[Startup and Maintenance Precautions]
CAUTION
● Do not touch the integrated circuits on the circuit board of an extended SRAM cassette or a battery-
less option cassette. Doing so may cause malfunction or failure of the module.
● Do not drop or apply shock to the battery to be installed in the module. Doing so may damage the
battery, causing the battery fluid to leak inside the battery. If the battery is dropped or any shock is
applied to it, dispose of it without using.
● Startup and maintenance of a control panel must be performed by qualified maintenance personnel
with knowledge of protection against electric shock. Lock the control panel so that only qualified
maintenance personnel can operate it.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Wearing a grounded antistatic wrist strap is recommended.
Failure to discharge the static electricity may cause the module to fail or malfunction.
● After unpacking, eliminate static electricity from the module to prevent electrostatic discharge from
affecting the module. If an electrostatically charged module comes in contact with a grounded metal
object, a sudden electrostatic discharge of the module may cause failure. For details on how to
eliminate static electricity from the module, refer to the following.
Antistatic Precautions Before Using MELSEC iQ-R Series Products (FA-A-0368)
● Use a clean and dry cloth to wipe off dirt on the module.
● Before testing the operation, set a low speed value for the speed limit parameter so that the operation
can be stopped immediately upon occurrence of a hazardous condition.
● Confirm and adjust the program and each parameter before operation. Unpredictable movements
may occur depending on the machine.
● When using the absolute position system function, on starting up, and when the module or absolute
position motor has been replaced, always perform a home position return.
● Before starting the operation, confirm the brake function.
● Do not perform a megger test (insulation resistance measurement) during inspection.
● After maintenance and inspections are completed, confirm that the position detection of the absolute
position detection function is correct.
● Lock the control panel and prevent access to those who are not certified to handle or install electric
equipment.
