Safety
Always disconnect the mains supply before you remove the cover
from the power supply unit. Never operate the power supply with the
cover removed.
Siting
The PSU should be sited indoors on a vertical wall in a secure area as
close as possible to the Controller(s) it is powering, out of direct
sunlight. If you are using the auxiliary power output from one or
more Controllers to drive high current consuming equipment such as
lock strikes then remember that the total cable run from PSU to
Controller and Controller to lock strike should be as short as
possible. If long cable runs are required then the conductors have to
be of a heavy gauge to prevent too much voltage drop.
