WARNING
This panel system is
wired for AC voltages
that can injure or kill.
Wiring should be performed by
quali¿ ed personnel only.
Disconnect AC power before opening wiring enclosure.
Follow all local and government recommendations and
methods for installation of electrical connections to and
between the system and other devices.
Wiring Label Legend
Ground
Earth Ground. Attach 4 to 20 mA loop cable
shield wire here to help eliminate possible noise.
Loop 1 4 to 20 mA Loop #1
Loop 2 4 to 20 mA Loop #2
Relay 1 Relay Output #1
NC
Relay Normally Closed (contact) when
de-energized
C Common
NO
Relay Normally Open (no contact) when
de-energized
Relay 2 Relay Output #2 (terminals same as Relay #1)
Output Connections
• Use the wiring enclosure terminal block for output wire
connections. Do not wire directly to the transmitter.
• Recommended torque for the terminals is 7 lb-in
• Do not run 4 to 20 mA loop cables in the same conduit as
the power or other high voltage wiring.
• Remove one installed jumper wire (from both of its terminals)
on the terminal block in the enclosure for each loop device
connected. Replace the jumper if you later remove your
loop device. If only one loop device is connected, remove
just one jumper wire from its two terminals.
• The panel system uses an active loop output wired to the
enclosure terminal block.
• If connecting to a PLC, use the PLC's passive input.
• The transmitter must have a jumper wire or loop
device always connected to Loop 1.
