If possible, lay the Control Box on its back.
Assembling is done in revers from the steps shown.
OEM DC Control Box Special Precautions
WARNING
In case of a battery failure, (for example, due to a short circuit) the current can
cause fire or explosion. To avoid injury while performing service:
Wear safety glasses.
Wear fireproof protective gloves.
Do not perform service or maintenance work on the OEM DC Control Box if a circuit
breaker, or a power switch and a fuse are not installed.
Ensure that the circuit breaker or the power switch is off and there is no voltage on
the power connector before connecting or disconnecting the connector.
NOTICE
Since the control box does not have the reverse polarity protection, reversing the
DC source polarity causes permanent damage to the control box. Such damage
requires the replacement of the DC-DC PSU. To ensure that the polarity of the
power source wiring is correct:
Doublecheck the polarity of wires in the power connector using a multimeter. Do
not rely on the wire colors unless you have access to the battery terminals and can
see where the wires are connected.
Ensure that the wires are installed correctly in the connector terminals. Ensure that:
Wires are not loose.
Wires are fully inserted in terminals.
Ensure that the control box is grounded properly. For information on grounding, see
the OEM Control Box Installation Guide.
Ensure that the wires in the power connector can sustain the short circuit cut-off
current of the circuit breaker or fuse. For example, an AWG12 wire is rated up to
34A, so the cut-off current of the protective device must be at least 34A or lower to
protect the wire and the system.
