Installing the Test System
Connecting the power cable
Connect the power cable to the control power supply input (AC INPUT) terminal on the rear
panel of the product.
1
Check that the AC power line meets the nominal input rating of the prod-
uct.
This product can be used with an input voltage ranging from 100 V to 240 V.
The supported frequencies are 50 Hz and 60 Hz.
2
Check that the POWER switch is turned off ( ).
3
Remove the terminal cover from the lower part of the rear panel.
For instructions on how to remove the terminal cover, see steps 3 and 4 in
4
Connect the power cable to the control power supply input (AC INPUT)
terminal on the rear panel.
If you want to use a power cable other than the supplied or optional cable, use a
cable with crimping terminals that match the M4 screws of the AC INPUT terminal.
5
Turn off the switchboard’s circuit breaker.
6
Connect the power cable to the switchboard.
Use crimping terminals that match the size of the screws of the switchboard terminals.
7
Attach the terminal block cover that you removed in step 3.
WARNING
Risk of electric shock.
• This product conforms to IEC Safety Class I (equipment that has a protective con-
ductor terminal). Be sure to earth ground the product to prevent electric shock.
• Connect the protective conductor terminal to earth ground.
• Have a qualified engineer connect the power cable to the switchboard.
• For the connected switchboard, select a circuit breaker that has a cut-off current
that can handle the maximum input current of the product
CAUTION
• If the voltage distortion of the AC power line is large, the product may malfunction.
The product cannot be connected to a generator or the like.
• Use the AC line for the input power supply. Do not supply power from the output of the AC
power supplies that are connected to this product.
• Inside the product, protective circuits are connected to match the input terminal. Connect
the cable correctly.
• The control power cable supplied with the product or an optional heavy PVC jacketed
three-core control power cable (AC5.5-3P3M-M4C) can be used.
