2.2.2 Restrictions
1.
For the switch contacts, dimension and install a fuse with 0.6 times the nomi-
nal current.
2.
The maximum current load of the switch contacts must not exceed AC 1.4 A
and DC 0.4 A.
2.2.3 Comments
1.
Use as a limiter. Connect an external interlock downstream as a limiter,
which fulfils the requirements in accordance with VdTÜV code of practice
"Flow 100", edition 2017-03-15, sections 3.9, 5.4.1 and 5.6.
2.
Follow the manufacturer's commissioning instructions.
3.
IP ingress protection at supply line gland. Take care that the supply cable
used has a diameter that does not reduce the IP ingess protection of the
cable gland.
4.
Follow the manufacturer's installation instructions.
2.2.4 Special responsibilities for testing before commissioning
1.
The requirements of sections "2.2.2 Restrictions" to "2.2.4 Special responsibil-
ities for testing before commissioning" shall be reviewed.
2.
Carry out functional test of the installed instruments. For limiters carry out
additional control of the downstream interlock circuit.
3.
Follow the general technical regulations for pressure measuring instruments
(e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges").
