How close can I install the pump start relay to the controller?

I'm going to install a pump start relay, I was wondering if it is right to have it next to the timer, or it can have a negative effect on the controller.

Thanks

From Hunter's website http://www.hunterindustries.com/support/there-minimum-distance-pump-start-relay-must-be-irrigation-controller

"While most of the time the distance between the controller and pump
start relay doesn't create any problems, every once in a while the wires
on the 24V coil can allow electromagnetic noise to travel back to the
controller. This noise is made when the contacts on the pump start relay
make and break the connection.
It's recommended to use a minimum
distance of 15ft (4.5m) separation between the controller and the relay,
to help dampen any electromagnetic noise.
In addition to this
recommendation, Hunter also recommends all controllers be mounted 15ft
(4.5m) away from pumps and high voltage devices."
