General information and warnings
1.2.1 Safe handling of equipment with batteries
1.2.2 Wet conditions
Under wet conditions, the plug must be connected to the final branch circuit via an
appropriate socket / receptacle designed for washdown use.
Installations within the USA should use a cover that meets NEMA 3R specifications
as required by the National Electrical Code under section 410-57. This allows the unit
to be plugged in with a rain tight cover fitted over the plug.
Installations within Europe must use a socket which provides a minimum of IP56
protection to the plug / cable assembly. Care must be taken to make sure that the
degree of protection provided by the socket is suitable for the environment.
1.3 Routine maintenance
Always isolate the indicator from the power supply before starting any routine
maintenance to avoid the possibility of electric shock.
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer. Dispose
of used batteries according to the manufacturer’s instructions.
ATTENTION: Il y a danger d'explosion s'il y a remplacement incorrect de la
batterie, remplacer uniquement avec une batterie du même type ou d'un type
équivalent recommandé par le constructeur. Mettre au rebut les batteries
usagées conformément aux instructions du fabricant.
IMPORTANT: This equipment must be routinely checked for proper operation
and calibration.
Application and usage will determine the frequency of calibration required for
safe operation.
