7.2 Dismantling Optimizer
Risk of burn injuries and electric shock!
After the upstream and downstream devices of the optimizer are powered down,
measure the voltage and current with professional instrument. Only when there is
no voltage nor current can operators who wear protective equipment operate and
maintain the optimizer.
step 1 Refer to "5 Electrical Connection" to disconnect all cables of the optimizer in reverse steps.
In particular, when removing the DC connector, use an MC4 wrench to loosen the locking
parts and install waterproof plugs.
step 2 If the optimizer will be used again in the future, please refer to "3.2 Storage" for proper
storage.
