Overview
Minimum clearance between the remote output devices and Safety PLCs:
No. | Description |
1Installation with spacers: the cable ducts’ height is greater than 40 mm / 1,57 in.; the vertical separation increases.
2The XPSMF2DO801 safety remote output device is mounted vertically.
| Note: Additional means are required to ensure that the remote output device does |
|
| not slide downwards while operating; any movement may cause strain on the |
|
| wiring. |
|
|
|
|
| On open mounting surfaces, observing the minimum clearance and ensuring |
|
| unobstructed air circulation will help maintain the optimum operating temperature. |

Heat | The increasing integration of electronic components into smaller parts results in |
|
| large amounts of heat dissipation on a small surface area. The amount of heat |
|
| produced depends on the device's external load. Depending on the design of the |
|
| device, installation, design location, air circulation, and environmental conditions |
|
| make a very significant impact on the product’s operating temperature. |
|
| It is important to comply with the approved environmental conditions when installing |
|
| the device. Reduced operating temperature extends the life of the device and |
|
| reliability of the installed components. |
|
| If the XPSMF2DO801 requires an additional enclosure to increase the ingress |
|
| protection, the enclosure case must be designed in such a way that the heat |
|
| generated inside it can dissipate from the surface of the enclosure. The type of |
|
| enclosure and location of installation selected must easily allow heat dissipation. If |
|
| possible, a fan should be used to ensure air circulation. |
|
|
|
|
| Note: An additional enclosure can be used to increase the ingress protection of the |
|
| XPSMF2DO801 safety remote output device. |
