1. Safety instructions
1.3 General safety instructions
• Read the installation instruction carefully and entirely;
• Prior to starting the installation of the motor gearbox, you should check if it was delivered complete;
• Strictly adhere to the order of action, as stated in the installation instruction;
• Observe all information in the installation instruction, in particular the information with regard to safety, usage,
maintenance and conservation;
• Keep the installation instruction during the entire lifecycle of the product;
• Interrupt the supply voltage of the motor gearbox, before you start working on the motor gearbox or in the direct
vicinity;
• Clean up the hazard area and get out of it before switching the power back on;
• The high torque of the motor gearbox may cause personal injury and/or material damage as a result of incorrect
assembly, commissioning, maintenance work, etc.;
• Avoid exceeding the electrical connection values. This could lead to damage to the electric motor, power train and
other parts of the construction;
• Do not allow people to be present under or near suspended loads;
• Under no circumstance screws, couplings or parts may be loosened when the driven system is under load;
• In addition, you should observe national legislation and directives with regard to working conditions and safety.
1.4 General safety instructions
• Interrupt the power supply before working on the motor gearbox or the installation and protect the power supply
(for instance with a padlock) to prevent the power from being switched back on again. This also applies to auxiliary
circuits, such as limit switch or stationary heating. Switching off the control using ‘stop’ or ‘0’ will not suffice. Due to
hierarchically higher functions, such as wind or rain signals, the motor gearbox could also start running in ‘stop’ or
‘null’ position;
• Connected or driven parts could have a shorter technical lifespan than the motor gearbox itself;
• In case of a three-phase power supply, swapping two out of the three phases will result in a reversed rotation
direction of the motor gearbox, which might also affect the functioning of the limit switch system;
• De Gier supplies motor gearboxes that are self-locking. Under certain circumstances the self-locking may not work.
Therefore, in case of lifting applications, we strongly recommend the use of a motor gearbox equipped with an
electric motor that is fitted with a mechanical brake and to apply a fall-stop protection to the driven shaft;
• Due to connected or driven parts, there is a risk that you get entrapped and injured. Observe the safety distances in
accordance with NEN EN 349 and NEN EN 13857 and take suitable precautions., Ensure safety provisions for instance
or a dead-man’s vigilance system;
• The housing of the motor gearbox could reach temperatures in excess of 60°C/140°F. Apply a protective cover,
depending on the positioning of the motor gearbox;
• Despite meticulous planning and observation of all regulations, not all risks can be prevented.
1.5 Qualified staff
All work described hereafter must be performed by qualified staff. Qualified staff means persons who, based on their
education, experience and/or training, have gained sufficient knowledge of the applicable standards, provisions, accident
prevention regulations and operational circumstances, and are able, as such, to recognise possible hazards during the
work, as well as avoid them (e.g. installers recommended by De Gier B.V.).
At all times permission from the person responsible for the safety of the total installation is required before commencing
the work.
