WARNING
This product contains powerful battery packs (NiMH) and is supplied by
multiple hazardous electrical sources. Beware of stored and residual energies.
Obey local regulations for live working when the casing/door is open. Wear
electrically insulated gloves when handling battery packs. Battery surfaces
may carry hazardous voltage due to lowered insulation resistance. Do not place
battery packs on conductive surfaces. Risk for electric shock and arcing if
the product is used incorrectly. The battery packs cannot be turned off
electrically.
Please note:
- Work only with one battery pack terminal at a time.
- A rupture disc may release electrolytes during abnormal use. We, therefore, recommend wearing safety glasses.
Risk for electrical hazards if the product is exposed to rain or moisture. Do not operate the product with suspected failures. If you suspect that the product is damaged, have it inspected by qualified service personnel. Never install a damaged battery pack or a damaged insulation tray. Do not block or cover the rupture disc outlet on the battery pack. If a fire occurs, it can be extinguished by using CO2. Ensure that fire extinguishers are available.
CAUTION
If a battery pack is damaged mechanically, the following may occur:
-
High heat generation on the surface of the battery cells.
-
Electrolyte may escape.
-
Eventual smoke from the battery packs can irritate the skin, eyes and respiratory system. Therefore, follow these guidelines
-
Do not open the battery packs.
-
Do not modify or mechanically damage the battery packs.
-
Operate the Nilar Home Box only within the allowed
operating range. -
Do not short‐circuit the baery packs.
-
Do not continue to use the battery packs atier identified as faulty.
It is required that a smoke alarm, preferably with connected surveillance function, is installed in close and strategical connection with the installation of the product. Furthermore, the installation of a gas alarm that warns in case of high levels of hydrogen is recommended. Always install the product in a well‐ventlated location. To avoid potential hazards, use this product only as specified. Do not operate the product with covers removed. If covers are removed during e.g. repair, do not touch any exposedconnections. The product shall not be exposed to liquids (not even dripping or splashing) and objects filled with liquids must not be placed on or close to the product. Remove personal metal items such as rings, bracelets, necklaces, and watches when physically handling the product since it can result in a short‐circuit current causing severe burn. Keep product surfaces clean and dry.
