Lockout-tagout
of
machines
and installations
(L.O.T.O.)
To perform operations, absent of voltage (L.O.T.O.), the device
shall be locked and tagged to non-hazardous voltage values.
The following section is based on the lockout-tagout at several
points according to:
1.Restrict access to the work area to prevent entry of unauthor-
ised personnel.
2.It shall be disconnected and isolated from the supply network
or connection to the converter.
3.Once disconnected, the STRING shall be sectioned into parts
with voltages below 75 VDC.
4.The terminals of these parts shall be protected by insulating
caps designed for this purpose.
5.Given that the batteries are an energy storage system, it is
impossible to make certain points of the system free of volt-
age. If there is any exposed point where the voltage cannot be
eliminated, the terminals will have to be tagged, indicating the
voltage value at that point.
6.Prior to conducting any work, the voltage shall be measured
at the point where the work is to be done. Some points may
be energised directly from the batteries.
•
If it is not possible or takes too long to cut the current, try to
disengage them by means of an insulating element (wooden
strip or board, rope, wooden chair ...).
Whenever a battery is not installed on the STRING, make sure
that the power terminals at the front are protected against
accidental contact given that the terminals are energised.
Make sure that the output and input connection cables are not
short-circuited.
Make sure there is no short circuit between positive and neg-
ative terminals at any point.
Make sure there is always protective insulation on the output
and input cables and a reliable connection.
Never use cables that are visibly damaged or that may be
suspected of being damaged.
Minimise conductivity, avoiding surfaces in contact with wa-
ter. Hands and clothes have to be dry.
Do not use, install or store the system under wet or damp
conditions.

Mechanical
safety
•
Due to the weight of the battery modules (>100 kg), mechan-
ical means have to be employed to install them.
•
Do not stack SelectCell Ultimate modules more than 4 high.
•
•
Use only 600V insulated tools
If terminals are exposed during the sectioning process,
use 600V rated insulating gloves.
Use a face shield during the work.
Should it be necessary to perform an operation on a bat-
tery pack, place the modules on insulating matting.
Use insulating footwear.
To avoid possible short-circuiting, do not carry any con-
ductive device (e.g. pens, tape measures, etc.) during the
work.
Do not wear any metal, conductive or sharp edged
accessories.
2.5
User
requirements
In addition to personnel who work with the module, workplace
users should also implement safety measure by applying the
minimum provisions on the protection of the health and safety of
workers exposed to electrical risk in the workplace, refer to your
local jurisdiction.
Hazards related to electrical risk are specifically identified dur-
ing the work process with this equipment. This does not exclude
the possible existence of other risks present during handling and
use, such as overexertion, posture, or other measures against
health risks. Operators shall receive the necessary training,
sufficient to be able to prevent and avoid any risks arising from
use of the equipment.
By design the equipment protects against these risks under
normal operating conditions, however, it is with operations that
differ from normal ones (installation, maintenance, ...) where
special precautions have to be taken.
Particular care should be taken when handling modules, due
to their weight. Respect guidelines according to current regu-
lations regarding ergonomics in the. Use appropriate handling
equipment.
