Connecting earth cable
Note
1. The grounding bar of each cabinet is located on the bottom of the cabinet or on the equipment rack, which should be
respectively connected to the earth metal base reliably.
2. The grounding bar in the equipment cabinet has two M8 screws and ten M6 screws, and that of the battery cabinet has two M8
screws and one M6 screw.
The connecting procedures of earth cable are as follows:
1. Led the earth cable through the cable entry holes and route the cable along the cable holder.
2. Connect one end of the earth cable to the grounding bar (see Figure 2-20) in the cabinet, and solder the other end
to the earth metal base reliably.
3. Use nylon cable ties to tie the earth cable to the cable holders.

Connecting AC input cable
Note
1. Reverse connection of the AC input live line (L) and neutral line (N) is strictly prohibited. Or else, an equipment fault will be
caused.
2. Use sheathed cable. Ensure that the protective earth (PE) cable must be longer than the live line and neutral line. This can
avoid hazards as the PE cable is disconnected before the live line and neutral line when you pull cables.
3. For the thermal control system configured with an air conditioner, the AC input range: 220Vac to 230Vac/50Hz must be
ensured.
The routing of the AC input cables is the same as that of the earth cable.
