Dc Connection Precautions - TecMate Optimate TM270 Modo De Empleo

Make sure all accessories in the vehicle are off, so as not to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged. Gas can be
forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.
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

a) Connect and disconnect DC output clips only after removing AC cord from electric outlet. Never allow clips to touch each
other, however should this happen no damage will result to the charger circuit & the 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.
Remove AC cord from electrical outlet, disconnect the battery clips, then 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. b) This battery charger has an automatic safety feature that will prevent it from operating if the battery has
been 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.
