2.0 Installation
This section provides an overview of LaserLT-60 and LaserLT-100 installation.
Install the instrument on a stable, vibration free, flat surface. Disconnect from power source to completely power off the
instrument. The back mounting bracket is for vertical mounting. An optional side mount for horizontal surfaces is available for
the LaserLT-100.
Remove protective film from the overlay as it may become difficult to remove if exposed to heat or sunlight.
2.1 Grounding the System
For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in proximity of the
instrument on which to connect the ground of the instrument, an interface cable and shields. Connect the ground point of the
remote display directly to the ground bar of the electric panel or to a grounding rod.
2.2 Wiring Schematic
For proper device wiring, refer to the schematic below:
Figure 2-1. Wiring Schematic
Pins 3 – 12 and 18 – 35 are not used for remote display models.
2.3 Power Supply
The instrument is supplied with an AC power cord, connected to an internal AC/DC power adapter. To power the instrument
with 12 VDC or 24 VDC, connect the power supply cable directly to the terminal strip on the CPU board, see J1 in Figure 2-1.
This input is for static DC, not for an automotive source.
The maximum power of the outputs 48 VAC 0.15A max (or 60 VDC 0.15 A max), the maximum voltage applicable to the inputs
is between 12 VDC and 24 VDC with current from minimum 5 mA to maximum 20 mA.
