Dräger X-am 2500 7
2.3.3 Safety Instructions
Only the functions of the part of the equipment used to measure
flammable gases are measured as part of the CSA approval.
WARNING
Do not replace or charge batteries in potentially
explosive areas. Explosion hazard!
Charge the NiMH power pack T4 (type HBT 0000) or
T4 HC (type HBT 0100) with the associated Dräger
charger. Charge NiMH single cells for ABT 0100
battery holder in accordance with the manufacturer's
specifications. Ambient temperature during the
charging process: 0 to +40 °C.
To reduce the danger of explosion, do not mix new
batteries with old batteries and do not mix batteries
made by different manufacturers.
Always disconnect the instrument from the power pack
before carrying out any maintenance operations.
Substitution of components may impair intrinsic safety.
Only use power packs ABT 0100 (order no. 83 22 237),
HBT 0000 (order no. 83 18 704) or HBT 0100 (order no.
83 22 244). See marking on power pack for approved
batteries and related temperature classes.
Not tested in an oxygen-enriched atmosphere
(>21 % O
2
).
High off-scale readings may indicate an explosive
concentration.
CAUTION
Re. CSA approval:
Before use each day, test the sensitivity using a known
concentration of the gas being measured,
corresponding to between 25 and 50 % of the
maximum concentration. The accuracy must be in
a range of 0 to +20 % of the actual value. Correct the
accuracy via adjustment if necessary.
