Step 1. Allow more than 10 seconds to elapse after removing the power cords from the VX-3000DS' rear-
mounted AC inlets (IN1 and IN2).
Step 2. Insert the positive battery cable into the VX-3000DS' rear-mounted BATTERY POWER IN positive
terminal from the bottom side of the connector, then tighten the terminal screw with a flat screwdriver.
Note
Never connect the negative cable first to avoid battery short-circuit that occurs if the positive cable
should contact the unit chassis or equipment rack.
Step 3. Connect the negative battery cable to the negative terminal in the same manner as Step 2.

• Total resistance of the battery connection path should be less than 4 mΩ, which includes resistance of all of
wire, terminal, fuse, and terminal points.
For reference, refer to each resistance as follows.
Resistance of terminal, fuse (if provided): 1 – 2 mΩ
Resistance of terminal point:
0.1 – 0.5 mΩ
• Tighten the bolts, nuts, and screws of the unit's battery connection terminals and battery terminals with the
torque as shown below.
