2) Table 5.2 shows the maximum heat generated by each Module of the GL120 and GL130.
Use this information to calculate control panel cooling capacity.
5.1.3 Preventing Electrical Noise
This section describes how to prevent electrical noise from being generated in the GL120 or
GL130. Always observe the items described in this section to improve the noise immunity of
the GL120 or GL130.
Note (1) Avoid installing the GL120 or GL130 components in the same control panel as a high-
voltage or high-amperage circuits. A high-voltage or high-amperage circuit is a circuit
in which the voltage exceeds 600 VAC (750 VDC) or the amperage exceeds 800 A.
(2) If the GL120 or GL130 components are to be installed in the same control panel as a
low-voltage main circuit, keep the GL120 or GL130 components and their cables as far
from the low-voltage main circuit devices and cables as possible. The recommended
distance between them is at least 200 mm. A low-voltage main circuit is a circuit in
which the voltage is 600 VAC (750 VDC) or less and the amperage exceeds 20 A.
(3) Do not bundle the GL120 or GL130 cables with control circuit cables. A control circuit is
a circuit in which the voltage is 600 VAC (750 VDC) or less and the amperage is 20 A or
less.
(4) Note the following when installing the Mounting Base on a device mounting steel plate:
