Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).
Run the ground connection from the E arth GN D screw to the grounding surface prior to
connecting devices.

Power Inputs
The iES28TG supports dual redundant, hot swappable power supplies, Power Supply 1 (PWR1) and
Power Supply 2 (PWR2). The connections for PWR1 and PWR2 are located on the terminal block. To
connect power, follow the steps below:
1.
Remove the cover designed for protection from the terminal block.
2.
Connect the ground from the first power source to GND1 terminal screw.
3.
Connect the Positive or Live from the first power source to the POWER 1 V+/L
terminal screw.
4.
Connect the Negative or Neutral from the first power source to the POWER 1 V-/N
terminal screw.
5.
If a redundant power supply is required repeat steps 2 to 4 connecting the wires from
the second power source to the POWER 2 terminal screws.
6.
To keep the wires from pulling loose, use a small flat-blade screwdriver to tighten the
wire-clamp screws on the front of the terminal block connector.
7.
After wiring is completed, put the transparent cover back onto the terminal block
