2Chapter 1 Overview

Product Identification Label
Most of information about your Elife-Drive - such as serial number, model, customer
information, etc - can be found on a label located on the front of the Elife-Drive (see
figure below). Some of these information might be requested when you contact the
technical assistance.
Compliance with the EU regulatory requirement for electrical and electronic equipment.
When your Elife-Drive is no more usable, can’t be treated as generic garbage, but
must be disposed of at a collection point for recycling of electrical and electronic
equipment, in compliance with the
WEEE
regulation (Waste of Electrical and
Electronic Equipment).

Installation and Wiring
2.1 Mounting Elife-Drive on-board
The Elife-Drive can be mounted in any orientation, but you must choose a location
in order to keep the controller
clean
and
dry
, aways from sunlight, water and ice.
When you mount the Elife-Drive on-board you should
ensure an effective heat
dissipation between the Elife-Drive and the vehicle surface.
Elife-Drive has a LED light on the front of the device that visually explains what
the driver is doing (see Section 3.1), if you want it to be visible you should take
this into consideration before choosing the location where your Elife-Drive will be
mounted.
In order to ensure the proper functioning of the Elife-Drive you must keep the
controller clean and dry and ensure an effective heat exchange between the
Elife-Drive and the vehicle surface.
Warning
The installation must be performed with an adequate heat exchange between the
Elife-Drive and the surface on which it will be placed. In Figure 2.1 is shown
a suggested installation method in order to ensure an effective heat dissipation
between the Elife-Drive and the surface on which it will be placed.
A thermal grease should be used on the rear side of the Elife-Drive heatsink to
improve the heat exchange between Elife-Drive and the surface on which it
will be placed.
Tips and Advice
If the installation method shown in Figure 2.1 is not sufficient to ensure an effective
heat dissipation from the Elife-Drive, you should install a Fan Cooler or a Liquid
Cooler on your Elife-Drive.

A recommended installation method in order to ensure an effective heat
dissipation between the Elife-Drive and the surface on which it will be placed. A thermal
grease should be used between the Elife-Drive and the surface on which it will be placed.

2.2 Connections
Elife-Drive on the front has different types of connectors:
High Power Connections
The three-phase alternating-current generated by Elife-Drive is supplied
through the U,V,Wterminals.
The
B+
and
B-
are the positive and negative terminals to connect to your
battery.
You must connect an external fuse between the
B+
terminal and the positive
battery terminal. (see Section 2.2.1)
Low Power Connections
14 pins female connector for Digital, Analog Input and Command Signal
6 pins female connector for Output Signal
8 pins female connector for Digital Communications CANopen®and RS232
30 pins female connector for Universal Feedback Interface

2.2 Connections 7

2.2.1 High Power Connections
High power connections are provided by: 3-phase supply terminals (
U
,
V
,
W
) and
two terminals for battery connections (B+,B-).
In order to connect correctly Elife-Drive, you should use the following instructions:
1. Connect the the battery negative cable to the B- terminal.
2.
An external fuse (See Table 2.1) must be fitted from the
battery positive
to
terminal B+ to avoid damage to the controller.
Elife-Drive models haven’t any fuse already installed.
Note
Table 2.1: Fuse size in accordance with the Elife-Drive SR Series
ELIFE-DRIVE TYPE FUSE RATING
SR Size 1 63 A
SR Size 2 250 A
SR Size 3 700 A
* All models of SR Series require an external fuse.
3.
Connect the U, V, and W motor phases to the 3-phase supply terminals
(U,V,W).
The tightening torque must be:
for SR Size 1 =5.5 Nm for all five Power Connections
for SR Size 2 =11 Nm for all five Power Connections
for SR Size 3 =14 Nm for all five Power Connections

8Chapter 2 Installation and Wiring

When connecting the high power cables, make sure that the feedback cable
passes as far as possible from the power cables, possibly with a different path,
this to avoid electromagnetic interference.
