7.
Connect the communication cables to the terminal block as shown in Figure 9 .
When attaching the CN1 connector plug on the terminal block to the socket, make
sure the screws on the left and right sides of the plug are tightened with a tightening
torque of 0.5 to 0.6 (N･m) or 4.4 to 5.43 (inch-lbs). Take particular caution to ensure
that each wire is properly connected and wire insulation is not accidentally pinched
into electrical terminals. Trim any frayed wires.
WARNING! Fire Hazard. Tighten all terminal screws according to the specified tightening torque. Loose
electrical connections could result in death or serious injury by fire due to overheating electrical connections.
Tightening screws beyond the specified tightening torque may result in erroneous operation, damage to the
terminal block, or cause a fire.
NOTICE: Heat shrink tubing or electrical tape may be required to ensure that cable shielding does not come
into contact with other wiring. Insufficient insulation may cause a short circuit that can damage the option or
the drive.
