Precautions
Power Supplies
The power supply circuit of the H3CT uses the capacitor drop meth-
od. This circuit should be used with a commercial sine-wave fre-
quency. The internal circuit may be damaged if a power supply with
higher frequency (i.e., inverter power supply) is used.
Environment
When using the Timer in an area with excess electronic noise, sepa-
rate the Timer, wiring, and the equipment which generates the input
signals as far as possible from the noise sources. It is also recom-
mended to shield the input signal wiring to prevent electronic inter-
ference.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions can damage the outer casing of the Timer.
Others
If the Timer is mounted on a control board, dismount the timer from
the control board or short-circuit the circuitry of the power board be-
fore carrying out a voltage withstand test between the electric cir-
cuitry and non current-carrying metal part of the Timer, in order to
prevent the internal circuitry of the Timer from damage.
