Maintenance Features

The H5F Time Switch is designed for reliability and minimal maintenance, with clear guidelines for ensuring long-term performance.

Precautions for All Timers:

Terminal Wiring: Ensure terminals are wired correctly to prevent damage or malfunction. Do not connect more than two crimp terminals to each Time Switch terminal.
Power Supply:
- Ensure the fluctuation of the supply voltage is within the permissible range.
- Make sure that the voltage applied is within the specified range; otherwise, the internal elements of the Time Switch may be damaged.
- Supply the power supply voltage through a breaker, relay or switch in such a way that the voltage reaches a fixed value immediately.
- When power is turned ON, an inrush current or flow of a short-circuit current may occur. Make sure that the power supply can operate properly with a sufficient capacity and a breaker.
Operating Environment:
- Avoid locations where condensation may occur due to high humidity or where temperature changes are severe.
- Do not leave the Time Switch for long periods (e.g., one month or more) at a high temperature with output ON or in the ON state.
- Do not operate the Time Switch in locations where strong magnetic fields, static electricity, or noise are present.
- Do not use the Time Switch in locations exposed to dust, corrosive gases, or direct sunlight.
- If the ambient temperature of the H5F is stored at a temperature of less than -10°C, allow the H5F to stand at room temperature for at least 4 hours before use.
- This Time Switch is not waterproof or drip-proof. Do not use it in locations where water or oil may enter the Time Switch interior.
- Organic solvents (such as paint thinner) as well as strong acidic or basic solutions might damage the outer casing of the H5F.
Installation:
- Mounting the Time Switches side-by-side may reduce the life expectancy of the components.
- When using heaters, be sure to use a thermal switch for the load itself.
- When driving an inductive load (e.g., a coil), a surge voltage is generated when the contacts of a Time Switch (output) are switched, and this voltage may damage the power device connected to the Time Switch or the same line. Absorb the surge with a capacitor and resistor as shown in the wiring diagram.
Battery: The time and settings are backed up using a lithium battery. The display stays ON but the output turns OFF.
Disposal: Do not disassemble, repair, or modify the Time Switch. Doing so may result in electric shock, fire, or malfunction.

Precautions for EN61010-1 Conformance:

The H5F Time Switch conforms to EN61010-1, provided that the following conditions are satisfied:
- Basic insulation is provided between the power supply and output terminals of the H5F.
- Output terminals are connected to devices without exposed charged parts.
- Output terminals are connected to devices with basic insulation that is suitable for the maximum operating voltage.

Others:

None of the Time Switch components are user-replaceable, including the battery.

The H5F Time Switch is available in different mounting types:

H5F-B (Flush Mounting): Designed for flush mounting into a panel, providing a clean and integrated appearance.
H5F-FB (Surface Mounting): Suitable for surface mounting applications, offering easy installation on a flat surface.
H5F-KB (Surface/Track Mounting): Provides flexibility for both surface and DIN track mounting.

Accessories such as soft covers, hard covers, flush mounting adapters, mounting tracks, end plates, and spacers are available to facilitate installation and protection.
