Explosion hazardous areas
• VIBTOOL with intrinsic safety (VIB 2.700 EX) may only
be used with rechargeable batteries with the following
approval:
ZELM 05 ATEX 0243 U
• Rechargeable batteries must not be charged in explosive
environments! Only VIB 2.720 (EU), VIB 2.721 (USA) or
VIB 2.722 (UK) charging units may be used.
• The battery should not be removed under any circum-
stances! To replace a defective battery, VIBTOOL must
be sent back to the manufacturer.
• The accessories listed in the ‘Sensors & Accessories’
product catalog (VIB 9.663-1DG) are not allowed in
areas that contain inflammable dust!
• The VIBTOOL case (VIB 2.729) is not allowed in
explosion hazardous areas.
