CAUTION
In accordance with the safety standards of flameproof regulation, please comply with the
following instructions:
1. The voltage of general equipment such as the power supply and the receiver should not
exceed 250 V AC, 50/60 Hz, 250 V DC at any time at normal or abnormal operation.
2. 1) The ambient temperature around Magnetic Flowmeter is max.50°C (122°F).
2) The fluid temperature is 125°C (257°F) max. (The line size 10 mm (3/8 inch) or less
is 100°C (212°F).)
3) Please use specified flameproof cable gland adaptors.
4) Please do not open the case cover during operation.
5) Please wait for seven minutes after switching OFF the power supply, before opening
the front cover or side terminal cover.
