First Device – If this is your first myenergi device the zappi will opt to set the device as Master and turn the in-built vHub on. If you are adding to an existing myenergi eco-system, the device will opt to set as slave and turn the in-built vHub off. -
Page 5: Randomised Delay: How It Works
Overriding the delay To override the delay simply press the ‘+’ button on the zappi or press the ‘charge now’ button displayed in the pop-up message within the myenergi app. If the delay is overridden your charge will start/stop immediately. -
Page 6: Defaulting To 'Eco+' Mode
If the default schedule does not suit your requirements, or your electricity tariff’s off-peak hours differ from the schedule set, you can amend your schedule at any time from the zappi menu or within the myenergi app. To adjust your schedule in the app navigate to the ‘Set Boost Parameters’ option, select start time and set the number of hours you want your charger to boost for. -

Installation Mounting NOTE Care should be taken to maintain the IP rating of the unit • • Ensure grommets and bungs provided are fitted, the O-ring behind the cover is seated correctly and that the incoming power and CT cables are fitted using an appropriate size and type of gland. zappi must be fixed to a flat vertical surface. - Page 13 Step 3: Step 4: Remove all 8 screws from the enclosure There are 4 possible cable entry positions, and carefully lift away. carefully decide which one you are going to use from the above image. You will need an IP65 or above rated cable gland. Carefully drill a hole into the unit to match the size of your cable gland.

Note: if using the rear cable entry, remember to insert the mains cable before mounting to the wall! Wiring WARNING! - Page 15 8.2.2 Supply The single phase zappi should be connected to a 230V/240V nominal AC supply. The supply should run from a dedicated 32A circuit breaker. The 3 phase zappi should be connected to a 400V, 4 wire, 3 phase supply. The supply should run from a dedicated 3 pole 32A circuit breaker.

Page 20: Ct Sensor Installation
CTs can be wired to any myenergi device with CT inputs (e.g. eddi, zappi or harvi). This allows for flexible installation as a CT can be wired to the nearest device. Ideally the grid CTs should be wired to the master device. - Page 21 The positioning of the Grid CT sensor is crucial, please take note of the following when deciding where best to install the sensor: The sensor can be connected to any myenergi device with a CT input e.g. the eddi, zappi (wired •...
- Page 22 CTs can also be used to limit the power drawn from the supply: Additional CTs can be connected to any myenergi device with a CT input that is linked to the network. • The arrow on the bottom of the sensor must be pointing in the direction of normal power flow (e.g.
- Page 23 • Phase 1). This helps to avoid phase shifting / phase misalignment. 8.3.8 CT Can do’s Can be wired to ANY myenergi device in the network. • harvi can be used to make ANY CT wireless • Cable can be extended up to 100m (must use twisted-pair cable e.g. one pair of CAT5).

Load Balancing / Current Limiting / Load Curtailment CTs can also be used to limit the current drawn by myenergi devices to avoid overloading circuits; this is referred to as load balancing or load curtailment. There are four different ways to limit current and they can be used alone or combined for more complex situations. - Page 26 The CT should be clipped around the Live cable of the supply feeding the diverter. The arrow on the CT should be pointing away from the diverter (towards the consumer unit). Wire the CT to the nearest myenergi device or use a harvi if a wireless connection is needed.

If zappi detects a problem with a welded contact, then the display will show RLY WELDED! If this happens and the fault cannot be reset by pressing the button for three seconds, then please contact myenergi technical support at support@myenergi.com Patent Reference GB3577354... - Page 28 8.6.5 Over-current If there is a problem with the equipment on the EV which charges the vehicle’s battery, too much current may be drawn from the supply. If this happens, zappi cannot control the charge rate as expected and it could lead to problems with overheating or tripping the main circuit breaker to the zappi.
