	1	1.1 Levels of hazard warnings
	1
		These operating instructions use the following hazard levels to indicate
	1
		potentially hazardous situations and important safety regulations:
	1	DANGER
	1
		Indicates an imminently hazardous situation which, if not
	2	avoided, will result in death or serious injury. Compliance with
	2	the measures is mandatory.
	2	WARNING
		Indicates a potentially hazardous situation which, if not avoided,
	2
		could result in death or serious injury. Exercise extreme
	2
		caution while working.

6maintained and otherwise used by qualified, trained and authorised

6	technical staff.

6Only authorised specialists are permitted to install the device, to carry out a test run and to perform work on the electrical installation.

	6
	6	1.3 Basic safety rules
	7	Any safety hazards stemming from the device must be re-evaluated
	7	once it is installed in the end device.
		Observe the following when working on the unit:
	7	; Do not make any modifications, additions or conversions to the

7device without the approval of ebm-papst.

81.4 Electrical voltage

	10	; Check the electrical equipment of the device at regular intervals, refer
	11
		to chapter 6.2 Safety test.
	12	; Replace loose connections and defective cables immediately.
	12	DANGER
	12
		Electrical load on the device
	12	Risk of electric shock
		→ Stand on a rubber mat if you are working on an electrically
	13
		charged device.
	14	WARNING
		Terminals and connections have voltage even with a
	14	unit that is shut off
		Electric shock

→ Wait five minutes after disconnecting the voltage at all poles before opening the device.

G3G250-MW50-01	Operating instructions

Translation of the original operating instructions

CAUTION

In the event of failure, there is electric voltage at the rotor and impeller

The rotor and impeller are base insulated.

→ Do not touch the rotor and impeller once they are installed.

CAUTION

If control voltage is applied or a speed setpoint is stored, the motor automatically restarts, e.g. after a power failure.

Danger of injury

→Keep out of the danger zone of the device.

→When working on the device, switch off the mains

supply voltage and secure the latter from being switched on again.

→Wait until the device stops.

→After working on the device, remove any used tools or other objects from the device.

1.5Safety and protective functions

DANGER

Missing safety device and non-functioning safety device

If there is no safety device, you could be seriously injured, for example if you reach into the running device or your hands are sucked into it.

→Operate the device only with a fixed and isolating safety protection and a fixed guard grille.

The guard must withstand the kinetic energy of a fan blade detaching at maximum speed.

→The device is a built-in component. You, the owner/

operator, are responsible for providing adequate protection for the device.

→Shut down the device immediately if you detect a missing or ineffective protective feature.

1.6Electromagnetic radiation

Interference from electromagnetic radiation is possible, e.g. in conjunction with open and closed-loop control devices.

If unacceptable emission intensities occur when the fan is installed, appropriate shielding measures have to be taken by the user.

NOTE

Electrical or electromagnetic interferences after integrating the device in installations on the customer's side.

→Verify that the entire setup is EMC compliant.

1.7Mechanical movement

DANGER

Danger of injury from open blower

Gas escapes. When the blower is open, you come into contact with rotating and electrically live parts. Escaping gas may also cause explosions.

→ Never open the blower.

DANGER Flying parts

Missing safety devices may cause balancing weights or broken fan blades to be ejected at high speeds, causing bodily harm.

→ Take appropriate safety measures.

WARNING Rotating device

Long hair, loose items of clothing and jewellery could become entangled and pulled into the device. You could be injured.

→Do not wear any loose clothing or jewellery while working on rotating parts.

→Protect long hair by wearing a cap.

WARNING Flying parts

Missing safety devices may cause fan blades to be ejected at high speeds, causing bodily harm.

→Take appropriate safety measures.

The safety devices must prevent contact with rotating parts and the printed circuit board.

1.8Deflagration

DANGER

Gas escapes through leaky housing after deflagration

Danger of injury

→After a deflagration, check that the housing of the gas blower is tightly sealed.

→Replace any gas blower with a leaky housing.

DANGER

Fire and deflagration hazard

The gas blower is not approved according to Ex protection guidelines. Rotating parts can scrape against stationary parts. This may cause sparks and chips. The surface temperature may rise, resulting in a fire.

→Check which hazards arise from installing, operating, servicing or disposing the gas blower in conjunction with your device.

Prevent these hazards.

Carry out all appropriate measures to this purpose.

1.9Emission

WARNING

Depending on the installation and operating conditions, a sound pressure level greater than 70 dB(A) may arise.

Danger of noise-induced hearing loss

→Take appropriate technical safety measures.

→Protect operating personnel with appropriate safety equipment, e.g. hearing protection.

→Also observe the requirements of local agencies.

1.10 Hot surface

CAUTION

High temperature at the electronics enclosure

Danger of burn injuries

→Ensure that sufficient protection against accidental contact is provided.

1.11Transport

NOTE

Transport of blower

→Transport the blower in its original packaging only.

→Secure the blower so that it does not slip, e.g. by using a clamping strap.

1.12Storage

;Store the device, partially or fully assembled, in a dry and weatherproof manner in the original packing in a clean environment.

;Protect the device from environmental impacts and dirt until the final installation.

;We recommend storing the device for a maximum up to one year to guarantee proper operation and longest possible service life.

;Even devices explicitly suited for outdoor use are to be stored as described prior to being commissioned.

;Maintain the storage temperature, see chapter 3.6 Transport and storage conditions.

;Please make sure that all screwed cable glands are fitted with dummy plugs.

1.13 Disposal

When disposing of the device, please comply with all relevant requirements and regulations applicable in your country.
