The JMB Series is the most powerful and feature rich electric fence energizer JVA has made to date. This continues JVA’s push for technical superiority in the area of Monitored Electric Fencing and IP Energizers(R). While the JMB was specifically designed for Game Parks and Exclusion Fencing, they are also well suited to any large permanent electric fence. The highest powered JMB produces a stunning 46J of stored energy. At this time the JMB series consists of 6 models:
JMB32-ZM1
JMB32-ZM2
JMB32-ZM50
JMB25-ZM1
JMB25-ZM2
JMB25-ZM50
The ZM1 is a single zone energizer designed for large complex fences.
Four of the six internal fence connection terminals are used for the ZM1 model. The Fence return and the Ground reference are optional.
| Energizer | Fence |
|---|---|
| Feed 1 | Start of fence 1 |
| Ground | Fence earth |
| Feed 2 | Not Used |
| Return 1 | (Optional) End of Fence 1 |
| Reference Ground | (Optional) Earth |
| Return 2 | Not Used |
The ZM2 is a dual zone energizer. Designed for powering and monitoring two sections of a boundary fence.
All six internal fence connection terminals are used for the ZM2 model. The Fence returns and the Ground reference are optional.

The ZM50 is a single zone energizer with loop monitoring. Designed for powering and monitoring a single boundary fence with the ability to detect and display a fault in one of up to 50 programmable sectors.
Four of the six internal fence connection terminals are used for the ZM50 model. The Ground reference is optional. If it is used, it should be connected to a separate earth stake.

Please read the entire manual before proceeding.
Design and build the fence. (Beyond the scope of this manual.) Ask your distributor for help if required.
Decide where the JMB is to be mounted. If on an external wall it should be housed within an equipment box and not in direct sunlight.
Mount the housing by using screws through the mounting holes in the corners of the box.
If you are using a 12V battery, connect the battery leads to the PCB terminals. Do not connect to the battery yet.
If you are using AC power, connect the power pack 24V to the PCB terminals. Do not turn AC on yet.
Wire the Fence and Earth cables to the fence terminals.
Put short pieces of wire into any unused cable glands to seal them.
While the Energizer is designed not to start when first powered up, make sure it is not going to hurt you if it does start up!
Connect the battery leads to the battery (if used).
Turn AC power to the 24Vdc power pack on (if used).
Power LED's will light up and the Wi-Fi LED will start blinking code 1 (1 flash each second).
Replace the front cover (lid).
Connect to the energizer using the virtual keypad (in the next section).
Arm (turn on) the JMB. The virtual keypad will now be able to show the fence voltage(s) and current(s).
Find and remove any faults on the fence.
Consult the main users manual for more information
The JMB Wi-Fi module can be used to configure and control the JMB. The Wi-Fi module defaults to Access Point (AP) Web server mode.
Before you start make sure the Wi-Fi status LED is blinking code 1.
Open the Wi-Fi settings on your phone and connect to the JMB's Wi-Fi.
The Name of the Wi-Fi (SSID) from your Energizer is JVA_Jumbo_xxxxxx where xxxxxx is the Serial Number of the unit. Select this SSID to connect to it.
The connection is password protected.
The default password is: jvasecure
Enter the password and press CONNECT
