WARNING
Be sure to install a breaker with the specifi ed capacity.
Regulation of cables and breaker differs from each locality, refer in accordance with local rules.
Select the correct capacity of the power supply according to the load (total current value of the connected units).
Voltage rating 1Ø 208/230V (60Hz)
Operating range 187-264V
Cable Cable size *1) Remarks
Power supply cable 14AWG 2 cable + Ground, 1 Ø 208/230V
Connection cable 14AWG 3 cable + Ground, 1 Ø 208/230V
1) Selected sample: Select the correct cable type and size according to the country or region’s regulations.
Max. wire length: Set a length so that the voltage drop is less than 2%. Increase the wire diameter when the wire length is long.
Breaker Specifi cation *2)
Circuit breaker (MOCP) *4) Current : 15 (A)
Earth leakage breaker Leakage current : 30mA 0.1sec or less *3)
2) Select the appropriate breaker of the described specifi cation according to the national or regional standards.
3) Select the breaker that enough load current can pass through it.
4) MOCP: Maximum Over Current Protection
HOW TO CONNECT WIRING TO THE TERMINALS FOR STAND WIRING.
(1) Use crimp-type terminals with insulating sleeves as
shown in the fi gure below to connect to the terminal block.
(2) Securely crimp the crimp-type terminals to the wires
using an appropriate tool so that the wires do not come
loose.
(3)
Use the specifi ed wires, connect them securely, and fasten
them so that there is no stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal
screws. Do not use a screwdriver that is too small,
otherwise, the screw heads may be damaged and
prevent the screws from being properly tightened.
(5) Do not tighten the terminal screws too much, otherwise,
the screws may break.
(6) See the table below for the terminal screw tightening
torques.
WARNING
Use crimp-type terminals and tighten the terminal screws to the specifi ed torques, otherwise, abnormal overheating may
be produced and possibly cause heavy damage inside the unit.
