Depending on cable lengths, the cross-section of AC power cables must be at least equal to or greater than the
values provided in the table below :
Model
HPO 12-90
HPO 24-45
HPO 24-60
HPO 48-30
HPO 24-80
HPO 24-100
HPO 48-50
The type of cable (H07-VK, MX, etc.) should be defined by the installer according to the application type and
applicable 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 without insulating collars in accordance with installation standards governing AC network
input connections.
The rating of the upstream circuit-breakers should match the equipment's requirements.
Remarks :
The HPOWER chargers work as soon as they are powered on. (Input cable connected and powered)
The HPOWER chargers stop as soon as they are not under voltage (disconnected from AC network or installation
circuit breaker in OFF position).
3.2.3 Battery cable
Disconnect batteries before any wiring and junction of the connector.
Please check the compatibility of voltage, current and setting according to the battery type before switching ON the
charger.
Checking of the charge voltage
Before connecting the batteries to the charger, first check their polarity.
Equally check the battery voltage with a calibrated voltmeter. A too low voltage value on some types of batteries
show irreversible damage and impossibility to recharge.
Any damage due to incorrect connections will be excluded from the warranty.
For battery cables up to 3 meters, the cross-section of the battery cables should be at least equal to or greater than
the values provided in the table below:
