Warning
The stepper motor connectors on this drive are energized when the unit is
powered on. Disconnect the MID-7604/7602 unit from the power outlet
before
connecting
wires to or disconnecting wires from the stepper connectors. Strip back the insulation of
the stepper wires to the stepper connectors no more than 7 mm.
Failure to do so could
result in electric shock leading to serious bodily injury or death.
Hot Surface
The bottom surface of the MID-7604/7602 can get very hot to the touch under
certain conditions. To avoid a burn hazard, refer to
in the
section of this guide for the appropriate current setting and
safety hazards.

Note
Items followed by an asterisk (*) are available on the MID-7604 only.
The two rocker switches on the MID-7604/7602 front panel are the
AC POWER and ENABLE. Figure 1 shows the location of these switches.
The AC POWER switch energizes the motor bus (+24 V) and the logic
(+5 V) power supplies. When switched on, the green power LED labeled
+5 V
illuminates. If this LED fails to illuminate, check the power cord and
main input fuse on the front panel.
The ENABLE switch enables or inhibits the stepper drivers. If the
ENABLE switch is in the inhibit position (off), the stepper drivers are
inhibited, and the yellow LEDs (the middle row of the LED status array)
and red LEDs (the top row of the LED status array) illuminate for all axes.

section of this guide for more information.
