5.1.2. Power Connection (Voltage Mode in Permissible Area)
Refer to Figure 4. To use the MC-4231-CO monitor in permissible areas, it is
necessary to make connections through a Class J barrier.
Please note the supply
voltage must be limited to 20 VDC.
Make connections from the
Blue Remote
to
the barrier and from the barrier to the MC-4231-CO monitor as shown in Figure 4.
Use the correct barrier classification types and use shielded cable between the remote
barrier and the MC-4231-CO monitor.
