al blocks are not equipped with built-in fuses. In order to prevent breakdown of circuits caused by
ort-circuit, provide a fuse of 5 to 10 A for every four points.

Connect a noise suppression diode to a DC inductive load in parallel.
If the diode is not connected, the life time of the contact becomes
considerably shorter.
Select a noise suppression diode whose reverse withstand voltage is
5 to 10 times or more the load voltage and whose current in the for-
ward direction is not less than the load current.

When a surge absorber is connected to an AC inductive load in paral-
lel, noise generation is reduced.
0.1 µF capacitor + 100 to 120 Ω resistor
andard life time of contactors and solenoid valves against AC inductive load is 500,000 times of
on against 35 VA.
le below shows the guideline of the life time of relays based on the result of the life time test per-
in our company.
mind that the life time of a relay contact becomes considerably shorter even in the condition below
