Due to the PWM control of the electronics the power supply unit is loaded with short, high current pul-
ses. 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 of-
ten 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.

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 tempera-
tures 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.
Packaging:
On delivery the G-BH100 is packed up in a card-
board box. When there is no connector attached
to the electrical connecting cable the lead ends
are surrounded by an ESD-prevention bag.
i
IMPORTANT!
The motor of the G-BH100 includ-
ing its connecting leads must be
protected against electrostatic
discharge (ESD).
Do not remove the ESD-
prevention bag surrounding the
lead ends until right before carry-
ing out the electrical connection
(attaching the connector, connect-
ing to a terminal strip, or the like)!

so that it might not be damaged
by outer influences and is free
from tensile stress!
Sound and vibration attenuation:
In order to reduce sound emission fasten the
G-BH100 only to parts or components that do
not conduct or emit sound easily (e.g. thin
walls, plates).
Provide sound-absorbing shims, termed
rubber / metal elements (available as acces-
sories). These are rubber pads placed be-
tween the four fixing lugs and the mounting
surface and used to absorb vibrations.
i
IMPORTANT!
During operation the surface of the
G-BH100 might have high tem-
peratures of more than 100°C!
Temperature-sensitive parts or
components, e.g. electrical wires
or cables or electronic compo-
nents must not be in contact with
or fastened to these surfaces!
CAUTION!
Burning and scalding hazard due
to hot surfaces of the G-BH100
during operation!
Provide a guard against acciden-
tal contact.
Place the rubber / metal elements (rubber pads)
between the fixing lugs (Fig. 4, # 6) and the
mounting surface.
Fasten theG-BH100 to the mounting surface via
the fixing lugs using four suitable bolts or nuts.

ised electricians only!
WARNING!
Before beginning any electrical work
on the G-BH100 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

–must be installed such that
they cannot be touched during
operation!
–must be surrounded by a
housing which is proof against
foreign bodies, humidity, etc.!
Consider the life expectancy of
the seals and gaskets!
–must be separated by suffi-
cient distances (mind protrud-
ing wire ends)!
WARNING!
Ensure that no foreign bodies, hu-
midity, etc. enter the motor interior!
The G-BH100 is operated using an electronics for
speed and direction of rotation control.
Depending on where this electronics is located
(inside or outside the G-BH100), two types of the
G-BH100 are distinguished
for external electronics (see section 5.2.1.1,
page 11):
- 2BH10 02-0AA53
for integrated electronics (see sec-
tion 5.2.1.2, page 15):
- 2BH10 02-0AB32
- 2BH10 02-0AB22
In order to determine the type of your G-BH100
refer to the type number (MLFB) on the rating
plate.
i
IMPORTANT!
The motor of the G-BH100 including
its connecting leads must be pro-
tected against electrostatic discharge
(ESD).
Do not remove the ESD-prevention
bag surrounding the lead ends until
right before carrying out the electrical
connection (attaching the connector,
connecting to a terminal strip, or the
like)!
Carry out the electrical connection
using the appropriate ESD-
prevention equipment!
5.2.1.1 G-BH100 for external electronics
With this type the electronics is located outside
the G-BH100. It is connected via the electrical
connecting cable.
i
IMPORTANT!
The main or operating direction of
rotation of the G-BH100 is the coun-
ter-clockwise rotation, given by the
arrow indicating the direction of rota-
tion on the pump lid
(see Fig. 4, # 5, page 10).
Only with the counter-clockwise rota-
tion the nominal values will be
achieved.
Clockwise rotation is only permissible
in special cases.
In this instance the G-BH100 will not
achieve its full output.
i
IMPORTANT!
The connecting cable between the
G-BH100 and the external electron-
ics must have a length of at maxi-
mum 0.5 m!
i
IMPORTANT!
When switching off the G-Bh100 or
rapidly reducing its speed a current
feed into the mains might occur.
This can be prevented by inserting a
diode (Schottky diode, size 10A) in
the 48-V supply lead (+UB)
i
IMPORTANT!
Provide good cooling of the sur-
roundings of the motor and the ex-
ternal electronics (e.g. mounting on
a good thermal conductor, sufficient
ventilation)! In case of temperatures
of > 50°C, measured at the surface
of the external electronics (Drivecon-
trol VT-D), the output power of the
pump might be reduced.

external electronics) connected to the motor ca-
ble of the G-BH100, the loose lead ends are sur-
rounded by an ESD-prevention bag. In this case,
the socket connector must first be connected to
the motor cable.
i
IMPORTANT!
The motor of the G-BH100 including
its connecting leads must be pro-
tected 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 con-
nector, connecting to a terminal strip,
or the like)!
Carry out the electrical connection
using the appropriate ESD-
prevention equipment!

motor.
i
IMPORTANT!
With the integrated-electronics type
G-BH100 the electronics is particu-
larly sensitive to overheating!
It is imperative to ensure sufficient
heat dissipation and cooling!
On delivery the integrated-electronics type G-
BH100 is not equipped with a connector at the
connecting cable. In this instance the operator
can, according to the requirements of the system,
connect a connector at his option, connect the
terminals to a terminal strip, etc.
The electrical connection is to be carried out:
according to the applicable national and local
laws and prescriptions
according to the applicable system-dependent
prescriptions and requirements
according to the applicable prescriptions of
the utility company
Via the motor connecting cable the supply volt-
age as well as the different control signals are
applied to the integrated electronics.

In order to meet the requirements bearing on
electromagnetic compatibility an EMI filter
from Messrs CORCOM, Type 6ETI F7003, 6A,
must be connected in series with the integrated-
electronics type G-BH100. The connecting cable
between the EMI filter and the G-BH100 must
have a length of at maximum 0.5 m.
i
IMPORTANT!
The main or operating direction of
rotation of the G-BH100 is the
counter-clockwise rotation, given
by the arrow indicating the direction
of rotation on the pump lid.
Only with the counter-clockwise rota-
tion the nominal values will be achie-
ved.
Clockwise rotation is only permissi-
ble in special cases.
In this instance the G-BH100 will not
achieve its full output.
i
IMPORTANT!
The connecting cable between the
G-BH100 and the external electron-
ics must have a length of at maxi-
mum 0.5 m!
i
IMPORTANT!
When switching off the G-BH100 or
rapidly reducing its speed a current
feed into the mains might occur.
This can be prevented by inserting a
diode (Schottky diode, size 6A) in
the 24-V supply lead (+UB).
