3-4. Connecting the DC power
supply input terminals
The DC power supply input voltage should be 24 V ±10%.
Use a power supply cord that is 0.517 to 2.081 mm
2
(20 to
14 AWG).
When connecting to the terminal bank, use a solderless termi-
nal (M3, width of 6 mm or less).

ATTENTION
o
If using the unit as a CE compliant product, the power cord
must be no more than 3m long.
o
Allow the unit to warm up for at least five minutes after
supplying power to it.
o
The recommended tightening torque for terminals is 0.5 N·m
(5.1 kgf-cm).
V
Always attach the cover to the power supply input
terminal bank. Failure to do so could result in fire,
electric shock or malfunction.
V
Use a power supply that conforms to a limited energy
circuit as specified in IEC61010-1. Failure to do so
could cause fire or other hazards.
