de Gier GW series Installation Manual page 7

1.3 General safety instructions
• Read the installation manual carefully and in full;
• Check that the delivery is complete before starting to install the motor gearbox;
• Strictly observe the step-by-step procedures set out in the installation manual;
• Observe all of the information in the installation manual, in particular all information relating to safety, use,
maintenance and servicing;
• Keep the installation manual in a safe place throughout the entire service life of the product;
• Switch off power to the motor gearbox before starting to work on the motor gearbox or in its immediate vicinity;
• Clean up the hazard area and leave it before switching the power back on;
• Improper installation, commissioning, maintenance etc. of the motor gearbox can lead to personal injury and/
or material damage due to the high torque of the motor gearbox;
• Operate the motor within its electrical ratings to avoid damage to the motor, drive train or other parts of the
system;
• Do not allow people to stand under or close to suspended loads;
• Never loosen screws, couplings or other parts while the drive train is under load;
• Also observe national legislation and guidelines regarding working conditions and safety.
1.4 General safety instructions
• Switch the power off before starting to work on the motor gearbox or the system and lock it out (for example,
with a padlock) to prevent it from being switched back on. This also applies to auxiliary circuits, such as limit
switches or standby heating. It is not sufficient to switch off the controller by selecting 'stop' or '0'. The motor
gearbox may also continue to operate in the «Stop» or «0» position in response to higher-level functions, such
as signals from wind or rain sensors;
• Attached or driven parts may have a shorter service life than the motor gearbox itself;
• With a three-phase supply, swapping two of the phases reverses the direction of rotation of the motor gearbox,
which can affect the operation of the limit switch mechanism;
• De Gier supplies motor gearboxes that are self-braking, but this function may not be effective under certain
conditions. We strongly recommend that for hoisting applications you use a motor gearbox equipped with a
mechanical brake and mount a fall-arrest brake on the driven shaft;
• With attached or driven components there is a risk of becoming trapped or injured. Amongst other things, the
safety distances set out in EN 349 and EN 13857 must be observed and suitable precautions must be taken,
such as safety devices or a dead-man vigilance system;
• The housing of the motor gearbox can reach temperatures above 60°C / 140°F. Fit a protective cover if
necessary, depending on the location of the motor gearbox;
• Despite careful planning and compliance with all regulations, some risks cannot be prevented.
1.5 Qualified staff
All activities described below must be performed by qualified staff. Qualified staff means persons who, based
upon their training, experience and/or education, have obtained sufficient knowledge of the applicable standards,
provisions, accident prevention regulations and operating conditions and are thus able to identify and avoid
potential hazards during relevant activities (for instance, installers recommended by De Gier). Approval by the
safety officer for the overall plant or system is always required before work may be carried out.
