10 CopperLink 1101E/IP67 Quick Start Guide
6.0 Connecting to the grounding screw on the Remote unit
As a standard safety practice, the chassis of the CL1101E/IP67 must be properly
grounded to protect against any contact with an electrical fault condition.
Do the following to connect to the CL1101E/IP67 to ground:
1. Run an un-terminated ground cable through the gland labeled with a ground sym-
bol (see figure 3 on page 5).
2. Terminate the cable with the spade lug provided with the unit or your own terminal.
3. Remove the grounding screw (see figure 6 on page 7).
4. Attach the ground cable to the steel plate using the grounding screw.
5. Connect the other end of the ground wire to an electrical ground nearest the
CL1101E/IP67. Often this will be on an electrical panel or sub panel. If you cannot
locate a nearby electrical ground, contact Patton Technical Support at (301) 975-
1000 to discuss an alternative grounding solution.
Note Keep the length of the ground wire as short as possible.
6. Verify that the resistance of the ground path is less than 0.5 ohms.
7.0 Connecting power to the Local unit
Note The Local CL1101E/IP67 does not have a power switch, so it powers up
as soon as it is connected to a power source.
An external AC to DC adapter is supplied with the units. No configuration is necessary
for the power supply.
Note DC power must meet the following requirements; DC power supplied
must be regulated 12 VDC ±5% to 54 VDC ±5%.
Do the following to connect the power cable to the Local unit:
1. Run an un-terminated power cable through the gland labeled Power (see figure 5
on page 7).
2. Connect the cable wires to the terminal block shown in figure 5. Be sure to match
the cable wires polarity with that of the terminal block.
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
