Safety
Use of warnings and notes
There are two types of safety instructions throughout this manual:
• Notes draw attention to a particular condition or fact, or give information on a
subject.
• Warnings caution you about conditions which can result in serious injury or death
and/or damage to the equipment. They also tell you how to avoid the danger. The
warning symbols are used as follows:
Electricity warning
warns of hazards from electricity which can cause physical
injury and/or damage to the equipment.
General warning
warns about conditions, other than those caused by electricity,
which can result in physical injury and/or damage to the equipment.
WARNING!
The ACH550 adjustable speed AC drive should ONLY be installed by a
qualified electrician.
WARNING!
Even when the motor is stopped, dangerous voltage is present at the
power circuit terminals U1, V1, W1 (L1, L2, L3) and U2, V2, W2 (T1, T2 T3) and,
depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
WARNING!
Dangerous voltage is present when input power is connected. After
disconnecting the supply, wait at least 5 minutes (to let the intermediate circuit
capacitors discharge) before removing the cover.
WARNING!
Even when power is switched off from the input terminals of the
ACH550, there may be dangerous voltage (from external sources) on the terminals
of the relay outputs.
WARNING!
When the control terminals of two or more drives are connected in
parallel, the auxiliary voltage for these control connections must be taken from a
single source which can either be one of the drives or an external supply.
