Safety and Residual Risks

Before beginning to work on the GBH100 or the system carry out the following steps for both the G-BH100 and the entire system

– switch off electricity, – lock against restart, – ensure absence of electricity, – ground and short-circuit instal-

lation,

– cover or bar adjacent live

parts,

– depressurise both pipes and

pump.

Do not wear long, loose hair! Use a hair net! Never wear wide, loose clothes!

Transport and handling as well as assembly and disassembly may be carried out by trained and responsible personnel only!

Operation of the G-BH100 only

– with the gases as indicated in

section 2, "Intended Use"!

– with the values as indicated in

section 3, "Technical Data"!

Check pipes/hoses and vessels for sufficient strength!

Check pipe / hose connections for tightness!

Operation of the G-BH100 only when completely assembled and securely fastened to the mounting surface!

Check fasteners for secure fixing at regular intervals!

After loosening clampings and fastening elements some parts and components are only held in place by their centrings or seatings or are no longer held in place at all so that they might fall down.

Take the necessary care during disassembly and assembly!

Operation of the G-BH100 only with the pump lid assembled!

Disassembly of the pump lid only after the impeller has come to a complete standstill! Consider impeller run-out!

Operation of the G-BH100 only with the pipes / hoses connected to the suction and delivery branches!

WARNING!

In case of operation with open suction or delivery branches (drawing-in of gases from or discharge of gases into the surroundings) a piece of pipe or hose with a length of at least 120 mm must by all means be connected to the branch in question in order to prevent the impeller from being reached by fingers!

Disassembly of the pipes / hoses connected to the suction and delivery branches only after the impeller has come to a complete standstill!

Consider impeller run-out! Do not reach into the G-BH100

through open suction or delivery branches!

Do not insert any objects into the GBH100 through the openings!

Operation of the G-BH100 only with the motor cap assembled!

Disassembly of the motor cap is prohibited.

Work on electrical installations may be carried out by trained and authorised electricians only!

The electrical connections must be surrounded by a housing which is proof against foreign bodies, humidity, etc.!

Consider the life expectancy of the seals and gaskets!

Ensure that no foreign bodies, humidity, etc. enter the motor interior!

For heat dissipation and cooling provide a minimum distance of 15 mm on each side except for the pump lid side on which a smaller distance of at least 2 mm is permissible!

Burning and scalding hazard due to hot surfaces of the G-BH100!

Do not touch during operation! Let the unit cool after shut-down!

Provide a guard against accidental contact!

Safety and Residual Risks

The motor of the G-BH100 including its connecting leads must be protected against electrostatic dis-

charge (ESD). Do not remove the ESD-prevention bag surrounding the lead ends until right before carrying out the electri-

cal connection (attaching the connector, connecting to a terminal strip, or the like)! Carry out the electrical connection using the appropriate ESDprevention equipment!

Danger zone:

Hazard:

 Severing of limbs.  Drawing-in and entanglement of

hair.

Protective measures:

 Operation only with the pipes /

hoses connected to the suction and delivery branches! In case of operation with open suction or delivery branches (drawing-in of gases from or discharge of gases into the surroundings) a piece of pipe or hose with a length of at least 120 mm must by all means be connected to the branch in question!

 Use a hair net!

Danger zone:

The vicinity of the unit during operation with open suction or delivery branches (drawing-in of gases from or discharge of gases into the surroundings)

Hazard:

 Injuries due to contact with pres-

surised fluids or due to sudden acceleration of parts.

 Injuries due to parts thrown out of

the unit.

Protective measures:

 Ensure that fluids discharged into

the surroundings are not expelled close to people (e.g. work stations on machines)!

 During work on or near the unit

wear personal protective equipment!

Due to the PWM control of the electronics the power supply unit is loaded with short, high current pulses. For this reason the supply voltage must be blocked or filtered by means of a capacitor (low ESR type, suitable type for high frequencies, high current switching, > 1000 µF) for noise suppression.

Usually this capacitor is part of the power supply unit. Switch-mode power supplies, however, are often provided with a capacitor of only very small capacitance at the output so that this kind of pulses result in interference. In this case an additional capacitor must be connected as close to the motor as possible.

Gas intake and ambient temperature t [°C]

Fig. 3: Permissible total differential pressure / conversion factor

For the permissible total differential pressure at an intake and ambient temperature of +15°C [+59°F] see the table in section 3.1, "Nominal and Limiting Values Pump", page 6.

In order to calculate the permissible total differential pressure for other intake and ambient temperatures proceed as follows:

 Find out your system-dependent gas intake and ambient temperature.  Establish the conversion factor valid for these conditions by means of the above diagram.

(In order to do so mark your intake and ambient air temperature on the temperature axis. Draw a vertical line from this value to the point of intersection with the curve. Now draw a vertical line from the point of intersection to the conversion-factor axis where you can read the conversion factor then.)

 Multiply the established conversion factor with the max. permissible total differential pressure at

15°C as given in the table in section 3.1, "Nominal and Limiting Values Pump", page 6.

 The result will be a pressure value. This is the max. permissible total differential pressure valid

for your G-BH100 at your system-dependent intake and ambient temperature.

4 Transport and Handling

Packaging:

On delivery the G-BH100 is packed up in a cardboard box. When there is no connector attached to the electrical connecting cable the lead ends are surrounded by an ESD-prevention bag.

IMPORTANT!

The motor of the G-BH100 including its connecting leads must be protected against electrostatic discharge (ESD).

Do not remove the ESDprevention bag surrounding the lead ends until right before carrying out the electrical connection (attaching the connector, connect-

ing to a terminal strip, or the like)!
