Nameplate
The nameplate is affixed to the converter and provides the following information:
•Model name
•DC input data
•AC output data
•Certification
2.2 Mounting
Requirements for the mounting location
•A solid support surface must be available for mounting.
•The mounting location must be suitable for the weight and dimensions of
the converter.
•The mounting location should be freely and safely accessible at all times.
•Climatic conditions must be met.

7
Permitted mounting positions
•The unit can be wall-mounted or put horizontally on a flat surface like a
desk or a workbench.
Recommended clearances
•Maintain the recommended clearances to walls as well as to other objects
to ensure adequate heat dissipation.
•Minimum 25 cm from the air openings on the bottom and on the side of
the converter.
Mounting the converter
CAUTION
Risk of injury when lifting the converter, or if it is dropped
The Smart Grid Converter weighs 45 kg. There is risk of injury if the converter
is lifted incorrectly or dropped while being transported or when attaching it to
or removing it from mounting surface.
•Transport and lift the converter carefully.
•The service person should be equipped with appropriate PPE.
•Lift the converter with the help of another person or a crane.
Tools:
•4 screws (M6 or M8)
•4 washers (M5), suitable for the screws
•Screwdriver and wrench (M5)
Procedure:
1. Select a wall or a suitable flat surface capable of supporting the weight of
the converter.
2. Maintain a minimum clearance of 25 cm from converter air openings to
surrounding objects.
3. Use two lifting handles on top of the converter to lift the converter and
adjust its position.

8
4. Using four M6/M8 screws, securely attach the converter mounting brackets
to the mounting surface.
5. Once the converter is securely tightened with screws to the wall, release it
from the lifting handles.
2.3 DC Connection
DANGER
Hazard of electric shock
•Test using a meter to make sure all the circuits are de-energized. Follow
a lock-out tag-out procedure.
Ensure that the following requirement is met for installation:
•All the components installed between the DC Source and the converter
shall be rated for at least 1000 VDC and as per the applicable installation
codes.

Assembling DC connector
Cable requirements:
•Cable type: stranded, copper wire
•Cross section: 10 mm2 to 16 mm2
•Nominal voltage: UL/SCA/ICE 1000 V
•M5 16mm2or M6 16mm2cable lugs (e.g. Klauke 3R5)

9
Procedure:
•Strip cable insulation (e.g. 13mm for Klauke 3R5)
•Insert the stripped cable into the cable lug.
•Press the cable lug down with a crimping tool.
Connecting the converter
1. Ensure that the constant DC voltage source or the PV Array simulator have
sufficient rating.
2. Use a bi-directional DC source for the battery mode applications.
3. Connect the assembled DC cables according to the pin assignment shown
in Figure 2.
4. Tighten the screws on the DC terminal block with 2.5 Nm to 3 Nm torque
in order to secure the DC cables.
2.4 AC Connection
The converter can be connected either to a grid simulator or directly to the grid.
An AC breaker is to be used to protect the grid side of the converter. Use a three
phase, four pole MCCB breaker rated at 63 A (e.g. Lovato Miniature Circuit
Breaker 4P, 63 A, 10 kA, Curve B).
Assembling AC plug
AC cable between the converter and the breaker should be no longer than 2 m.
Cable requirements:
•Cable type: jacketed with five insulated conductors (e.g. Lapp Ölflex
Classic 110 5 G 10 mm2) or suitable substitute
•Cross section per conductor: 10 mm2
•5 x 10 mm2 ferrules
•Phoenix Contact contact insert Mnf Part Number: 1607474
•Pheonix Contact sleeve housing Mnf Part Number: 1855120

10
Procedure:
1. Remove the sleeve from the AC cable by 200 mm.
2. Strip the insulation of L1, L2. L3, N and the grounding conductor (PE) by
14 mm.
3. Conductors L, N and the grounding conductor (PE) should each be fitted
with appropriate size ferrules.
4. Insert the conductors according to Figure 2 and tighten the screws with
1.5 Nm ±0.3 Nm torque.
5. Place the contact insert into the sleeve housing.
6. Tighten the four screws on the front side of the contact insert with 1.5 Nm
±0.3 Nm torque.
7. Secure the sleeve housing with a cable gland.

NOTICE
Risk of equipment damage
•Ensure that L1, L2, L3, N and PE connections are done correctly.
•AC plug openings are labelled 1, 2, 3, 4 and ground, however L1
conductor must be inserted into opening 4, L2 conductor into opening 3
and L3 conductor into opening 2, N into opening 1.
