General Wiring Information
This section provides specifications and general information about wiring the MP501. The
controller requires wiring for:
•
Input/output terminal wiring
•
AC power wiring
•
Communication link wiring and addressing
Input/Output Terminal Wiring
All input/output terminal wiring for the MP501 must meet the following requirements:
•
All wiring must comply with the National Electrical Code™ (NEC) and local codes.
•
Use only 18 AWG, twisted-pair wire with stranded, tinned-copper conductors. (shielded wire
is recommended).
•
Binary input and output wiring must not exceed 1000 ft (300 m).
•
Analog input and output wiring must not exceed 300 ft (100 m).
•
Do not run input/output wires in the same wire bundle with any ac-power wires.
Note:
For application-specific wiring information and diagrams, refer to the sections,
“Applications for SCC Mode,” p. 13

AC Power Wiring
WARNING
Hazardous Voltage!
Before making line voltage electrical connections, lock open the supply-power disconnect
switch. Failure to do so may cause death or serious injury
CAUTION
Equipment Damage!
Make sure that the 24 Vac transformer is properly grounded. Failure to do so may result in
minor or moderate personal injury and/or damage to equipment.
CAUTION
Equipment Damage!
Complete input/output wiring before applying power to the MP501 controller. Failure to do so
may cause damage to the controller or power transformer due to inadvertent connections to
power circuits.
CAUTION
Equipment Damage!
To prevent controller damage, do not share 24 Vac between controllers.
