Safety
Motor protection switch
Make provision for an on-site motor protection switch for devices without a plug! The
minimum requirement is a thermal relay/motor protection switch with temperature
compensation, differential triggering and anti-reactivation device in accordance with
the local regulations. In case of sensitive mains, make provision for the installation on-
site of other protective equipment (e.g. overvoltage, undervoltage or phase failure re-
lay, etc.).
Residual-current device (RCD)
Comply with the regulations of the local energy supply company! The use of a residual-
current device is recommended.
If persons come into contact with the device and conductive fluids, secure the connec-
tion with a residual-current device (RCD).
There is a danger of bacterial infection when using the device in fluids hazardous to
health! Thoroughly clean and disinfect the device after dismantling and prior to further
use. The operator must ensure the following:
▪ The following protective equipment is provided and worn when cleaning the device:
– Closed safety goggles
– Breathing mask
– Protective gloves
▪ All persons are informed about the fluid, the associated danger and its correct handling!
▪ The following protective equipment must be worn:
– Safety shoes
– Safety helmet (when using lifting equipment)
▪ Always hold the handle to transport the device. Never pull the power supply cable!
▪ Only use legally specified and approved lifting gear.
▪ Select the lifting gear based on the existing conditions (weather, attachment point,
load, etc.).
▪ Always attach the lifting gear to the attachment points (handle or lifting eyelet).
▪ The stability of the lifting equipment must be ensured during operation.
▪ When using lifting equipment, a second person must be present to coordinate the pro-
cedure if required (e.g. if the operator's field of vision is blocked).
▪ Persons are not permitted to stand beneath suspended loads. Do not carry suspended
loads over workplaces where people are present.
▪ Wear the following protective equipment:
– Safety shoes
– Safety gloves for protection against cuts
– Safety helmet (when using lifting equipment)
▪ Locally applicable laws and regulations for work safety and accident prevention must be
complied with.
▪ Disconnect the device from the mains and secure it against being switched on again
without authorisation.
▪ All rotating parts must be at a standstill.
▪ Provide adequate aeration in closed rooms.
▪ When working in chambers and closed spaces, a second person must be present for
safety reasons.
▪ Take immediate countermeasures if there is a build-up of toxic or suffocating gases!
▪ Clean the device thoroughly. Disinfect devices that are used in fluids hazardous to
health!
▪ Make sure that there is no risk of explosion when carrying out any type of welding work
or work with electrical devices.
▪ Wear the following protective equipment:
– Safety shoes
– Ear protection (in accordance with the notice of the work regulations)
▪ Work area of the device is not a recreational area. No persons are allowed in the work
area during operation.
▪ The operator must immediately report any faults or irregularities to their line manager.
▪ If safety-endangering defects occur, the operator must immediately deactivate the
device:
– Malfunction of the safety and monitoring device
– Damage to the housing parts
– Damage to the electrical equipment
▪ Never reach into the suction port. The rotating parts can crush and sever limbs.
