Testing
Service personnel may test circuits by energizing them briefly without suspending the lock out / tag out
procedure. This may only be done when no other work is being performed by any other person on the
equipment being tested.
It is extremely important that all remote Start switches are tagged with the "Do Not Operate" tag to pre-
vent inadvertent operation of the equipment during these periods.
Responsibilities
●
It shall be the responsibility of the maintenance and service personnel to make sure this proced-
ure is adhered to.
●
It shall be the responsibility of the maintenance and service personnel's immediate supervisor to
instruct their personnel on this procedure.
●
It shall be the responsibility of the Safety Officer to administer the lock out / tag out procedure.
1.3 Notes on switching the machine back on
CAUTION
Residual voltages
► After switching off the machine, wait at least 10 seconds before you switch it back on again, so
that stored residual voltages can dissipate.
► Please note that longer waiting periods apply when working on the power supply.

1.4 Other instructions
1.4.1 Environmentally-friendly disposal of materials and components
Our products are manufactured using only materials and parts that can be easily separated and dis-
posed of in an environmentally-friendly way.
NOTICE
Observe the applicable regulations
The company operating the system has sole responsibility for the proper, environmentally-friendly dis-
posal of machines, working materials, consumable materials and wear parts.
► Please observe your national statutory provisions for waste disposal and environmental protec-
tion.
1.4.2 Use of original accessories and spare parts
Only use original spare parts and authorized accessories. The use of other parts will affect safety and
will invalidate the liability for any consequential damage.

1.4.3 ESD guidelines
1.4.3.1 What does ESD mean?
Fig.5: ESD label
Almost all of the modules in use today are equipped with highly integ-
rated Metal-Oxide-Semiconductor (MOS) blocks and components. The
manufacturing techniques used mean that these electronic components
are extremely sensitive to overvoltage and thus to electrostatic dis-
charge.
The abbreviation for such modules is "ESD" (Electrostatic Sensitive
Device). "ESD" is used internationally. The following symbol on cabinet
rating plates, racks or packaging indicates that components which are
sensitive to electrostatic discharge have been used and thus that the
modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be per-
ceived by humans. Such voltages occur if a person touches a component or module without earthing
themselves. Components that are exposed to such overvoltage do not generally appear to be defect-
ive immediately - incorrect behavior starts after the component or module has been in operation for
some time.
1.4.3.2 Important measures to protect against static charging
► Most plastics can easily become charged and must therefore be kept away from at-risk compon-
ents.
► Always ensure that people, the workplace and packaging are safely earthed when handling elec-
trostatic sensitive components.
1.4.3.3 Handling ESD modules
As a general rule: Only touch electronic modules if you must carry out work on the modules. In that
case, make sure that you do not touch the pins or printed conductors when you pick up flat modules.
Only touch components if you are earthed by one of the following measures:
●
You are wearing an ESD wristband.
●
You are wearing ESD shoes.
●
You are wearing ESD shoe earthing strips on an ESD floor.
Immediately before you touch an electronic module, discharge your own body by touching a conduct-
ive and earthed object (such as unpainted parts of a switch cabinet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g. plastic
films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD foam,
ESD bag or container).
Do not bring modules near visual display units, monitors or televisions. Keep a minimum distance of
10 cm to monitors.
1.4.3.4 Measurements and modifications to ESD modules
Only perform measurements on modules if one of the following conditions is fulfilled:
●
You are using an earthed measuring device (e.g. via PE conductors)
●
You are using a potential-free measuring device and discharge the measuring head before the
measurement (e.g.by touching an unpainted metal part of the controller casing).
► Always use an earthed soldering iron if you carry out any soldering work.

1.4.3.5 Dispatching ESD modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags or
metal sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before packaging.
Use conductive expanded rubber, ESD bags, domestic aluminum foil or paper, for example.
NEVER use plastic bags or film.
► If the module has integral batteries, ensure that the conductive packaging does not touch or short
circuit the battery terminals and, if necessary, first cover the terminals with insulating tape or
material.
1.4.4 Validity of Document
This document contains instructions for the installation of WPC modules.
The work described in this manual is largely identical for all WPC types:
●
If the work required for specific machines should differ from the standard procedure, this will be
indicated with reference to the machine number, series and delivery state.
●
Diagrams should be seen as examples e.g. the diagram of a SIPLACE WPC5 or a different paint
finish does not mean that the following information only applies to the type shown.
