(Caution)
1) Approximately one hour after activating, the temperature on part of outer surface reaches
nearly
70 o C. Therefore, be careful not to get burn, immediately after turning off power.
2) Watch out for a hot heat sink.
Operations while removing a heat sink can cause failure.
3) As a heat sink (approx. 250 g to 300 g) is heavy comparing with the product weight (approx.
900 g). Keep a balance when taking out the board.
(Note)
While fixing a heat sink to a chassis, Amp
Unit cannot be removed. Meanwhile, even
if screws are taken out, the heat sink is not
removed from the chassis.
(The heat sink is removed together with
Amp Unit. They cannot be removed
separately.)
