▪
When disconnecting the power supply: disconnect the current-carrying cables
first, before separating the earth connection.
▪
The length of the conductors between the power supply stress relief and the
terminal block itself must be as such that the current-carrying wires are tautened
before the earth wire is in case the power supply is pulled loose from the stress
relief.
CAUTION
Do NOT perform the test operation while working on the indoor units.
When performing the test operation, NOT only the outdoor unit, but the connected
indoor unit will operate as well. Working on an indoor unit while performing a test
operation is dangerous.
