Correct Use The operating voltage will increase when using the H3YN continuously in any place where the ambient temperature is in a range of 45C to 50C. Supply 90% to 110% of the rated voltages (at 12 VDC: 95% to 110%). Do not leave the H3YN in time-up condition for a long period of time (for example, more than one month in any place where the ambient temperature is high), otherwise the internal parts (aluminum electrolytic capacitor) may become damaged. Therefore, the use of the H3YN with a relay as shown in the following circuit diagram is recommended to extend the service life of the H3YN. Be careful not to apply any voltage to the terminal screws on the back of the Timer. Mount the product so that the screws will not come in contact with the panel or metal parts. Do not use the H3YN in places where there is excessive dust, corrosive gas, or direct sunlight. Do not mount more than one H3YN closely together, otherwise the internal parts may become damaged. Make sure that there is a space of 5 mm or more between any H3YN models next to each other to allow heat radiation. The internal parts may become damaged if a supply voltage other than the rated ones is imposed on the H3YN. In order to conform to UL and CSA requirements when using the H3YN-4/-41 or H3YN-4-Z/-41-Z, connect the Unit so that output contacts (contacts of different poles) have the same electric potential. X2/b T/a T X1/a X1 X1/a In cases such as PLC input where the load is extremely small for the control output of a timer containing a power relay (using other than gold-plated contacts), reliability can be increased by using contacts of the same poles (e.g., the H3Y-2) in parallel. X2 X : Auxiliary relay such as MY Relay The H3YN must be disconnected from the Socket when setting the DIP switch, otherwise the user may touch a terminal imposed with a high voltage and get an electric shock. Do not connect the H3YN as shown in the following circuit diagram on the right hand side, otherwise the H3YN's internal contacts different from each other in polarity may become short-circuited. Correct Precautions for EN61812-1 Conformance The H3YN as a built-in timer conforms to EN61812-1 provided that the following conditions are satisfied. Handling Incorrect L2 Do not touch the DIP switch while power is supplied to the H3YN. Before dismounting the H3YN from the Socket, make sure that no voltage is imposed on any terminal of the H3YN. L1 L2 L1 Use the following safety circuit when building a self-holding or selfresetting circuit with the H3YN and an auxiliary relay, such as an MY Relay, in combination. The applicable Socket is the PYF@A. Only basic insulation is ensured between the Y92H-3 Hold-down Clips and H3YN internal circuits. Do not allow the Y92H-3 Hold-down Clips to contact other parts. The insulation test voltage between different pole contacts for the 4pole model is the impulse voltage of 2.95 kV. Wiring The power supply for the H3YN must be protected with equipment such as a breaker approved by VDE. : Auxiliary relay such as MY Relay In the case of the above circuit, the H3YN will be in pulse operation. Therefore, if the circuit shown on page 5 is used, no auxiliary relay will be required. Do not set to the minimum setting in the flicker modes, otherwise the contact may become damaged. Basic insulation is ensured between the H3YN's operating circuit and control output. Basic insulation: Overvoltage category II, pollution degree 1 (H3YN-4/-41, H3YN-4-Z/41-Z), pollution degree 2 (H3YN-2/-21) (with a clearance of 1.5 mm and a creepage distance of 2.5 mm at 240 VAC) ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
