MX-Overvoltage-Protection-Box-RJ45/LSA
31.684-008_EN_04/2017
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.
