WARNING
!
Do not disassemble the EA_Gatekeeper enclosure, service the gatekeeper unit, or service the components inside the unit
with power present. Use authorized utility procedures to install and service equipment. Dangerous voltages are present.
Equipment damage, personal injury, and death can result if safety precautions are not followed.
The instructions for removing the electronic assembly are the same for all communication options. See Figure 1 for an
illustration of the Ethernet and telephone (POTS/PSTN) communication options; see Figure 2 for the cellular modem
communication option; see Figure 3 for the RS-232 communication option. The numbered items in all figures refer to the
following removal instructions:
How to remove the existing module
1.
Switch the AC circuit breakers to the “off” position.
2.
Remove the fuse from the fuse holder.
3.
Disconnect the communications or crossover (for cellular modem styles) cable from the surge suppressor.
4.
If present, remove the Kapton tape securing the electronic assembly to the meter base (approximately a 2-inch
strip located at the 12 o’clock position).
5.
Disconnect the red DC power cable by loosening the terminal block that holds the cable.
6.
Rotate the electronic assembly counterclockwise and gently lift it from the meter base.
