Warning
Dangerous electrical voltage
Touching live parts will c ause an electric shock, which can result in death or severe
injuries:
– atanopenslot:
– CMMS: [EXT]
– CMMD: [ EXT1/EXT2]
– at the connection or connector:
– Motor [X6] ( CMMS )/[ X6.1/X6.2] (CMMD)
– Po w er supply [X9]
1. Equip the open slot [ EXT] (CMMS)/[EXT1/EXT2] ( CMMD) with the missing module or
cover plate.
2. Install the product in a control cabinet.
Caution
Unexpected movement of the drive
If the following conditions are fulfilled during the Power ON process:
– Output stage enable is enabled (DIN4 = 24 V)[X1.21][ X1.1.21/X1.2.21]
– Controller enable is enabled ( DIN5 = 24 V)[ X1.9] [ X1.1.9/X1.2.9]
– Setpoint value specified via control interface “Fieldbus/analogue input”
the drive (motor/axis) will start moving; it is then capable of causing crushing injuries in
the operating area of the drive.
• Make sure the controller enable ( DIN5)[X1.9][ X1.1.9/X1.2.9] is disabled during the
Power ON process (= 0 V).
Caution
Hot housing surfaces
The housing can reach a temperature of > 80° C during operation, which can cause
burns.
1. Install the product in a control cabinet.
2. Check the temperature of the housing before touching it (e.g. by slowing moving the
back of your hand towards the housing).
