Warning!
Use caution when handling live electrical connections. Do not install
electrical equipment in wet or damp conditions. Do not allow anything to
rest on the power cable, and do not place the cable where people can
stand or walk on it. Verify that the IES is bonded before connecting
power.
The unit is required to be bonded to a safety earth (ground) using a suitably rated cable:
Cable gauge: 18 AWG minimum required (4 sq mm minimum suggested)
Cable length: depends on the field environment. Use the shortest path to the ground.
Type of cable terminal: gauge 4~4.5 mm recommended
Type of cable: sleeved
Cable color: green and yellow required by safety
The cable must be attached to the IES using an M4 machine screw with a suitable lock washer. The
other end must be securely fastened to the chassis ground with a lug and screw arrangement of
M3.5 or greater. An example is shown in Figure 5 on page 18.
The frame ground is on the upper left of the chassis front panel.
Connect the frame grounds to a building’s protective earthing terminals using a green-and-yellow
frame ground wire.
Warning! Bond the frame ground before you connect any other cables or
wiring.
