Quick Install

MX-Overvoltage-Protection-Box

Standard Delivery

MX-Overvoltage-Protection-Box

• Protects MOBOTIX cameras against surges of up to 4 kV on 

the PoE network cabling

• For patch cable to patch cable or patch cable to installation 

cable (MX-Overvoltage-Protection-Box-LSA)

• Complete set including mounting supplies
• Ideal for replacing MX-Patch-Box

Surge Protection for 

MOBOTIX IP Cameras

Weatherproof network connector (IP66) with surge protection 

of up to 4 kV for MOBOTIX IP cameras.

MOBOTIX patch cable 

max. 50 cm/20 in

This variant allows using a network installation cable to the PoE switch. The wires are inserted into the LSA 
terminal in the center, while the MOBOTIX patch cable connects to the camera. The ground wire is attached at 
the left (only qualified electricians are allowed to do this!).

The patch cables with integrated sealing rings (available from MOBOTIX in different lengths) are simply inserted into 
the RJ45 connectors and fastened using the bayonet catch (1 patch cable to end device, 1 patch cable to PoE switch/
injector). The ground wire is attached at the center (only qualified electricians are allowed to do this!).

Surge Protection for MOBOTIX IP Cameras

Surges are voltages that exceed the allowed voltage range for MOBOTIX IP cameras. The max. voltage for PoE, for example, is 57 V. 
Surges do not necessarily result in irreparable damages to MOBOTIX IP cameras. Only if the voltage is exceeded by a multiple of 
the allowed value, or if the surge is present for a longer period of time or even permanently, damages are unavoidable.

Examples for Causes of Surges

•  Direct lightning strike into the installation itself or the network cable
•  Lightning strike into the power supply or the ground in the vicinity (within a radius of 100 km/62 mi)
•  Switching of high loads, especially if network and power lines run side-by-side

Surge Protection

In order to reduce the danger of damages resulting from surges, a specialist should establish a surge protection concept and 
implement such a system. Such a system consists of several surge protection zones, where each zone contains specific and gener-
ally applicable countermeasures. These range from lightning capture devices and double-shielded network cables to fine-level 
surge protection for end devices. When selecting the countermeasures, not only technical, but also economical aspects need to 
be considered in order to find the proper balance between protection and costs.
The 

MX-Overvoltage-Protection-Box-RJ45 and MX-Overvoltage-Protection-Box-LSA can be used in most of the protection zones 

and provide a cost-efficient protection against surges. It is generally recommended to install an MX-Overvoltage-Protection-Box if 
MOBOTIX cameras are installed outside of buildings. These devices protect MOBOTIX cameras against short surges of up to 4 kV.

Caution

•  The cable between the MX-Overvoltage-Protection-Box and the MOBOTIX camera must 

not be longer than 50 cm/20 in.

•  An MX-Overvoltage-Protection-Box protects against surges of up to 4 kV on a network 

patch or installation cable, but not against direct lightning strikes.

Important Notes

•  The cable from the MOBOTIX device to this product must not 

be longer than 50 cm/19.7 in.

•  When using an installation cable, pay attention to the correct 

twisting and shielding of the cable.

•  Position of holes in combination with VarioFlex wall mount: 

see drilling template below.

•  All unused ports must be closed with the supplied rubber seals.
•  Maximum torque for all box cover screws: 0.4 Nm.
•  The ground wire may only be connected by qualified electricians.

•  This product must not be used in locations exposed to the 

dangers of explosion.

•  It is only allowed to connect one MOBOTIX device to this 

product.

•  Make sure that you are installing this product on a solid surface.
•  Make sure that you are installing this product with the con-

nectors pointing downwards.

•  If the surcharge is higher than 4 kV, internal parts may get 

destroyed  in  order  to  prevent  damage  to  the  attached 

device.  In  this  case,  you  will  have  to  exchange  the 

MX-Overvoltage-Protection-Box at your own cost; any war-

ranty is excluded.
