Special Condition for Safe Use
1. The temperature class depends on ambient temperature range as follows:
2. Safety Parameters:
3. The cable entry of transmitter should be protected to ensure the degree of protection of
the enclosure IP 20 (GB4208-1993) at least.
4. The cables between transmitter and associated apparatus should be shielded cables
(the cables must have insulated shield). The cable core section area should be more
than 0.5 mm
2
. The shield has to be grounded reliably. The wiring has to not be affected
by electromagnetic disturbance.
5. COMM interface is forbidden to use in hazardous location.
