Note: Do not select automatic reset if safety of the system requires
manual reset.
Note: Selected reset configuration may be protected against unauthorized
actions applying a seal.

IMPORTANT NOTICE
Safety requirements
- KP pressure switches shall only be employed in the units/systems which comply with the requirements for charge limits and requirements for avoiding ignition sources of IEC 60335-2-24, IEC 60335-2-40, IEC 60335-2-89, ISO 5149, EN378-1 or equivalent.
- Applying the overload on the KPs must be prevented. If by any chance it was damaged, the system/unit shall be stopped and KP shall be replaced as necessary.
- Electrostatic discharge protection and Electrical leakage protection shall be surely implemented by grounding or other measures.
- Only trained personnel are authorized to handle flammable refrigerant systems and may do the installation, maintenance, and exchange of the switch by using appropriate tools.
- It is recommended to regularly check the function of KP switch.
- KP pressure switches must be installed in an area with a low risk of mechanical damage.
- Corrosion protection of KP pressure switches must be taken into account when used in a corrosive environment.
- Cables shall not be in contact with sharp edges. The cables shall be connected with adequate stress relief in order to prevent pulling forces can be carried through the cable to the terminal.
- In the event of pressure pulsation in the system, where the switch is connected, these must be effectively dumped to prevent failure of the bellows. The cycle frequency of the KP switch shall be kept as low as possible.
- The KP switches shall not be installed in places where a high level of vibration is present.
