1.7 Responsibility
As a basic principle, electronic devices are not fail-safe.
The operator and/or the contractor setting up the machine
or system is responsible for ensuring that the drive
switches to a safe state if the device fails.
The “Electrical equipment of machines” section in DIN EN
60204-1; VDE 0113-1, “Safety of machinery” describes the
safety requirements for electrical control units. These are
provided for the safety of people and machines and must
be observed in order to retain the functional capability of
the machine or system.
An emergency stop feature does not have to result in the
voltage supply to the drive being switched off. To avoid
dangerous situations, it may be useful for individual drives
to remain operational or for specific safety procedures to
be initiated.
The effectiveness of emergency stop measures is
evaluated by means of a risk assessment for the machine
or system and its electrical equipment and is determined
by selecting a circuit category according to DIN EN 13849
“Safety of machinery – Safety-related parts of control
systems”.

2.4 Description of DGM Modular drive controller
The DGM Modular drive controller is a device for the speed control of three-phase AC motors.
The drive controller can be integrated in the motor (with the standard adapter plate) or fitted close to the motor (with the
wall mounting adapter plate).
The permitted ambient temperatures specified in the technical data refer to operation at nominal load.
In many cases, higher temperatures may be permitted after a detailed technical analysis.
These have to be approved by Bonfiglioli Riduttori S.p.A. on a case-by-case basis.

The cross-section of the supply line must be designed according to the transfer category
and maximum permitted current. The contractor commissioning the device must ensure
protection for the power line.
DANGER!
Risk of death due to revolving mechanical parts!
Death or serious injury!
De-energise drive controller and secure it against being restarted.
Only allow appropriately qualified staff to install the drive controller.
Only use staff who are trained in mounting, installation, commissioning and handling.
Always ground the device in accordance with DIN EN 61140; VDE 0140, NEC and other relevant
standards.
The drive controller must be grounded with the motor according to relevant regulations. Non-
compliance may result in death or serious injury.
If spring elements are not used when assembling the adapter plate, there must be an extra connection
between the motor and drive controller to produce a correct protective conductor connection
Unused open cable ends in the motor connection box must be insulated.
Use suitable line circuit breakers with the prescribed nominal current between the mains and drive
controller.
Mains connections must be hardwired.

Tab. 1: Ambient conditions
◼Ensure that the housing type (protection class) is suitable for the operating environment:
- Ensure that the seal between the motor and the adapter plate is inserted correctly.
- All unused cable screw connections must be sealed.
- Check that the cover of the drive controller is closed and bolted down tightly.
- Size A –C (4 x M4 x 28) 2 Nm,
- Size D (4 x M6 x 28) 4 Nm
Although the drive controller can, in principle, be painted
later on, the user must nevertheless check the material
compatibility of the intended paint. The DGM Modular is supplied in RAL 9005 (black) as
standard.
Disassembling the circuit boards (even for the purpose of
painting the housing sections) renders the warranty void!
Mounting points and sealing surfaces must be kept free of
paint for purposes of EMC and grounding!
DAMAGE TO PROPERTY POSSIBLE
Failure to comply with the information may result in
damage to the drive controller!
When attaching a cover with integrated foil keypad, be
absolutely sure that the flat ribbon cable is not pinched.
DAMAGE TO PROPERTY POSSIBLE
Failure to comply with this requirement may eventually
result in the loss of the protection class (particularly in
respect to seals and fibre-optic elements).
