BUSCH R5 RE 0016 B, Installation And Operating Instructions Manual

Page: 7 / 24

WARNING
_ad
In case the vacuum pump is used to convey potentially explosive
gases/gas mixtures:
Risk of explosion in the discharge area!
The process gas/gas mixture must be disposed of such that no po-
tentially explosive gas mixtures can accumulate in the discharge
area.
CAUTION
_a
The discharged gas contains small quantities of vacuum oil.
Staying in vacuum oil contaminated air bears a risk of damage to
health.
If air is discharged into rooms where persons stay, sufficient ventila-
tion must be provided for.
●
Make sure that the discharge line fits to the gas discharge (l) of the
vacuum pump
●
Make sure that the pipe will cause no stress on the vacuum pump’s
connection, if necessary use an expansion joint
●
Make sure that the line size of the discharge line over the entire
length is at least as large as the gas discharge (l) of the vacuum
pump
In case the length of the discharge line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the vacuum pump. Seek advice from your Busch representative!
●
Make sure that the discharge line either slopes away from the
vacuum pump or provide a liquid separator or a drip leg with a
drain cock, so that no liquids can back up into the vacuum pump
WARNING
_ad
Discharge lines made from non-conductive material can build up
static charge.
Static discharge can cause explosion of potentially existing oil
mist.
The discharge line must be made of conductive material or provi-
sions must be made against static discharge.
Electrical Connection / Controls
●
Make sure that the power supply for the drive motor is compatible
with the data on the nameplate of the drive motor
●
Make sure that the drive of the vacuum pump will not be affected
by electric or electromagnetic disturbance from the mains; if neces-
sary seek advice from the Busch service
In case of mobile installation:
◆
Provide the electrical connection with grommets that serve as
strain-relief
●
Make sure that an earth point is available for connection to the
earthing connection of the vacuum pump
In case the vacuum pump is used in potentially explosive atmosphere:
◆
Execute electrical circuits in compliance with applicable na-
tional explosion safety regulations
Installation
Mounting
●
Make sure that the installation prerequisites (
Ú
page 6) are com-
plied with
●
Set down or mount the vacuum pump at its location
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.
●
Connect the drive motor according to the installation instructions
for the drive motor (separate leaflet)
Note : The motor is not part of the Busch scope of delivery and is there-
fore not subject to these instructions.
●
Electrically connect the drive motor
●
Connect the protective earth conductor
CAUTION
_ad
Operation in the wrong direction of rotation can destroy the
vacuum pump in short time.
Risk of explosion!
Prior to starting-up it must be made sure that the vacuum pump is
operated in the proper direction (clockwise rotating field).
●
Determine the intended direction of rotation with the arrow (c)
(stuck on or cast)
●
“Bump” the drive motor
●
Watch the fan wheel of the drive motor and determine the direc-
tion 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)
◆
Switch the polarity (DC-motor)
◆
Replace with a drive motor with the correct direction of rota-
tion (AC-motor)
●
Connect the earthing connection of the vacuum pump to the earth
point with an earth cable
Connecting Lines/Pipes
In case the suction line is equipped with a shut-off valve:
◆
Connect the suction line
●
Connect the discharge line
Installation without discharge line:
◆
Make sure that the gas discharge (l) 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
Filling Oil
In case the vacuum pump was treated with conservation oil:
◆
Drain the remainders of conservation oil
