2Installation
The installation section will take you step by step through the
process of installing a ESS Power Case.
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.
2.1 Placement
NOTE! Ferroamp does not take responsibility for installations
where the following stated criteria are not met.
NOTE! Make sure that the ESS Power Case and the ESS Battery are
positioned close enough for the premade battery cables to reach.
Make sure that the chosen location for installation is in line with
the following criteria:
•Indoor environment protected from rain and direct
sunlight.
•Ambient temperatures must not fall below 0 °C and
not exceed 45 °C.
•The environment must be non-condensing, relative
humidity below 95%.
•Have free space around the ESS Power Case
according to the following figures:
•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 ESS Power
Case never is an obstacle to an emergency
evacuation path. In accordance with national
and local laws.

1. To remove the front cover by first unscrew the two side
thumbscrews (1 & 2), slide the front up (3) and lift it off (4).
Finish with unscrewing the PE-cable from the baseplate (5).
2. To access the distribution panel, unscrew the two slotted
screws in the bottom front (2) and the top (3) then lift of the
poke protection:
3. Mount the base plate on the wall, see dimensions for position
of mounting holes (mm):

2.1 ESS Battery connection
1. Cut of the ring terminals from the premade battery cables
included with the ESS Battery Controller.
2. Poke holes in the multi grommets and feed Bat+, Bat- and PE
cables through the smaller grommets.
3. Attach isolated ferrules and connect to the cables to the
following terminals:
4. Make sure that all terminals are tightened to 2.5 Nm, use a
torque wrench.
5. Remove the cable grommet for the RJ45 cable, poke a hole,
cut it open along one side and attach it around the
communication cable.
6. Connect the communication cable from the ESS Battery to
the outer port, “CAN 2”:
7. The ESS Battery is now connected!

2.2 Connection of SSO:s (1-3)
If you do not have any SSOs you can skip this section.
NOTE! To calculate correct cable dimensions you can use
Ferroamp’s online cable calculator, available at
www.ferroamp.com under the support section.
1. Feed the SSO cable through one of the larger grommets:
2. Feed through ~40 cm of cable for and peel of ~35 cm of
isolation.
3. Connect to the following terminals:
4. Make sure that all terminals are tightened to 2.5 Nm, use a
torque wrench.
5. If you have 2 or 3 SSOs just repeat the steps above for each
SSO.

2.3 DC nanogrid connection
NOTE! To calculate correct cable dimensions you can use
Ferroamp’s online cable calculator, available at
www.ferroamp.com under the support section.
1. Depending on the cable diameter used for the DC link, feed
the cable through the M32 cable gland or one of the larger
grommets.
2. Peel of the cable isolation according to instruction in section
2.2.
3. Connect the DC nanogrid cable (L+, L- & PE) to the following
terminals.
4. Make sure that all terminals are tightened to 2.5 Nm, use a
torque wrench.
2.4 Connection overview
1. Verify the correct polarity of all connected cables.
2. Control that all terminals are fastened with 2.5 Nm.
3. The key holes seen in the image below can be used to secure
the cables with extra cable ties if needed.
•Make sure that the DC nanogrid is connected
to correct terminals.

2.5 Install ESO Modules
The ESS Power Case can be configured with either 1 or 2 ESO
Modules depending on the power configuration of the ESS
System.
1. Unpack the ESO Module and remove the pre-installed
connector (if it has one), the back connector will not be needed
for the installation. To remove the connector unscrew the two
screws then pull off the connector.
2. Align the ESO module against the back plate. Look from the
side to ensure that the connectors are aligned.
3. When alignment of the connector is good gently lower the
ESO module in place, one module at the time:
a. 1 x ESO Module:
b. 2 x ESO Module
4. Secure the ESO Modules with the mounting bracket as seen in
the images above.

2.6 Assembly finish
1. Mount the poke protection and re-attach the PE-cable to the
base plate.
2. Attach the warning sticker on the poke protection.
3. Commission the system, see section 3.
4. Re-attach the PE cable to the baseplate before mounting the
front cover.
3Commissioning –Start up
NOTE! If this is the first time starting up the EnergyHub system
you need to follow the commissioning guide included with the
EnergyHub (available at www.ferroamp.com ).
1. Turn on the EnergyHub.
2. Close the breaker on the ESS Power Case.
3. Close the breaker on the ESS Battery and press the start
button for 5 seconds until it rings.
4. When the system is on the battery will calibrate during the
first 24 hours. During this time, you should set the charge
reference to 1 kW in the system configuration
(www.portal.ferroamp.com).
5. After the calibration has finished you can configure the
battery in the system configuration after you desired use
case.
