4.2 Installation and Connecting
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.
(1) Installation (In case that the batteries have already been installed into the unit)
①
Installing the channel bases
Temporarily secure the channel bases to the floor by using the chemical anchor bolts (provided with the
product) according to the attached working drawing.
Level all the channel bases within ±1 mm by using the leveling plate.
Adjust the span of the unit battery mounting holes.
Tighten the anchor bolts to the torque specified in the table below.

Note: These values are the specified torques after hardening.
When using any anchor bolts other than the anchor bolts provided with the product, tighten them to the
torque specified in the instruction manual for the anchor bolts.
②
Installing the batteries on the first stage
Use torque wrenches, spanners and other metal tools insulated with vinyl
tape or the like. The use of non-insulated tools can result in a short circuit
leading to burn injuries and the explosion of batteries or other damage to batteries.
Do not topple or strike single batteries and unit batteries. The batteries can break
or cause injury.
Mount the M12 eyebolt nuts to the channel at the upper edge of a unit battery and lift the battery with a
lifter or the like to put the battery on its side. (See Figure 1.)
