Warning! / Achtung! / Attention! / Advertencia! / 警告!
. Do not connect directly to AC/DC power source. Connect valve
to appropriate controller/driver only. Do not operate valve while
assembling or disassembling
. Bitte den ETS nicht direkt mit einer Spannungsquelle
(Gleich- oder Wechselstrom) verbinden. Schließen Sie das Ventil
nur an geeignete Regler/Steuergeräte an. Ventil bitte nicht in
zerlegtem Zustand ansteuern.
. Ne pas raccorder directement le moteur à une alimentation
AC / DC. Raccorder la vanne au régulateur approprié.
Ne pas actionner la vanne pendant le montage ou le démontage.
. No aplicar tensión directamente a la válvula. Conectar la válvula
a un controlador/driver adecuado. No haga funcionar la válvula
durante el montaje o desmontaje.
. 请仅将阀门连接于合适的控制器/驱动器，勿直接与交流或直 流
电源连接。在安装和拆卸阀门时请勿操作电子膨胀阀。
Special note for R1234ze(E), R1234yf and R516A:
Ignition risk is evaluated in accordance to ISO5149/EN378 and IEC60335-2-40.
- Do not use valve outside of the stated temperature limits.
- Do not unplug when energized
- Must be installed in a suitable end use enclosure to protect the valve electrical
plug against moisture, dust, dirt and impact.
- For countries where safety standards are not an indispensable part of the
safety system Danfoss recommend the installer to get a third party approval of
the system containing flammable refrigerant.
