DC Power Requirements
Connection to the product should be made in isolated secondary circuits (SELV). The following voltage
specification is applied at the power connector of the drive.
Damage to the file electronics may result if the
power supply cable is connected or disconnected while power is being applied to the file
(Hot plug/unplug is
not allowed)
.
There is no special power on/off sequencing required.
