Mounting the Master Clock

The master clock is shipped ready to surface mount on a wall. It can also be semi-flush mounted with the power supply recessed into the wall, or installed in a standard 19-inch (48.3 cm) rack. See Figure 1-1for wall mount assembly parts. The display unit can also be hung on the wall with the power supply hidden in the floor or ceiling; contact Lathem for details.

A qualified technician should install the master clock. The installation does not require any special tools, but may require extra hardware, wire, or other materials as required by local electrical codes.
