AC-power wiring
WARNING
HAZARDOUS VOLTAGE!
Disconnect all electric power including remote disconnects before ser-
vicing. Follow proper lockout/tagout procedures to insure the power
can not be inadvertently energized during installation or servicing. Fail-
ure to disconnect power could result in death or serious injury.
WARNING
Hazardous voltage!
Make sure that the 24 Vac transformer is properly grounded. Failure to
do so could result in death or serious injury and/or damage to equip-
ment.
CAUTION
Complete input/output wiring before applying power to the Tracer
MP503 I/O module. Failure to do so may cause damage to the device or
power transformer due to inadvertent connections to power circuits.
CAUTION
To prevent device damage, do not share 24 Vac between devices.
The recommended wire for ac power is 16 AWG (1.3 mm
2
)copper wire. All
wiring must comply with National Electrical Code and local codes.
The ac-power connections are in the top left corner of the Tracer MP503 I/
O module (see Figure 3 on page 7).
