2.3.2 General Hazards and Safeguards
The power from the drive to the motor can be removed in "a safe manner". In this way, when the safe
power stage is disabled, the motor is not able to produce torque.
During normal operation, the equipment should not be accessible (i.e., protected as described in the
Risk Assessment by covers, guards, barriers, and safety interlocked gates/doors, etc.), all
covers/guards must be installed, and cabinet doors must be kept closed/locked.
During the operation of the drives, there may be uncovered live parts in the control cabinet
installation, depending on the degree of mechanical protection required by regulations governing the
site where the equipment is operated.
At the drive and/or motor, the power and control connections may be live, even when the motor is
stopped.
2.4 Thermal Hazards
CAUTION: Burn hazard - ATTENTION: risque de brûlure.
The surface temperature of the drive may reach a temperature of 80 °C, and the
motor may reach up to 100 °C (212 °F), and may become very hot in operation,
according to their protection category.
Ø Do not touch hot surfaces, measure the temperature, and wait until the drive
and motor has cooled down below 40 °C (104 °F) before touching it.
Ø It is recommended to always wear gloves when attempting to handle
DM2020 system components that have been recently operating.
2.5 Mechanical Hazards
WARNING: Mechanical hazard - AVERTISSEMENT: risque mécanique
Large motors can generate very high torque and impact or trapping hazards, which
can result in death or serious injury to personnel, or damage to equipment.
Ø Follow these safety instructions.
The motor must be properly mounted and anchored as specified in the Moog motor installation guide
supplied with the DM2020 system motor. For details, consult the Moog motor installation guide.
