Installation

• Signal and communications cables shall run along grounded metal surfaces like metal
conduits, metal trunking or ducts, preferably away from power cables. They should
not run on open trays alongside power cables.

• The conduits shall be installed with insulated fixings as required to ensure grounding
only at one end. For conduit sizes follow the local electric codes.

• Shielded cables should have the shield grounded only at one end of cable segments
to avoid circulating currents through the shield.

5.2. Sensor Terminations Termination
SM sensors for a GuardII+ require a separate termination. Refer to the SM Sensor
Installation Guide for instructions to install the sensors and termination box.

5.3. Mounting Location

Excessive cable lengths distort SM signals. The standard GuardII+ SM installation kit
includes cables for connecting the monitor to the termination box; the distance from the
Terminal Box to the monitor should be less than 10 m (33’). If the cable lengths required
appear to be unavoidably long, please contact Iris Power LP for consultation or possible
alternatives.

Figure 5-1 GuardII+ SM Installation Location
Note:
Different GuardII+ monitoring technologies have different installation
location requirements. When deciding on the installation location for the
monitor, be sure to consider all the installed monitoring technologies.

5.4. Preparation

Once unpacked, the SM card should remain for at least two hours at the place of
installation to ensure ambient temperature equalization and to prevent moisture condensation
before energizing.
