PURPOSE
This Instruction Book provides assistance with site assembly and adjustment and supplies safety
and maintenance information. It refers to the drawings supplied in the contract (outline drawings,
installation drawings, wiring diagrams, etc).
To install equipment properly, the following are thus required:
- the drawings supplied in the equipment contract
- the disconnector manual
- the operating drive manual (electrical and/or manual operating mechanism)
THIS INSTRUCTION BOOK IS INTENDED FOR
Project managers.
SDCEM PRODUCT REGULATIONS
the applicable regulations in the country where they are located.
CONTACT
Your contact, if necessary, is SDCEM Services (contact details on the last page of this Instruction
Book).
As our equipment warranty is dependent on strict compliance with the information provided in this
Instruction Book, we ask you to comply with this information in all respects.

The installation concerned by the operation must be de-energised prior to operation.
Electrocution, burn, explosion, finger squeezing, cut-offs (handling, operations, etc.) hazards are
present at each operation.
Only qualified persons, complying with all safety regulations, are accredited to perform such
operations.
DANGER: Electrocution, burn and explosion hazards
Safety and operation instructions, personal protective equipment, tools
and signalling
Refer to local regulations and legislation.
SAFETY INSTRUCTIONS
Maintenance operations must be carried out by persons possessing:
• the necessary electrical accreditation,
• knowledge of the equipment in question.
Some maintenance operations must be carried out by SDCEM technicians, who can also
provide you with assistance in assembly and adjustment of your installations. Please contact
SDCEM Services for all queries (contact details on the last page of this Instruction Book).

To allow its customers to optimise disconnector maintenance in terms of safety, cost and quality, SDCEM indicates the
degrees of complexity for each operation described in the table below.
Level breakdown is as follows :
Routine servicing. Equipment servicing operations are normally described in the user manual. Minor
preventive maintenance operations not requiring disassembly; troubleshooting by standard replacement
Operations requiring
simple procedures
and/or
support equipment
(devices delivered with the
equipment, and basic tools not included in the delivery),
easy to use and to implement.
Preventive maintenance operations such as overall adjustment, failure identification and
diagnostic, repair by replacement of components or functional items, minor mechanical repairs,
carried out by a specialised technician using the tools, and the measurement and adjustment
Operations, whose procedures involve mastery of a specific technique or technology and/
or implementation of specialised support equipment. All major corrective and preventive
jeopardise equipment performance.

MAINTENANCE
All servicing and maintenance operations must be carried out on devices that are
de-energised and locked-out as per the prevailing operating procedure.
In serious polluted conditions (maritime, industrial), it is advised to monitor the
behaviour of the equipment in a corrosive atmosphere.

Should you detect a fault during maintenance operations :
Consult the FAQ (Frequently Asked Questions) in this Instruction Book or contact SDCEM Services, specifying the
references of your device.
* A silicon-based protective coating for porcelain insulators can be applied if the contamination is likely to lead to flashover

The supporting framework is not sufficiently
rigid, and needs to be strengthened.
Check bearing fixing, and retighten if
required. Strengthen the supporting
framework if required.
Check tightening of the device tube sleeves.
Should the problem persist, contact SDCEM
Services.
Repeat the adjustment procedure step by
step complying with the crank angles and
radii marked on the installation drawings.
Repeat the adjustment procedure in step 8 to
increase drive rod assembly compression.
The supporting framework is not sufficiently

Straighten the mounting plane to obtain a flat
surface, and wedge if necessary.
Adjust line-up of the disconnector link tubes,
and wedge the poles if necessary.
Reduce connection stresses.
Do not unsettle the device.
Contact SDCEM Services.
Check that current flow is less than

thermovision report to SDCEM Services for
on-site assessment.
Refer to the maintenance chart in this
Instruction Book. Run a complete operating
cycle once a year.
Refer to the maintenance chart in this
Instruction Book. Lubricate contacts, grease
mechanical joints and connecting rod
