Precautions
Mounting
When two or more timers are to be mounted in line, provide a dis -
tance of more than 5 mm between the two adjacent timers.
When two or more timers mounted in line are to be continuously en -
ergized
at the same time after the set time has elapsed, be sure to
limit the carry current to less than 1 A.
When using the timers at an ambient temperature of more than
40°C,
be sure to reset the timers immediately after the set time has
elapsed.
Wiring
When wiring, employ a multi-core cable having a finished outer di -
ameter of less than 10.5 mm, or insulated (twisted) wires with less
than a 3 mm outer diameter .
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. T o convert grams into ounces, multiply by 0.03527.
