This equipment is suitable for connection to 90-264 Vac or 24 Vac/dc,
50/60 Hz, power supply mains. It is the user's responsibility to provide a
switch and non-time delay (North America), quick-acting, high breaking
capacity, Type F, (Europe) 1/2 A, 250 V fuse(s) or circuit-breaker for 90-
264 V; or 1 A, 125 V fuse or circuit breaker for 24 Vac/dc operation, as
part of the installation. The switch or circuit-breaker should be located
close to the controller, within easy reach of the operator. The switch or
circuit-breaker should be marked as the disconnecting device for the
2
controller (4 mm ).
CAUTION
Applying 90-264 Vac to a controller rated for 24 Vac/dc
will severely damage the controller and is a fire and smoke hazard.
When applying power to multiple instruments, make sure that sufficient
current is supplied. Otherwise, the instruments may not start up normally
due to the voltage drop caused by the in-rush current.
