A DC power supply must be connected to the power input terminals as designated according to the polarity of the terminals. A DC power supply can be connected if its ripple factor is 20% or less and the mean voltage is within the rated operating voltage range of the Timer. Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value at once or the Timer may not be reset or a timer error could result. ror the power supply of an input device, use an isolating transform- er, of which the primary and secondary windings are mutually iso- lated and the secondary winding is not grounded.

Do not attempt to connect any input terminal to any terminal other than the common terminal or to apply voltage across other than the specified input and common terminals or the internal cir- cuits of the Timer may be damaged. a* Input contact 7 Power supply Pa ac AC or OC H3CR 5, 6,7 * G,S,R Input terminal T 10 \ i | { , *Power supply terminal 2 is a common terminal for the input signals (G, S, R) to the Timer. Never use terminal 10 as the common terminal for this purpose, otherwise the internal circuit of the Timer may be damaged. **Do not connect a relay or any other load between these two points, otherwise the internal circuit of the Timer may be damaged due to the high-tension voitage applied to the input terminals. omRON H3CR-A When connecting a relay or a transistor as an external signal input device, pay attention to the following points to prevent short-circuit. ing due to a sneak current to the transformerless power supply, 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 willnot be different in phase or the terminals will be short-circuited to one : another (refer to the figures below). e | Contact or transistor for H&CR series timer external input signal i % HO oe ww : : 2 input . i ets, ~ i; terminal ; ~~} Power supply ~ A 2 ad Incorrect i Pood Short-circuit | : a : : current } o | | | i | > Input | i i |; terminal | L pov , Cy by | ~ | Input f A 1 | terminal | [~) Power supply v | i a et Ot ee ee Correct L | ) Input oO ; , terminal i yp 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. a Others * If the Timer is mounted on a control board, dismount the timer from the control board or short-circuit the circuitry of the powerboardbe- _. 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.
