Environment temperature
Ambient temperature range: -5
℃
~ 55
℃
. When the ambient
temperature exceeds 55
℃
for a long time, it is best to choose a place
with good ventilation.
3.2 Installation occasion
◆
No corrosion, flammable and explosive gas and liquid places.
◆
Secure vibration-free areas.
◆
This product is designed for installation of environmental II
standard, pollution level 2 applications.
3.3 Installation method
The product shall be installed horizontally on the back panel of the
electric cabinet, and the distance between the product and the
equipment or cabinet wall above and below shall be no less than 20cm.
Installation in other directions is not conducive to the product itself heat,
and the product under the heat must not have equipment.
Install and fix with DIN slot
DIN slot of 35mm width can be used for installation under low vibration
environment. Open the DIN clasp at the bottom of the module and clip
the bottom of the module on the DIN guide rail; The rotating module is
close to the DIN guide rail and close the DIN clasp. Carefully check
whether the DIN clasp on the module is tightly fixed with the DIN guide
rail.
Install and fix with screws
In case of large vibration, screws must be used to fix the module. M3
can be used to fix the module on the back plate.
The overall size and mounting hole size of this module are shown in
the following. Figure.

For security (to prevent electric shock and fire accident), and reduce
the noise, the module of grounding terminal shall be in strict
accordance with the national electrical code requirements, grounding
resistance should be less than 100
Ω
. When more than one module
is grounded, single point grounding should be adopted. The ground
