Battery Cable; Cable Linking The Earth To The Installation - Cristec UECPS3/12–16/2D Manuel D'utilisation

3.2.3 AC distribution cable
The cross-section of the 2, 3 or 4 wire distribution (depending on model) must be 2,5mm². The installer
should define the type of cable (H07-VK, MX...) according to the type of application and the applicable
standards.
The current in the cable must not exceed 10A.
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) of the AC source must be connected
to the terminal provided for the purpose, and this must be done before connecting any other terminals (earth
bar).
The neutral cable must be connected to the output terminal "N" of the circuit breaker.
The phase cable must be connected to the other output terminal of the circuit breaker.

3.2.4 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 CPS3 charger is equipped with 4 output terminals:
K4: - BAT (minus set of batteries)
K5: +BAT D (plus engine battery for marine-type applications)
K6: +BAT 1 (plus battery set 1)
K7: +BAT 2 (plus battery set 2)
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
UECPS3/12-16
UECPS3/12-25
UECPS3/12-40
The type of cable (H07-VK, MX, etc.) must be set by the installer depending on the type of application and
standards.
Keep the cable bushings on the lower side of the cabinet to avoid possible damage of the cables on the metal
walls of the cabinet and guarantee insulation between the active conductors and the electrical ground.

3.2.5 Cable linking the earth to the installation

The unit'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 earth bar located inside the unit (see appendix
p.34).
This cable's cross-section should be at least 2.5mm², type HO7-VK and equipped with an appropriate
terminal.
