UA 300 D xS control panel mounting
The UA 300 D xS is housed in a plastic casing designed for panel mounting. Power loss is approx. 10 VA. When
installing, make sure to provide sufficient clearance between devices or cable ducts above and below the con-
troller for proper removal of heat. The controller can be started on completing mechanical and electrical installa-
tion.
All leads running to and from the UA 300 D − especially those of the CAN bus − must be shielded! No
shielding is required on sensor leads when installed exclusively inside the refrigerated display case
and when external interference (for example from parallel power wires) is not to be expected.
Electrical enclosure, measurements and panel cutout are described in Section Specifications. Pin
and terminal assignments are listed in Section 5.
Attaching mounting braces and installation
The two mounting braces enclosed with the UA 300 D xS must be attached on the left and right sides of the ca-
sing for installation:
1. Push front of UA 300 D xS (2) through cutout in control panel (1).
Press fastening brace (5) on front support pin (3).
