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 other
connections. All input signals to, and output signals from, Moore Industries’ products should be
wired using a shielded, twisted pair wiring technique. Shields should be connected to an earth
or safety ground. For the best shielding, the shield should be run all the way from the signal
source to the receiving device (see Note below). The maximum length of unshielded input and
output signal wiring should be 2 inches.
NOTE:
Some of Moore Industries’ instruments can be classified as receivers (IPT2,
IPX2, etc.) and some can be classified as transmitters (TRX, TRY, etc.) while some are both a
receiver and a transmitter (SPA2, HIM, etc). Your shield ground connections should be
appropriate for the type of signal line being shielded. The shield should be grounded at the
receiver and not at the signal source.
CE Conformity
Installation of any Moore Industries’ products that carry the CE marking must adhere to the
guidelines in the Recommended Ground Wiring Practices section in order to meet the EN 61326
requirements set forth in the applicable EMC directive.
User Configurable Hardware
The HES has access to internal security jumpers with the ability to set them to read only (see
figures 3.6, 3.7.A, and 3.7.B). The jumpers are accessed by a sliding panel on the bottom of the
device (see figure 3.7).
Security jumpers are set by default to:
•
Network configuration = Read / Write
•
User configuration = Read / Write
CAUTION:
Please power down unit before accessing the jumpers.
