Note
Except for the shorted copper bar 3, all the shorted copper bars mentioned in the installation procedures are the delivery
accessories.
1. Short the terminal bA, bB and bC of the single POD user terminal block using the shorted copper bar 7, short the
terminal oA, oB and oC using the shorted copper bar 5, and short mA and bA terminals using the shorted copper bar
6 and then short mN and bN terminals, two oN terminals respectively using two shorted copper bars 4, as shown in
Figure 2-9.

2. Connect the shorted copper bar 8 to one end of the shorted copper bar 7 (see Figure 2-9), and connect the live line
(input phase A) to the shorted copper bar 8.
3. Connect the live line (input phase B, phase C), N line and PE line respectively to mB and mC terminals of the
single POD user terminal block, shorted copper bars 4 of mN and bN terminals, and PE terminals.
4. Connect the live line (output phase A), N line and PE line respectively to the shorted copper bar 5 of the single
POD user terminal block, shorted copper bars 4 of the two oN terminals, and PE terminals.
5. Remove all the shorted copper bars 3 from the UPS I/O terminal block, and connect the UPS terminal block of the
single POD with the same silk screen terminal of the UPS I/O terminal block using the one-to-one correspondence
method.
6. As shown in Figure 2-10, you can paste the insulating film (accessory) to the shorted copper bar 10, and insert the
buckles into the corresponding holes on the shorted copper bar 10.
