Notes for Operation

Mounting Clamp

OKNG

・ For confirmation about the environmental specification and the operating environment forinstallation, see the instruction manual of HG series.
Procedure 6. Fasten the mounting clamp with the screw to a specified torque of 0.6 N･mpushing the mounting clamp as shown in the following figure.
After fastening the mounting clamp, make sure that the mounting clamp is notloose and not having a gap.

・ Regularly check the mounting clamp is tightened sufficiently. If the mounting clamp is loose,tighten it to the recommended tightening torque.

・ Turn off the power supply when you set up the unit, connect cables or perform maintenanceand inspection.
・ Before connecting the expansion module, see the instruction manual of HG series. Incorrect
handling of the HG will result in falling, failure, electrical shock, fire hazard, or malfunction.
・ Do not deform the mounting clamp. If the mounting clamp is deformed, the expansion
module is not in the right position.
