El interruptor (o interruptores) de batería no podrán considerarse como el dispositivo de protección contra fallos para las cadenas de batería y el cableado asociado.
La capacidad nominal de interrupción de los interruptores de batería instalados dentro de los sistemas de energía es de 10kA. Por lo tanto, la corriente de cortocircuito máxima posible de una cadena de batería de 48V deberá limitarse a menos de 10kA o la impedancia interna total de la cadena de batería deberá ser de más de 5,7mΩ.
Si se utiliza un dispositivo de protección externo contra fallos con una capacidad nominal inferior, deberá seleccionar baterías con una impedancia interna adecuada.
Connecting the Battery Cables (if applicable)
Poder desconectar la corriente del fallo posible de la cadena de batería.
Estar ubicado lo más cerca posible del terminal de salida de la cadena de batería y
El dispositivo de protección contra fallos deberá:
Deberá instalarse un dispositivo de protección (tal como un interruptor de circuito o fusible) en serie con uno de los cables de batería de cada una de las cadenas de batería.

This section applies to APS3-059, APS3-061 and APS6-059 dc power systems only.

Before You Start

Ensure that all the circuit breakers at the front of the APS dc power system and the external battery circuit breaker (close to the battery output terminals) are switched OFF.

Before proceeding check you have:

Battery cable clamp(s) one for APS3 models, three for APS6-059

2 x 25mm blunt ended screws per clamp

1 x 16mm sleeve (50mm long) per clamp

Battery cable (see specification below)

Battery Cable Specifications

No battery cables are supplied with APS3-059, APS3-061 and APS6-059 dc power systems. All battery cables must meet the following specifications and no other cable sizes must be used.

Cable Style and Size:

UL 1283*, 4AWG (25mm), multi-strand cable

Cable Length:

3m (10 feet) maximum

*Required to maintain approval compliance.

Step 1 – Prepare cable clamp

Cut off the two inside posts of the battery cable clamp to enable the battery cables and sleeve to fit.

Step 2 – Strip cable and fit sleeve

Strip approximately 17mm (3/4”) of the insulation from the cable ends. We recommend fitting cable ferrules over the cable ends.

Feed both battery cables through the 16mm sleeve.
