NOTE! Ferroamp does not take responsibility for damages on the product caused by incorrect or careless installation.
NOTE! We recommend that you use end terminals for all connection points that have multi-threaded conductors.

• Do not work alone. In an emergency, someone else’s presence may be necessary!
• The electrical installation must comply with national / local laws and regulations, appropriate standards and applicable requirements from recognized organizations.
• The electrical installation must be carried out by a qualified installer and in accordance with the applicable electrical standard.
• Ensure that the location of the EnergyHub Wall never is an obstacle to an emergency evacuation path. In accordance with national & local laws.

Required tools

• Screwdrivers:
  • TX – 30
  • TX – 20
  • Slot drive 1×5 mm
• Cable peeler and cutter (1 – 10 mm²)

Placement
NOTE! Ferroamp does not take responsibility for installations where the following stated criteria are not met.
Make sure that the chosen location for installation is in line with the following criteria:

• Indoor environment protected from rain and direct sunlight.
• Space is well ventilated (if the EnergyHub Wall is placed in a sealed area then forced ventilation must be provided to ensure adequate heat dissipation)
• Ambient temperatures must not fall below 0 ° C and not exceed 45 ° C
• The environment must be non-condensing, relative humidity below 95%
• There must be at least 50 mm free space underneath the cabinet to have sufficient cooling.
• Have free space around the cabinet according to the following figures:

EnergyHub Wall can be mounted up in two ways:

• A. Standing: Adjust the cabinet feet to correct height. Secure the cabinet to the wall through the indicated wholes.
• B. Wall mounted: Use the indicated holes and mount the cabinet on the wall. Ensure that the mounting surface can carry a weight up to 60 kg.

Mount EnergyHub XL module

1. Unscrew the following 6 screws, and remove the cover plate.
2. Lift in the EnergyHub XL -module , make sure that the AC and DC connections are to the left (the text on the front of the XL-module should be readable from the front of the cabinet).
3. Fasten the EnergyHub – module with four of the M6x12 bolts.
4. Screw the cover plate back on
5. Fasten the Display unit with the remaining two M6x12 bolts according to the figure below.

Connection to facility distribution board

NOTE! To calculate correct cable dimensions you can use Ferroamp’s online cable calculator, available at www.ferroamp.com under the support section.
Connect the EnergyHub Wall to the building’s electrical distribution board according to the figure below. Section off with B40 fuses.

1. Main fuse,
2. Main breaker,
3. Electrical distribution board,
4. Fuse for EnergyHub and
5. Breaker for EnergyHub

AC connector

Peel off 14 mm, attach end terminal, insert in correct position according to image below, and tighten with 1.8 Nm.

• Make sure that the EnergyHub XL Single is connected correctly to the incoming AC-grid.
• It is recommended to install an external AC circuit breaker for the whole system.

DC Nanogrid connector
NOTE! If you will not connect a DC nanogrid for the system you are installing, go ahead and skip this section (ex. If the system only will be used for adaptive current equalization (ACE) and measuring/data collection).
NOTE! The DC nanogrid cable does not require an M-conductor unless you are installing a Powershare system (a DC nanogrid with two or more EnergyHub systems).
Peel of 14 mm, attach end terminal, insert in correct position according to image below, and tighten with 1.8 Nm.

• Make sure that the EnergyHub XL Single is connected correctly to the DC nanogrid.
• If you have a Powershare system, it is recommended to install an external circuit breaker that sections of your EnergyHub from for the DC nanogrid.

Cable connections

1. Insert AC connector to EnergyHub XL – module.
2. Place the capacitor box in the bottom of the cabinet and insert the attached DC nanogrid connector to the EnergyHub XL -module.
3. Connect the incoming DC nanogrid connector to the capacitor box.

Current transformers (CT) – connection and placement

NOTE! If you have purchased Rogowski CT 600/1200/1800A skip this section and see the separate instructions provided in the Rogowski-kit.

1. Route the CT cable into the cabinet through the preferred cable gland. The supplied CT has a cable length of 10 m.
   NOTE! To extend the cable you need to use a twisted pair cable. The total sling resistance needs to be below 10 Ohm. See table below for the relation between conductor area and max cable length between CT clamp and EnergyHub.

2. Attach the CT cable to the CT connector according to picture bellow. From left to right; white, red, blue, black, yellow and green.

3. To ensure proper connection and eventual cable extension, measure the resistance between the pairs. All pairs (red/white, black/blue, green/yellow) should show similar resistance.

4. Attach the contact housing, make sure to attach the strain relief around the CT cable isolation.

5. Connect the CT connector to the CT adapter, then connect the CT adapter to the EnergyHub XL module.

6. The current transformers (CT) need to be placed around the main AC feed, one clamp on each phase, L1, L2 and L3. The order and direction have no significance since it is detected automatically. The importance lies in that each phase has a clamp. The clamps need to be placed between (B) and (C).
   A. Main fuse
   B. Electricity meter
   C. Distribution board (breaker/electric panel)
   D. EnergyHub-system
   E. Other single and three-phase loads NOTE! Do NOT place the current transformers between (C) and (D) or between (C) and (E).

7. When attaching the CT-clamps make sure that they close properly.

Ethernet connection
To enable data reporting and software updates in EnergyHub, a working connection to the Internet is required, either via Ethernet or via USB modem.
Connect a network cable to the display port’s network port. The following requirements apply to the Internet connection:

• IPv4 address as well as functioning DNS server and NTP server are assigned using DHCP.
• Outgoing traffic to the internet must work properly. Information on specific ports and more details can be found at www.ferroamp.com in the FAQ page.

Mounting of front cover
NOTE! Ferroamp recommends that you proceed with the commissioning before attaching the front cover. This way you will have easier access when troubleshooting and resetting the EnergyHub.

1. Slide on the front cover from the front with top and bottom aligned to the wall cabinet.
2. Attach the top mushroom screws on both sides of the cabinet.
3. Attach the bottom mushroom screws on both sides of the cabinet.
