Installation Section 4-1
Accessibility for Operation and Maintenance
• To ensure safe access for operation and maintenance, separate the
G9SP-series Controller as much as possible from high-voltage equipment
and moving machinery.
• The G9SP-series Controller will be easiest to install and operate if it is
mounted at a height of 1.0 to 1.6 m above the floor.
!Caution Do not touch the power supply or the area around the I/O terminals while
power is being supplied or immediately after power has been turned OFF.
Doing so may result in burns.
Precautions for Correct Use
After the power supply has been turned OFF, wait until the G9SP-series Con-
troller has sufficiently cooled before touching it.
Improving Noise Resistance
Leave space between the G9SP-series Controller and control panel or other
devices to allow adequate dissipation of heat generated by the power supply.
• Do not mount the G9SP-series Controller in a control panel containing
high-voltage equipment.
• Install the G9SP-series Controller at least 200 mm (6.5 feet) from power
lines.
• Ground the mounting plate between the G9SP-series Controller and the
mounting surface.
Temperature Control
The ambient operating temperature around the G9SP-series Controller must
be between 0 and 55°C. Observe the following precautions.
• Provide enough space for good air flow.
• Do not install the G9SP-series Controller above equipment that generates
a large amount of heat such as heaters, transformers, or high-capacity
resistors.
• If the ambient temperature exceeds 55°C, install a cooling fan or air con-
ditioner.
