Introduction

1.1

Preface

This guide describes the planning and physical installation of the Terra 24 or Terra 54 at
its location.
The Terra 24 and Terra 54 Charge Stations are easy to install DC fast chargers for electric
vehicles. Fast chargers are electrical installations with high electric currents. Therefore
the installation must be planned carefully, and must be done by certified personnel only
(according to local standards).
The Terra 24 is physically the same charger as a Terra 54. The main difference is the out-
put power it can deliver and therefore also the input power needed. The differences of
the Terra 24 and Terra 54, and the consequences for the installation are described in a
separate section 1.3.
As the physical installation of both types is equal, they will be referred to hereafter as
Terra 54 only and this will account for both types, unless specifically stated otherwise.
Both types come in different versions, depending on the outlet types. The different ver-
sions are described in a separate paragraph.

Intended document users

This document is intended to be used by:
• Customers who purchased a Terra 54, or are in the process of ordering and want
to know in more detail how it has to be installed.
• Contractors who are responsible for site preparation and/or installation of a
Terra 24 or Terra 54.
1.3 Similarities and differences between Terra 24 and
Terra 54
The Terra 24 and Terra 54 chargers are identical in their outer appearance and physical
dimensions. The physical installation of the Terra 24 and 54 can thus be handled the
same way.
On the inside of the cabinet there are some differences. The Terra 24 has a total of 20 kW
DC power converters where the Terra 54 has a total of 50 kW converters. The Terra 24
can be updated to a Terrra 54 in a later stadium if desired. Because of the possibility to
upgrade, we advise to dimension the grid connection cable already to the power needed
for a Terra 54, to prevent high costs for groundwork if a new cable has to be laid.
It is only possible to upgrade the DC power output of a Terra 24. The AC connector on a
T24CJG will remain 22 kW after an eventual upgrade.
