Dc Connection Precautions - TecMate Optimate TM270 Mode D'emploi

c) Clean battery terminals.Be careful to keep corrosion from coming in contact with eyes.
d) Study all battery manufacturer's specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.
e) Determine voltage of battery by referring to vehicle or other user's manual and BEFORE MAKING THE BATTERY CONNECTIONS, MAKE SURE THAT THE
VOLTAGE OF THE BATTERY YOU ARE GOING TO CHARGE MATCHES THE OUTPUT VOLTAGE OF THE CHARGER.
13. CHARGER LOCATION.
a) Locate charger as far away from battery as DC cables permit.
b) Never place charger directly above batterv being charged; gases from battery will corrode and damage the charger. c) Never allow battery acid to drip on charger
when reading gravity or filling battery. Do not operate charger in a closed-in area or restrict ventilation in any way.
d) Do not set a battery on top of charger. IMPORTANT : Place charger on a hard flat surface or mount onto a vertical surface. Do not place on plastic, leather
or textile surface.

14. DC CONNECTION PRECAUTIONS

Connect and disconnect DC output clips only after setting any charger switches to off position and removing
a)
AC cord from electric outlet.
automatic charging programme will just reset to «start».
b) Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through 16(d).
NOTE : This battery charger has an automatic safety feature that will prevent it from operating if the battery has
been inversely connected.
reconnect correctly according to the instructions below.
15. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR A
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY :
a) Position AC and DC cords so as to reduce risk of damage by hood, door or moving engine part.
b) Stay clear of fan -blades, belts,pulleys,and other parts that can cause injury to persons.
c) Check polarity of battery posts.POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post.
d) Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles),see (e). If positive
post is grounded to the chassis,see (f).
e) For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, + ) ungrounded post of battery. Connect NEGATIVE
(BLACK) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a
heavy gage metal part of the frame or engine block.
f) For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE (NEG. N , -) ungrounded post of battery. Connect
POSITIVE (RED) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect
to a heavy gage metal part of the frame or engine block.
g) When disconnecting charger, turn switches to off, disconnect AC cord,remove clip from vehicle chassis,and then remove clip from battery terminal.
h) See operating instructions for length of charge information.
16. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY
MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY :
a) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG,N, -) post.
This battery charger has an automatic safety feature that will prevent it from operating if the battery has been
b)
inversely connected. The charger does allow charge current unless a voltage of at least 0.5V is sensed.
c) Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
d) Connect NEGATIVE (BLACK) charger clip to NEGATIVE (NEG, N, -) battery post of the battery.
e) Do not face battery when making final connection.
f) When disconnecting charger, always do so in reverse sequence of connecting procedure & break first connection while as far away from battery as
practical.
g) A marine (boat) battery must be removed & charged on shore. To charge it on board requires equipment specially designed for marine use.

Never allow clips to touch each other, however should this happen no damage will result to the charger circuit & the
Set charger switches to off position and/or remove AC cord from electrical outlet, disconnect the battery clips, then
