Warning:
To prevent electrical shock, do not apply electrical power to master, clock relays and clock wiring before
completing all wiring connections.
The AllSync Plus clock can run off either 24vac/60 Hz or 120vac/60 Hz. To change between the two different
supply voltages two jumpers must be set inside each clock. This setting is completed by American Time when
your clock(s) are built according to the part number ordered.
Caution:
Setting the AllSync Plus clock for 24vac and powering it with 120vac will damage the circuit board.
