FOR YOUR SAFETY
WARNING:
Risk of explosion from escaping gas
There is a risk of explosion due to escaping hot gases when the sender/receiver unit is
pulled out of the duct or the maximum process pressure is exceeded.
▸
Only fit or remove device components when the system is shut down.
▸
Observe the maximum permissible process pressure (
), safe operation of the measuring system is not possible when this value is
exceeded.
CAUTION:
Risk of explosion through incorrect or missing potential equalization.
Incorrectly connected potential equalization can generate potential differences that can
lead to explosions in an Ex-atmosphere.
▸
Connect potential equalization to all planned points.
▸
Ensure the potential equalization is connected during all work on the device
described in the Operating Instructions.
DANGER:
Risk of explosion when opening the MCUDH-Ex 3K control unit
The MCUDH-Ex 3K control unit must not be opened in Ex-atmosphere until 3 minutes
after switching off the power supply, so that the residual energy in the capacitors can
dissipate.
▸
Do not open the MCUDH-Ex 3K control unit in an Ex atmosphere until after the
waiting period.
▸
Take suitable precautions to prevent dust from entering the control unit enclosure
when the enclosure door is open.
