Caution.
• Refer to SPECIFICATION SHEET for Input/Output ratings.
• Inductive loads must be suppressed or clamped to limit voltage swings
• Capacitive loads must be inrush current limited.
• Hazardous area requirements are not considered in the following pages.
Note. The connection terminal markings in the metal housed transmitter are identical to those in
the standard transmitter as shown in this section. However, the supply connection in the former
is made using a non-reversible plug (provided).
