Installation
Installation consists of physically mounting the unit
and completing the electrical connections.
Mounting
The SPA
2
is housed in a “universal” DIN case that
can be mounted on both 35mm G-type (EN50035) and
35mm Top-Hat (EN50022) DIN-rail.
To mount the SPA
2
on a Top-Hat DIN-rail, seat the
upper extrusion on the unit back panel over the top
lip of the rail and pivot downward until the housing
locks into place.
To mount the unit on a G-type rail, seat the
extrusion under the top lip of the rail and again,
pivot downward.
When mounting multiple units, like a rack or
cabinet, make sure to allow adequate vertical
spacing for pivoting the units.
Making the Electrical Connections
Refer to Figure 3 (SPA
2
Front Panel Configuration) or
Figure 19 (SPA

PC Configuration) for electrical con-
nections.
Recommended Ground Wiring
Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case or
housing should be grounded.
• The protective earth conductor must be
connected to a system safety earth ground
before making any other connections.
• All input signals to, and output signals from,
Moore Industries’ products should be wired
using a shielded, twisted pair technique.
Shields are to be connected to an earth or
safety ground at the unit itself.
• The maximum length of unshielded input
and/or output signal wiring should be
two inches.
