6. Hold-up Time
AC 100V AC 120V AC 230V
Hold-up Time typ. 36ms 54ms 218ms at 24V, 1.25A, see Fig. 6-1
typ. 15ms 24ms 107ms at 24V, 2.5A, see Fig. 6-1
Note: At no load, the hold-up time can be up to several seconds. The green DC-ok lamp is also on at this time.

7. DC Input
The power supply can also be supplied from a DC source. Use a battery or similar DC source. For other sources, contact
RA. Connect the + pole to L and the – pole to N. Connect the PE terminal to an earth wire or to the machine ground.
