Anv\u00e4ndning av uppm\u00e4rksamhet:<\/strong><\/p>\n

1. Jordningsbanan ska vara s\u00e5 kort som m\u00f6jligt och l\u00e4ngden b\u00f6r inte \u00f6verstiga 1,5 meter.<\/p>\n

2. Var uppm\u00e4rksam p\u00e5 kablar som kommer in och ut fr\u00e5n \u00f6versp\u00e4nningsskyddsanordningar vid installationen f\u00f6r att undvika \u00f6versp\u00e4nningskopplingar.<\/p>\n

3. Den skyddade utrustningen m\u00e5ste ha god jordning och jordningsimpedansen \u00e4r i enlighet med relevanta nationella standarder.<\/p>\n

4. Efter korrekt installation kan den fungera stadigt under l\u00e5ng tid. Om det visar sig att systemets \u00f6verf\u00f6ringsprestanda minskar eller signalen avbryts p\u00e5 grund av \u00f6versp\u00e4nningsskyddet, b\u00f6r det underh\u00e5llas eller bytas ut i tid.<\/p>\n
