Battery Cable; Cable Linking The Earth To The Installation - ENAG CDS3 Manuel D'utilisation

The PE conductor (commonly called "earth", the green and yellow wire) of the AC source must be
connected to the charger on the terminal provided for the purpose, and this must be done before connecting
any other terminals.
Please refer to the relevant diagram in the chapter "user interface area".
The rating of the upstream circuit-breakers should match the equipment's requirements.
Remarks:
The CDS3 chargers are working as soon as they are connected (connected and supplied AC network cable)
The CDS3 chargers are stopped as soon as they are not anymore under voltage (disconnected AC network
cable or circuit breaker of the installation in OFF position).
BE CAREFUL: if the ON/OFF charger accessory is used, the charger can be stopped but nevertheless still
being under voltage (dangerous voltage).
Power limiting switch
A switch on the outside of the case (the cable lead-in side) limits the charger's output power (on position 1) :
This may prevent the differential circuit-breaker at the beginning of the 400VAC line from tripping.

3.2.3. Battery cable

Please check imperatively the compatibility of voltage, current and setting according to the connected
battery type before switching ON the charger.
Check of the charge voltage
Before connecting the batteries to the charger, imperatively check the polarity of the batteries.
Equally check the battery voltage thanks to a calibrated voltmeter. A too lower voltage value on some types
of batteries can point out an irreversible damage of them and so an impossible recharge.
The CDS3 charger is equipped with 3 output terminals:
K4: - BAT (minus set of batteries)
K5: +BAT 1 (plus battery set 1)
K12 : +SP (external battery isolator input particular case)
Be careful: a direct connection of a battery on the SP terminal could destroy the charger,
imperatively connect a battery isolator between the battery and the SP terminal).
Up to 3 metres, the cross-section of the battery cables should be at least equal to or greater than the values
provided in the table below:
Model
CDS3/24-150-TRI
The installer should choose the type of cable (H07-VK, MX...) according to the type of application and the
applicable standards.
The cable bushings or glands must remain on the lower side of the case to avoid the linking cables being
damaged on the metal walls of the case and to guarantee insulation between the active conductors and the
electrical exposed conductive part.

3.2.4. Cable linking the earth to the installation

The charger's case should be connected to the installation's earthing system in accordance with current
standards governing the relevant application.
To that effect, connect the installation-to-earth cable to the earthing screw located inside the charger (see
chapter "user interface area").
This cable's cross-section should be at least 2.5mm², type HO7-VK and equipped with an appropriate
terminal.
