Chapter 4 Installation and Removal
Turn the power off and wait for at least ten minutes, before starting installation. Further, check that the LED
monitor and charge lamp are unlit, and check the DC link circuit voltage between the P (+) and N (-) terminals
to be lower than 25 VDC.
Otherwise, electric shock could occur.
• Do not use the product that is damaged or lacking parts.
Doing so could cause a fire, an accident, or injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter and the interface card.
Otherwise, a fire or an accident might result.
• Incorrect handling in installation/removal jobs could cause a failure.
A failure might result.
4.1 Installing the Interface Card
Before mounting the interface card, perform the wiring for the main circuit terminals and control circuit
terminals.
(1) Remove the front cover from the inverter and expose the control printed circuit board (control PCB). The
interface card can be connected to the option connection ports on the inverter's control PCB.
Check the user's manual of an inverter about the connection port of the interface card.
To remove the front cover, refer to "wiring" in the Inverter Instruction Manual.
(2) Insert connector CN1 on the back of the interface card (Figure 2-2) into the option connection ports on the
inverter's control PCB. Then tighten the two screws that come with the card. (Figure 4-2)
Check that the positioning cutout (shown in Figure 4-1) is fitted on the tab (
c
in Figure 4-1) and
connector CN1 is fully inserted ( d in Figure 4-1). Figure 4-2 shows the interface card correctly
mounted.
(3) Perform wiring on the interface card.
For wiring instructions, see Chapter 5.
(4) Put the front cover back into place.
To put back the front cover, refer to "wiring" in the Inverter Instruction Manual.
