H3DT Safety Precautions Refer to Safety Precautions for All Timers. Format of Warning Indications CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Precautions for Safe Use Indicates supplementary comments on what to do or avoid doing, to use the product safety.
H3DT • The Timer may not operate properly in locations that are subject to sulfide gas, such as in sewers or incinerators. Products that are suitable for operation in sulfide gas are not available for OMRON Timers or general control devices. Seal the Timer to isolate it from sulfide gas. If the Timer cannot be sealed, OMRON can make special products with resistance to sulfide gas for some Timers. Ask your OMRON representative for details.
H3DT • If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not be different in phase or the terminals will be short-circuited to one another. Always use the same power supply phases. Wiring 1.
H3DT 2. Removing Wires from the Push-In Plus Terminal Block Recommended Flat-blade Screwdriver Use the following procedure to remove wires from the terminal block. The same method is used to remove stranded wires, solid wires, and ferrules. 1. Hold a flat-blade screwdriver at an angle and insert it into the release hole. 2. With the flat-blade screwdriver still inserted into the release hole, remove the wire from the terminal insertion hole. 3. Remove the flat-blade screwdriver from the release hole.
H3DT Other Precautions • If the Timer is mounted on a control panel, dismount the Timer from the control panel before carrying out a voltage withstand test between the electric circuits and non-current-carrying metal parts of the Timer. (Otherwise, the internal circuits of the Timer may be damaged.) • The H3DK-H uses a latching relay for the output. Shock, such as dropping the H3DK-H during shipment or handling, can cause the output contacts to reverse to the neutral position.
