3.2.2. Cable from the public AC power supply network or generator
All CPS3 battery chargers can operate automatically and equally on single phase networks from 85 to 265VCA and
from 47 to 65Hz.
Generators:
The CRISTEC battery chargers are designed to operate from a generator.
Be careful:
In some cases, the generators can produce high over voltages, in particular during starting
phase. Before connecting the charger, please check its compatibility with the characteristics ofthe
generator: power, voltage, overvoltage, frequency, current... It’s highly advised to disconnect the charger
from the AC network during the generator starting phase.
The power cable must be connected to screw terminal board K1 (PE, ACN and ACL terminals):
PE : Earth
ACN : Neutral
ACL : Phase
Depending on line lengths, the cross-section ofAC power cables must be at least equal to or greater than the values
provided in the table below:

The type ofcable (H07-VK, MX, etc.) should be defined
by the installer according to the application type and the
enforceable standards.
For applications where the electricity network may be
either 115VAC or 230VAC, always choose the cross-
section recommended for 115VAC.
Always use cable markers with insulating collars in
accordance with installation standards governing AC
network input connections.
The PE conductor (commonly called "earth", the green
and yellow wire) ofthe 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
3.2.3. Battery cable
Please check imperatively the compatibility ofvoltage, 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 ofthe 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 ofthem and so an impossible recharge.
The CPS3 charger is equipped with 5 output terminals:
K4: - BAT (minus set ofbatteries)
K5: +BAT D (plus engine battery for marine-type applications)
K6: +BAT 1 (plus battery set 1)
K7: +BAT 2 (plus battery set 2)
K12 : +SP (external battery isolator input particular case)
Be careful: a direct connection ofa battery on the SP terminal could destroy the charger,
imperatively connect a battery isolator between the battery and the SP terminal).

, the cross-section ofthe battery
cables should be at least equal to or greater than the
values provided in the table below:
The installer should choose the type ofcable (H07-
VK, MX…) according to the type ofapplication
and the applicable standards.
The cable bushings or glands must remain on the
lower side ofthe case to avoid the linking cables
being damaged on the metal walls ofthe case and
to guarantee insulation between the active
conductors and the electrical exposed conductive
part.
interface area”.
The rating ofthe upstream circuit-breakers should match the equipment's requirements.
Remarks:
The CPS3 chargers are working as soon as they are connected (connected and supplied AC network cable)
The CPS3 chargers are stopped as soon as they are not anymore under voltage (disconnected AC network cable or
circuit breaker ofthe installation in OFF position).
BE CAREFUL: ifthe ON/OFF charger accessory is used, the charger can be stopped but nevertheless still being
under voltage (dangerous voltage).
