● Wiring
The H3DK-H acts like a high-impedance circuit. Therefore, the
Timer may not reset if it is influenced by inductive voltage. To
eliminate inductive voltage, the wires connected to the Timer
must be as short as possible and should not be installed parallel
to power lines. If the Timer is influenced by inductive voltage that
is 30% or more of the rated voltage, connect a CR filter with a
capacitance of approximately 0.1 µF and a resistance of approx-
imately 120 Ω or a bleeder resistor between the power supply
terminals.
If there is any residual voltage due to current leakage, connect a
bleeder resistor between the power supply terminals.

Notice to Users of the H3DK in the USA and Canada
Please use the following installation information instead of the
general information in this document in order to use the product
under certified conditions of UL and CSA when the product is
installed in the USA or Canada. These conditions are required by
NFPA 70, National Electrical Code in the USA and the Canadian
Electrical Code, Part I in Canada and may vary from information
given in this document.
