Electrical installation

6. Screw the remote antenna in at the end of the antenna cable and tighten it
by hand.
5.4 Installing the EC sensor
If the gas detector is already switched on and an existing sensor is changed,
see "Replace sensor", page 49.
For specific information, refer to the sensor data sheet.
Prerequisites:
– The gas detector is installed.
Install sensor:
1. Loosen the set screw (Fig. B 2).
2. Unscrew bayonet ring (Fig. B 3).
3. Remove the dummy disk.
4. Insert the sensor (Fig. B 4) Into the opening so that the Dräger logo is
aligned with the marking on the housing (Fig. B 5).
5. Secure the sensor with the bayonet ring.
6. Tighten the set screw. Required for installation in Zone 22.
7. If necessary, attach the tag supplied with the sensor to the gas detector.

WARNING
Risk of explosion!
The simultaneous connection of wired power supply and battery endangers the
intrinsic safety and leads to the expiration of the explosion protection approval.
► Do not connect the wired power supply and battery at the same time.

6.1
Risk of explosion!
If the gas detector is opened in a potentially explosive dust atmosphere, an
explosion may occur.
► Do not open the gas detector in dust explosion-hazard areas. Alternatively,
supply unit of protection Class II or NEC Class II instead.

WARNING
declassify the dust explosion-hazard area beforehand.
Do not operate the gas detector with a DC power supply, but use a power
Explosion-hazard areas: The power supply is provided via a safety barrier,
which ensures intrinsic safety of the gas detector.
Observe maximum capacity and inductance of the cable for the connection
to the safety barrier.
Dräger recommends the following safety barriers: Pepperl + Fuchs
SMART Transmitter Power Supply KFD2-STC5-Ex1 or KCD2-STC-Ex1.
Non-hazardous areas: cable gland M25 x 1.5
Explosion-hazard areas: Ex e cable gland M25 x 1.5
Non-hazardous areas: See A and D
Explosion-hazard areas: See A and E (Used with safety barrier)

a. Loosen the set screw (Fig. A 14).
b. Turn the housing cover (Fig. A 1) approx. 20° counterclockwise and
remove it.
c. Pull out the battery box (Fig. A 2).
