Installation
Power supply
The variants of the module GPS164xHS are designed for following power supply
options:
GPS164DHS
and
GPS164/AQ/DHS:
19...72 VDC (DC-insulation 1.5 kVDC)
GPS164AHS
and
GPS164/AQ/AHS:
100...240 VAC, 47...63 Hz
GPS164DAHS
and
GPS164/AQ/DAHS :
100...240 VDC
100...240 VAC, 47...63 Hz
The voltage feed of the DC variants is done via terminal blocks in the frontpanel of
the clock and should have low resistance to minimize spurious emission (EMI). The
AC models include a fuse which is available at the front panel.
To avoid potential differences between the signal ground of GPS164xHS and a
post-connected unit installed on different DIN rails, the signal ground of the clock is
insulated from the case.
The case must be grounded by using the rear contact.
