OPERATIONAL CONDITIONS
The user's attention is drawn to the following notes:
1) The vibrator is approved to the following certification:
ATEX Directive 2014/34/EU
Certificate Numbers CML16ATEX3122X and IECEx CML 16.0050X
ATEX Coding/marking II2D Ex tb IIIC T___° C Db IP66
HAZARDOUS AREA CLASSIFICATION;
Zone of Use (Dust) Zone 21 & 22
Rated Temperature Refer to tables on pages 4 & 5
Ingression Protection (BSEN60529) Main Enclosure IP66
Terminal Box IP66
The equipment is certified for use in ambient temperatures -20°C to +40°C.
The X in our certificate number signifies a special condition of use and applies to vibrators mounted in
orientations other than with a horizontal shaft and also those intended for use with variable speed drives;
i. The user is advised that this equipment is fitted with thermistors, RTDs or thermostats. Mounting the motor in any
orientation, other than with the shaft horizontal, requires the thermistors, RTDs or thermostats to be connected to a
suitable controlling and regulating device, as defined in article 1(b) of European Directive 2014/34/EU, and when
located in hazardous area , shall be covered by an appropriate EC or EU Type Examination Certificate.
This condition does not apply to the smaller vibrators in the Invicta range from BLz03 up to BLz25, fitted with ball
bearings.
ii. The user is advised that this equipment is fitted with thermistors, RTDs or thermostats, therefore, when a vibrator
mounted in any orientation is fed from a variable speed drive, it shall be connected to a suitable controlling and
regulating device, as defined in article 1(b) of European Directive 2014/34/EU, and when located in hazardous
areas, shall be covered by an appropriate EC or EU Type Examination Certificate.
iii. Where the vibrator is installed into a fixed installation where the installation is intended to minimise the risk from
electrostatic discharge the installer must ensure the vibrator is suitably earthed. The vibrator should not be operated
without a suitable earth in place. Regular checks as part of routine inspections should establish that the earth is
intact.
iv. The user shall mark the vibrator with information relevant to the chosen Variable Speed Control as detailed in BS
EN60079-0, clause 29.15.
2) The equipment has not been assessed as a safety related device (as referred to by directive 2014/34/EU Annex II,
clause 1.5).
3) Installation of this equipment shall be carried out by suitably trained personnel in accordance with the applicable
Code of Practice (EN60079-14).
4) Inspection and maintenance of this equipment shall be carried out by suitably trained personnel in accordance with
the applicable Code of Practice (EN60079-17).
Repair of this equipment shall be carried out by suitable trained personnel in accordance with the applicable Code of
Practice (EN60079-19).
The manufacturer offers a full repair service.
5) Components to be incorporated into or used as replacements in the equipment shall be fitted by suitably trained
personnel in accordance with the manufacturer's documentation.

6) If the equipment is likely to come into contact with aggressive substances, then it is the responsibility of the user to
take suitable precautions to prevent it from being adversely affected, thus ensuring that the type of protection is not
compromised.
a) Aggressive Substances: e.g. acidic liquids or gases that may attack metals or solvents that may affect
polymeric materials (such as seals)
b) Suitable Precautions: e.g. regular checks as part of routine inspections or establishing from material
data sheet that it is resistant to specific chemicals.
7) Some Invicta vibrators are provided with either an integral cast lifting point or provision for the use of eye bolts. Users
are to ensure that shackles, eye bolts or any other required lifting equipment used are sufficiently rated to safely lift the
weight of the vibrator. The weight of each vibrator is included in the information stamped on the vibrator nameplate.
Users should also ensure that any lifting accessories or equipment is used in accordance with the manufacturer’s
instructions and the user’s codes of practice. The lifting points should be inspected for defects prior to each lifting
operation.
Note: The lifting points are designed solely to lift the vibrator only. Users should not, under any circumstance, use the
lifting point on the vibrator to lift any other plant or machinery that the vibrator may be mounted to.
WARNING: The shaft assembly inside the vibrator contains eccentric weights and is free to rotate as the
vibrator is lifted.
This potential shifting of the weight distribution should be taken into account when lifting the vibrator into
position.
Disclaimer
Invicta Vibrators are certified to comply with the European Directive 2014/34/EU (ATEX Directive) as described. It
remains the responsibility of the user to ensure that the equipment is correctly selected and rated for the environment in
which it is to be used in accordance with European Directive 99/92/EC (also known as ATEX 137 or the ATEX Workplace
Directive) and regulations 7 and 11 of the Dangerous Substances and Explosive Atmospheres Regulations 2002
(DSEAR).
Important Safety Note:
It is the responsibility of the intended user of the BLz vibrator to ensure that the installation and usage instructions
contained in this manual are fully understood before any attempt to install or use the vibrator is made. Failure to
understand and adhere to these instructions could result in fire, electric shock, explosion or serious personal injury.
This manual should be retained throughout the life of the vibrator and referred to whenever necessary.

