5.1.1 Structure of Control Panel
1) Yaskawa recommends the following control panel structure:
a) Dustproof or dust resistant structure
b) Enclosed steel housing and self-standing structure (or wall-mounted)
2) Table 5.1 shows the approximate mass of each Module and Mounting Base for the
GL120 and GL130. Use this information to calculate the mechanical strength of the con-
trol panel.
5.1.2 Cooling the Control Panel
Note
If the temperature inside the control panel is likely to exceed the maximum allowable ambient
temperature of each device to be mounted in the control panel, install a cooling fan on the
ceiling of the control panel or use some other cooling method. If a cooling fan is to be used,
install the fan so that it discharges air from inside the control panel.
1) The allowable ambient temperature range of each GL120/GL130 component is shown
below.
a) Allowable ambient temperature range: 0 to 60_C
(1) Power Supply Modules
(2) CPU Module
(3) Communications Modules
(4) I/O Modules
