Ground wire
1.5 to 2.5 mm2
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 le (only qualied electricians are allowed to do this!).

The patch cables with integrated sealing rings (available from MOBOTIX in dierent 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 qualied 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 specic and gener-
ally applicable countermeasures. These range from lightning capture devices and double-shielded network cables to ne-level
surge protection for end devices. When selecting the countermeasures, not only technical, but also economical aspects need to
be considered in order to nd 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-eicient 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 qualied 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.

Installing the MX-Overvoltage-Protection-Box-RJ45
1. Attach the box
Attach the MX-Overvoltage-Protection-Box-RJ45 at the mounting
position with the cable ports pointing downwards and open the
lid of the box (three screws).
2. Connect ground wire
Open the terminal screw (red circle in gure) using a regular
screw driver. Strip the insulation of the supplied or existing
ground wire for approx. 5 mm/0.2 in and push the wire through
the eight-wire plug in the center. Insert wire into terminal and
fasten terminal screw.
3. Attach the patch cable, close box
Remove both bayonet catches and the sealing plugs, insert MOBOTIX
patch cables into the cable ports and secure them using the
bayonet catches as shown. Only use MOBOTIX patch cables
with integrated sealing ring!
Mount the cover back onto the box (torque 0.4 Nm).
Installing the MX-Overvoltage-Protection-Box-LSA
1. Attach the box
Attach the MX-Overvoltage-Protection-Box-LSA at the mounting
position with the cable ports pointing downwards and open the
lid of the box (three screws).
2. Connect ground wire
Open the terminal screw (red circle in gure) using a regular
screw driver. Strip the insulation of the supplied or existing ground
wire for approx. 5 mm/0.2 in and push the wire through the eight-
wire plug at the le. Insert wire into terminal and fasten terminal
screw.
3. Prepare the installation cable
Cut the installation cable to size, push it through the cable plug
5 to 7 mm in the center, strip the cable for at least 35 mm and
separate the individual wires of the cable into twisted pairs with
20 mm shielding. Wrap the shield mesh around the cable sheath
10 mm wide so that it can rest on the contact plate of the board.
The cable will be fastened with a cable tie later on.
4. Feed the cable into the box
In order to prevent humidity entering the box, the rubber sleeve
needs to be tight against the cable. Guide the supplied cable tie
through the two cable slots as shown and pull the cable tie tight
around the cable shield to provide proper strain relief.
5. Connect the cable wires
Use an LSA PLUS wire insertion tool to insert the individual wires
into the LSA terminal. Decide on using either the EIA/TIA-568A
or B wiring standard as in the rest of the building. The color
code sticker in front of the LSA terminal shows both standards.
If no LSA PLUS tool is available, you can use a tool with inter-
changeable blades (LSA/Krone blade with setting “Low Impact”).
6. Attach the patch cable, close box
Remove right-hand bayonet catch and sealing plug, insert MOBOTIX
patch cable into the cable port and secure it using the bayonet
catch as shown. Only use MOBOTIX patch cables with inte-
grated sealing ring!
Mount the cover back onto the box (torque 0.4 Nm).