‘L’ SERIES VIBRATOR INSTALLATION AND MAINTENANCE
RECEIPT AND STORAGE
Each vibrator is tested and inspected on completion. Whilst every care is taken during transit they should be
inspected on receipt and any defects immediately reported to the carrier and supplier. When not for immediate
use, they can be stored for up to two years if kept in a clean, dry and temperate atmosphere, free from
vibration. After more than 2 years of storage the bearing grease should be replaced before the motor is used.
INSTALLATION GUIDANCE NOTES:
Mechanical: Inspect vibrator for any physical damage and check that rotor shaft rotates freely. Remove paint
masking stickers from motor mounting holes. ALL mounting surfaces MUST be flat and free of paint, dirt and
scale. Fixing bolts should be tightened as recommended below and tightness checked after initially running
the vibrator. Bolts and nuts should not be reused. Please ensure there is at least 50mm of clearance between
the vibrator and any surrounding static structure.
IMPORTANT - GAPS BETWEEN THE VIBRATOR FOOT AND MATING SURFACES AND INCORRECT
BOLT TIGHTNESS WILL CAUSE BOLT BREAKAGE AND DAMAGE TO THE VIBRATOR.
Fixing bolt tightening: Use Grade 8.8 bolts with Grade 8 self locking nuts, torqued to values below. Figures
below apply to un-plated dry threads.
Where capscrews are used with locking nuts, Grade 10 nuts must be fitted.
Use plain washers for BLz 03 - BLz 24 (aluminium frames) Not BLz22. If washers are used for BLz22 - BLz80
(cast iron frames) Not BLz24, hardened washers (PSN 612 to DIN 6916 or BS EN 14399-6) must be fitted.
BLz 75 - 80: Half turn method.
In exceptional circumstances where tooling is not available, the half turn method may be used.
PSN 661 – High Strength nut
PSN 612 – Hardened washer under
bolt head and nut
PSN 780 - High strength bolt
Remove any paint, dirt or scale from all mating surfaces.
Fit hardened washer (PSN 612) under bolt head and nut. Pre-tighten until all mating surfaces are in contact.
Mark nuts and bolts as shown in fig. 2 and slog nut one half turn until marks are as shown in fig. 3.

Electrical
Check insulation resistance and if less than 1 megohm DO NOT USE, consult a qualified electrician. Perform
a continuity resistance check between the external earth point and end covers, terminal box lid and nameplate,
if the resistance is more than 1.0 ohms between the earth point and any of the aforementioned items, DO NOT
USE, consult a qualified electrician. Note: this continuity check should be performed after each removal and
re-fitting of the end cover and terminal box lid.
A flexible cable and suitable cable gland must be used to connect between the vibrator and supply junction
box.
The cable gland shall comply with EN60079-0 and have an IP rating equal to or better than IP66 (see table on
pages 4 & 5 for cable entry thread sizes). The supply must be suitably fuse protected. 4 core cable to be
used with flexible conductors type; 24/0.20 (BLz 03); 50/0.25 (BLz 05 – BLz 40); 56/0.30 (BLz 45 – BLz 50);
80/0.40 (BLz 60/61 – BLz 75-80): BLz 24 to BLz 80 are fitted with thermistors as standard and require a 2
core cable with flexible conductors type 30/0.25. The external earth cable must have a cross sectional area of
at least 4mm²
Flexible conductors must be terminated with insulated crimp on ring terminals, or ring terminals fitted with
insulating sleeves for L1, L2, L3 and earth. Plain soldered ends for thermistor connections T1 and T2.
If thermistors are not required leave the blanking plug in the cable entry hole.
BLz Vibrators are suitable for a 3 phase 50Hz or 3 phase 60Hz electrical supply. BLz vibrators are
rated for continuous duty. The insulation class of the winding will be either ‘F’ or ‘H’ as indicated on
the nameplate. Starting can be direct on line via inverter or soft start. Each vibrator MUST BE
INDIVIDUALLY PROTECTED against overload. Each overload should be of the delayed magnetic-circuit
breaker type to prevent tripping during the high starting current requirement of vibrator starting. The overload
size should be selected based on the full load current and starting current values listed on pages 11 & 12.
NOTE When operating vibrators at speeds above pole speed the out of balance force MUST be reduced or
DAMAGE WILL OCCUR; see Page 30 for correct percentage reduction.
VOLTAGE RANGE
The voltage range data on pages 11 & 12 (230-690v 50Hz and 230-575v 60Hz) is served by four distinct
windings* thus:
* Except BLz40 8 Pole which uses group 43 windings for 460-480v 60Hz.
The winding group number and Hertz appears in the vibrator designation and on the nameplate Thus a BL25-
14/4 400v 50Hz machine will be designated BL25-14/4/01/50.
It is essential that the correct Winding (group) is used with the specified electrical supply. Noncompliance with the above instructions will result in electrical failure.
Terminal post nuts should be tightened to the values given in the table below.
