Connection of connecting plate
Install batteries with the correct polarity (
＋
,
－
). Installing batteries with the polarity reversed can result in
fire or damage to the batteries or chargers.
Do not tighten the bolts and nuts to any torque other than the stipulated values. Tightening to other torque
can cause damage to the terminals through sparking or deformation.
Avoid using a wire brush or other hard tools to polish the battery terminal and connecting plate surfaces.
Otherwise the lead plating can peel off, resulting in corrosion.
Lightly apply the enclosed lead acid battery use anticorrosion agent (white vaseline, etc.) over the entire
battery terminal area, and then attach the connecting conductor with a bolt and nut. After attaching, lightly
apply the enclosed lead acid battery use anticorrosion agent to the area around where the bolt and nut
and connecting conductor are fastened. Failure to apply the anticorrosion agent can result in the
generation of a high-resistance corrosion layer.
Polish surfaces of all battery terminals (surfaces in contact with the connecting plate) using a brass brush
or the like.
Polish the conductive connecting surfaces of the connecting plates (the interfaces between the terminals
and the connecting plates) using a brass brush or the like.
Apply a thin coat of the lead acid battery anticorrosion agent (provided with the product) on the polished
conductive contact surfaces of the connecting plates and battery terminals.
Sequentially connect the connecting plates by using M10 bolts (with a flat washer and a spring washer)
according to the working drawing.
Tighten all the connecting bolts to 17.2±2.5 N
･
m (175±25 kgf
･
cm).
Finally, check that all the bolts have been tightened and apply a thin coat of the lead acid battery
anticorrosion agent (provided with the product) around the tightened parts of the bolts, nuts and connecting
conductors.
Do not allow coated wire or sheets containing soft vinyl chloride or other plastic
to touch the container or lid. In addition, benzene, thinner, gasoline or other organic
solvents or detergents should also not be allowed to come into contact with the
container or lid. Such contact can result in container or lid breaking or cracks,
becoming the cause of electrolyte leakage.
⑤
Installing the connecting plate covers
Install the intermediate connecting plate covers, the inter-row connecting plate covers and the terminal
connecting plate covers from the front side.
(2) Installation (In case that the batteries are installed into the unit on the site )
①
Installing the channel bases
Carry out in the same way as described in the work of the Section 4.2 ,(1) ,
①
( "Installing the channel
base").
②
Installing the unit on the first stage
Slowly lower the unit while aligning the unit mounting holes with the channel base mounting holes.
Adjust the unit in the proper position. Insert the unit fixing bolts (M12×35 with two plain washers) from
below the channel bases through the unit mounting holes, and temporarily secure the bolts using the nuts
(with two plain washers). (See Figure 3.)
