If the tolerance of the supplied supply voltage is not observed, or if another type of voltage is used, the correct operation of Master clock cannot be guaranteed.

[2] (1,2)

The total power supplied to the connected equipment consists of consumption of the secondary line, consumption at the ACCU and VDC terminals; the maximum values of the specified currents cannot be supplied to the load at the same time.

If the Master clock is powered though +ACCU– connector from a permanent 12–14 VDC power supply, the “Accu connect” jumper needs to be installed.

Do not install the jumper if the Master clock is powered by mains 230 VAC (115 VAC) and equipped with an active battery back-up (12 V accumulator connected to +ACCU–).
