Safety Information
The following section contains important safety information that you must follow when installing and
using the hardware.
Do not operate the hardware in a manner not specified in this document and in the user documentation.
Misuse of the hardware can result in a hazard. You can compromise the safety protection if the hardware
is damaged in any way. If the hardware is damaged, return it to National Instruments for repair.
Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely dry and
free from contaminants before returning it to service.
Do not substitute parts or modify the hardware except as described in this document. Use the hardware
only with the chassis, modules, accessories, and cables specified in the installation instructions or
specifications. You must have all covers and filler panels installed during operation of the hardware.
Do not operate the hardware in an explosive atmosphere or where there may be flammable gases or
fumes unless the hardware is UL (U.S.) or Ex (EU) Certified and marked for hazardous locations.
The hardware must be in a suitably rated IP 54 minimum enclosure for hazardous locations.
You must insulate signal connections for the maximum voltage for which the hardware is rated. Do not
exceed the maximum ratings for the hardware. Do not install wiring while the hardware is live with
electrical signals. Do not remove or add connector blocks when power is connected to the system. Avoid
contact between your body and the connector block signal when hot swapping hardware. Remove power
from signal lines before connecting them to or disconnecting them from the hardware.
Caution
The MID-7654/7652 does not provide overload protection for motor loads. Overload
protection
must
be provided externally by the system designer.
Caution
The MID-7654/7652 does not provide motor overtemperature sensing. External
temperature sensing
must
be provided externally by the system designer. Temperature sensing is
required for monitoring the motor temperature and disabling the drive.
Caution
When connecting or disconnecting signal lines to the MID-7654/7652 terminal block screw
terminals, make sure the lines are powered off. Potential differences between the lines and the
MID-7654/7652 ground create a shock hazard while you connect the lines.
