Page: 6 / 20

Connecting Electrically
WARNING
_ab
Risk of electrical shock, risk of damage to equipment.
Electrical installation work must only be executed by qualified per-
sonnel that knows and observes the following regulations:
- IEC 364 or CENELEC HD 384 or DIN VDE 0100, respectively,
- IEC-Report 664 or DIN VDE 0110,
- BGV A2 (VBG 4) or corresponding national accident prevention
regulation.
●
Observe the instructions/diagram for the drive motor connection
from the motor terminal box
●
Electrically connect the drive motor
●
Connect the protective earth conductor
CAUTION
_a
Operation in the wrong direction of rotation can destroy the
vacuum and pressure pump in short time.
Prior to starting-up it must be made sure that the vacuum and
pressure pump is operated in the proper direction.
Version with three-phase motor:
◆
Determine the intended direction of rotation with the arrow (f,
42) (stuck on or cast)
◆
“Bump” the drive motor
◆
Watch the fan wheel of the drive motor and determine the di-
rection of rotation just before the fan wheel stops
If the rotation must be changed:
◆
Switch any two of the drive motor wires (three-phase motor)
Connecting Lines/Pipes
●
Connect the suction line
Installation without suction line:
◆
Make sure that the gas inlet (a) is open
●
Connect the discharge line
or
●
Connect the pressure line
Installation without discharge line:
◆
Make sure that the gas discharge (b) is open
●
Make sure that all provided covers, guards, hoods etc. are
mounted
●
Make sure that cooling air inlets and outlets are not covered or ob-
structed and that the cooling air flow is not affected adversely in
any other way
Recording of Operational Parameters
As soon as the vacuum and pressure pump is operated under normal
operating conditions:
●
Measure the drive motor current and record it as reference for fu-
ture maintenance and troubleshooting work
Operation Notes
Use
CAUTION
_a
The vacuum and pressure pump is designed for operation under the
conditions described below.
In case of disregard risk of damage or destruction of the vacuum
and pressure pump and adjoining plant components!
Risk of injury!
The vacuum and pressure pump must only be operated under the
conditions described below.
The vacuum and pressure pump is intended for
–
the suction (SV 1005 C / SV 1008 C)
–
the compression (SD 1005 C / SD 1008 C)
of
–
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in-
creased thermal and/or mechanical load on the vacuum and pressure
pump and is permissible only after prior consultation with Busch.
The gas shall be free from vapours that would condensate under the
temperature and pressure conditions inside the vacuum and pressure
pump.
The vacuum and pressure pump is intended for the placement in a
non-potentially explosive environment.
The vacuum and pressure pump is thermally suitable for continuous
operation (100 percent duty).
Version with AC-motor: the drive is equipped with a thermal protec-
tion switch.
In case of vacuum operation (SV 1005 C / SV 1008 C):
The vacuum and pressure pump is ultimate pressure proof.
In case of pressure operation (SD 1005 C / SD 1008 C):
The maximum allowed pressure on the pressure connection (b) is
2 bar abs (the nameplate of the vacuum and pressure pump indicates
the valid pressure). By means of process control and/or pressure relief
valves it must be made sure that the maximum allowed pressure will
not be exceeded.
CAUTION
_ac
During operation the surface of the vacuum and pressure pump
may reach temperatures of more than 70 °C.
Risk of burns!
The vacuum and pressure pump shall be protected against contact
during operation, it shall cool down prior to a required contact or
heat protection gloves shall be worn.
●
Make sure that all provided covers, guards, hoods etc. remain
mounted
●
Make sure that protective devices will not be disabled
●
Make sure that cooling air inlets and outlets will not be covered or
obstructed and that the cooling air flow will not be affected ad-
versely in any other way
●
Make sure that the installation prerequisites (
Ú
page 4: Installation
Prerequisites) are complied with and will remain complied with,
particularly that a sufficient cooling will be ensured
