Sensor AC mains supply connections
Connections for AC mains supply to the sensor are to the dry sensor board (see
Figure 3-12). They are labeled as follows:
L - Line Connection
N - Neutral (USA)
Chassis Stud -Equipment Ground (Protective conductor)
AC (L) and (N) markings are provided by the terminal block for con-
nection of AC power.
These markings are for reference purposes only such as for use on
system wiring diagrams etc. The system/product has or needs no
specific LINE or NEUTRAL connection for any function, safety or
otherwise. The (N) terminal is not internally grounded, nor needs to
be. The system will operate normally regardless of what AC input
terminal (L or N) that AC Line or Neutral is connected to, or, if there
is a Neutral used at all (i.e. 208 VAC US power connection).
There is no power switch on the sensor, and it must be protected by installing it on
a circuit protected line, maximum 15 amperes, with a switch or circuit breaker in
close proximity to the sensor and within easy reach of an operator. Mark the switch
or circuit breaker as the sensor disconnecting device.
