Communication Specifications Communication protocols Frequency band ZigBee NB-IoT/LTE CAT M1/3G
(Optional) Zig-Bee: 2.4GHz It is a wireless metering system based on ZigBee Mesh network technology, featuring a unique design that combines low cost and high accuracy measurements. Every metering device on the ZigBee network is associated with a ZigBee gateway. The role of the gateway is to periodically collect all measurements, gathered by the devices, to forward them to the Meazon Cloud for storage and further analysis. Meazon Cloud gives users the ability to monitor the current energy consumption, set alarm rules, control their devices (on/off switching) and schedule them to operate in a desired pattern. Meazon DinRail Cerberus is a rail-type device with small size (2 DIN), which can be easily installed and is capable of monitoring, measurement logging and controlling:
up to three separate power lines / loads a three-phased load an entire electrical panel (single-phase, dual-
phase, three-phase) It comes with three current transformers to measure any electrical load without limitations. The internal relay can be externally driven using On/Off commands or internally using Meazon scheduling.

Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Safety Information Use this product only in the manner described in this manual. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Product may be cleaned with a clean soft towel. Do not use liquids to clean. Product is not water resistant. If the unit gets wet, do not touch it. Power off and allow it to dry thoroughly before further operation. Do not disassemble the product. There are no spare parts for this, it is not repairable. If physical damage to the product occurs, do not use. Replace with a new one. RF exposure warning :
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.

Installation from non-
qualified individuals may lead to electrocution or heavy damage to the devices. Wiring requirements: 16 or 18AWG Solid cable. Make sure that the maximum amperage to be measured does not exceed the maximum value the provided Meazon DinRail Cerberus can measure. We recommend to protect Meazon DinRail Cerberus with a maximum 10Amps circuit breaker. Suggested Miniature Circuit Breaker
- S201-C10 (Rated Current 10A) Any other circuit breaker with the same specification can also be used. INSTALLATION 1) Locate the main electrical panel. 2) Turn the power off for safety reasons. 3) Locate the current conductors to be measured. Current transformers will be added at those conductors WARNING! Current conductors should be between the electrical fuse and the circuit breaker (in case of metering electrical loads separately), or between protection relay and electrical fuse (in case of measuring total consumption). 4) Check inside the electrical panel for the optimal location to place the Meazon DinRail Cerberus and the 10A protective circuit breaker. 5) Place the protective circuit breaker at the rail. 6) Place the DinRail and push to lock it at the rail of the electrical panel. In this installation guide DinRail Cerberus will be called DinRail for brevity reasons. Installation in a three-phase panel Meazon Electronic Systems S.A., 57 N.E.O Patron - Athinon Str. 26442, Patra, Greece info@meazon.com support@meazon.com +30 2610 430000 www.meazon.com 7 CTs installation Connect each of the three Current Transformers outputs (black wires) to contacts CT1 B, CT2 B and CT3 B. Connect each of the three Current Transformers inputs (red wires) to contact CT1 R, CT2 R, and CT3 R. Locate the current conductors to be measured starting from phase L1 and pass it through the coil of the CT (current transformer) by opening the coil of CT. WARNING! Make sure the direction of the arrow illustrated at the CT terminals to the load. Reconnect the current conductor. Repeat the process for the other two phases (L2, L3). Power lines L1 L2 L3 installation Connect the phase voltage L1, L2, L3 and N with the terminal L1, L2, L3 and N. WARNING! Make sure that the sequence of phases 1, 2 and 3 of the DinRail is strictly L1, L2 and L3, otherwise measurements will be incorrect. Check the entire procedure again before completing the installation
(the sequence of the phases of DinRails input, the sequence of the Current Transformers connection and the direction of the arrow of each CT).
