4.1 Special conditions for use in Zone 0 areas
Temperature measurement using the Ex-MX4 BT is allowed within Zone 0 only if the
following conditions are met:
1. The Ex-MX4 BT temperature measuring device must not be brought into Zone 0.
2. Absolutely ensure that the device does not fall into Zone 0, even by mistake. To
ensure this, the device‘s carrying sling must also be attached securely to the
operator’s belt or to a belt loop. The length of the carrying sling should be measu-
red such that the Ex-MX4 BT is still at a distance of 50 cm from the boundary area
of Zone 0 when it hangs freely on the carrying sling.
Only carrying slings approved by ecom instruments GmbH must be used.
