger. Check
that the voltage is zero before short-circuiting a circuit because the residual voltage (electric charge)
may cause sparks.
! WARNING
1. Always connect the ground wire,
otherwise electric shock and fire could occur.
2. Ensure that a licensed specialist performs the wiring work.
3. Check before starting the wiring that the power is off,
otherwise electric shock could occur.
