The 230 V supply must include a dedicated 5 A fuse complying
with IEC60269 (BS1362) and a suitably rated switch in close
proximity and be clearly marked as the disconnecting device
for the unit. A 5 A circuit breaker with high breaking capacity
may be used as an alternative.
/24VAC 24 Vac ±10% 50/60 Hz at up to 28 VA
The 24 V supply must include a suitably rated switch in close
proximity and be clearly marked as the disconnecting device
for the unit. If one side of the supply transformer’s secondary is
earthed (grounded), it MUST be connected to the controller’s
0V terminal (terminal 2).
