14. Précautions lorsque vous travaillez avec des piles.
–
Les piles contiennent très corrosif acide sulfurique dilué comme électrolyte. Des précautions doivent être
prises pour empêcher tout contact avec la peau, les yeux ou les vêtements. Porter des lunettes de protection
–
Les batteries produisent de l’hydrogène et de l’oxygène lors de la charge résultant de l’évolution du mélange
de gaz explosif. Il faut prendre soin de ventiler la zone de la batterie et de suivre les recommandations du
fabricant de la batterie.
–
Ne jamais fumer ou permettre une étincelle ou une flamme près des batteries.
–
Faites preuve de prudence afin de réduire le risque de chute d’un outil métallique sur la batterie. Il pourrait
provoquer un court-circuit ou la batterie ou d’autres pièces électriques et pourrait causer une explosion.
Toujours utiliser des outils isolés
–
Retirez les articles métalliques tels que des bagues, des bracelets et des montres lorsque vous travaillez avec
des batteries. Les batteries peuvent produire un court-circuit suffisamment élevé pour souder une bague ou
autre métal et ainsi causer de graves brûlures.
–
Si vous devez retirer la batterie, retirez toujours la borne de terre de la batterie. Assurez-vous que tous les
accessoires sont hors de sorte que vous ne causent pas une étincelle.
1.2 DeFinitionS
The following definitions are used in this manual for explaining various electrical concepts,
specifications and operations:
Peak Value: It is the maximum value of electrical parameter like voltage / current.
rMS (root Mean Square) Value: It is a statistical average value of a quantity that varies in
value with respect to time. for example, a pure sine wave that alternates between peak values
of Positive 169.68V and Negative 169.68V has an rMS value of 120 VAC. Also, for a pure sine
wave, the rMS value = Peak value ÷ 1.414.
Voltage (V), Volts:
It is denoted by “V” and the unit is “Volts”. It is the electrical force that
drives electrical current (I) when connected to a load. It can be DC (Direct Current – flow in
one direction only) or AC (Alternating Current – direction of flow changes periodically). The AC
value shown in the specifications is the rMS (root Mean Square) value.
Current (i), Amps, A: It is denoted by “I” and the unit is Amperes – shown as “A”. It is the
flow of electrons through a conductor when a voltage (V) is applied across it.
Frequency (F), hz:
It is a measure of the number of occurrences of a repeating event per unit
time. for example, cycles per second (or Hertz) in a sinusoidal voltage.
efficiency, (
η
): This is the ratio of Power Output ÷ Power Input.
Phase Angle, (
φ
):
It is denoted by “
φ
” and specifies the angle in degrees by which the current
vector leads or lags the voltage vector in a sinusoidal voltage. In a purely inductive load, the
current vector lags the voltage vector by Phase Angle (
φ
) = 90°. In a purely capacitive load, the
current vector leads the voltage vector by Phase Angle, (
φ
) = 90°. In a purely resistive load, the
current vector is in phase with the voltage vector and hence, the Phase Angle, (
φ
) = 0°. In a load
consisting of a combination of resistances, inductances and capacitances, the Phase Angle (
φ
) of
the net current vector will be > 0° < 90° and may lag or lead the voltage vector.
resistance (r), ohm, Ω:
It is the property of a conductor that opposes the flow of current
when a voltage is applied across it. In a resistance, the current is in phase with the voltage. It is
denoted by “r” and its unit is “Ohm” - also denoted as “Ω”.
