Acroprint ESP180 Time Stamp - Manual (Page 9)

9 Setup
The power cable is then inserted into
the recessed area on the bottom of
the clock. Push the cable into the
opening, being careful to hold the
cable straight until the connector is
snug.
As a precaution against the power cord
accidentally being pulled out, you may
loop the power cord back around the tab
and then through the notch.
When the bracket is reinstalled, be careful
not to pinch the power cord between it
and the unit.
If you want to mount the unit on a wall (see Section 2.5), be sure
to install the ribbon first (see Section 2.4). You can fasten the
mounting bracket to the wall and attach the clock before you
begin programming.
