General Wiring Notes
The following important wiring guidelines should be followed:
1. Use a minimum of 18AWG wire for all connections.
2. Battery + and Battery - connections on the controller should be run directly to the positive and negative terminals on the
battery to prevent voltage drops from negatively impacting the controller.
3. Limit the wire length to 20ft (6.1m) to any I/O on the controller (e.g. Switched Input, Switched Outputs, AC Sensing, and
Analog Inputs).
The TOUGH Series contains a TVS to protect the I/O and internals from a transient on the main battery (the battery the
controller is powered from). If you have I/O connected to other batteries or power supplies those I/O must contain their own
voltage transient protection. Otherwise the I/O and/or controller can be damaged if the transient exceeds the maximum rated
voltage of the I/O. A device that provides this kind of protection is know as a TVS or a varistor.
4. The switched outputs already contain a kickback diode. Do not connect relays with an internal kickback diode to a
switched output as the output may be shorted. This included relays in the relaypak.
5. Fusing
a. A fuse should be placed inline with the battery + wire going to the controller power. A 10A fuse is suggested.
b. The AC Voltage A, B, and C lines should be fused near the source of AC voltage with a 1A fuse to protect personnel if
any of these lines become disconnected or damaged.
c. If using the RelayPak the power going to the relay commons should be fused.
6. For noisy environments some guidelines are:
a. Replace speed sensing wire with twisted pair from the sensor to the controller.
b. Consider using isolated sensors (i.e. two terminal) and use twisted pair wiring to connect from engine to controller.
The following enclosure guidelines should be followed:
1. It is recommended to use vibration mounts.
2. For outdoor applications, it is recommended to use a sealed enclosure.
