NOTE
1. Control epuipment connected to the Model
SE14 magnetic flow converter must not use or
generate more than 250V rms or V dc.
2. Installation should be in accordance with the
National Electrical Code ANIS/NFPA 70.
3. The configuration of associated Apparatus
must be Factory Mutual Reseach Corporation
Approval under Nonincendive Field Wiring
Concept or be a simple apparatus (a device
which can neither generate nor store more
than 1.2V, 0.1A, 25mW, or 20 micro-J, ex.
Swithces, thermocouples, LED's and RTD's).
4. Associated Apparatus manufacture's
installation drawing must be followed when
installing this equipment.
5. Associated Apparatus connection is
representative of each input and output signal
connection. Each signal shall be wired in a
separate shielded cable.
6. No revision to drawing without prior Factory
Mutual Reseach Corporation Approval.
