environmental conditions (temperature and natural conditions).
3. Each part of the system must maintain a connected earth ground.
ii. Before hardwiring the MBS unit outputs, ensure that there is no power
on the terminals.
iii. The protective cover on the terminal block should already be removed
from the last step.
iv. Feed the output cable(s) through provided cable gland(s) and
appropriate hole on terminal block housing.
Note:
Ensure that the cable
gland is separated on each side of the terminal block house to allow for
the cable to be secured to the housing.
v. Crimp a ring terminal onto each wire with a standard crimping tool for
the wire size.
vi. Connect each wire under the appropriate screw as indicated on the back
of the MBS (see the appropriate wire connection diagram in Figures 77
- 80 and bus jumpers in Figure 81).
Note:
Each part of the system must
maintain a connected earth ground.
vii. After completing the wiring, confirm again that all wiring is correct.
viii. Tighten the cable gland to the terminal block housing to secure the cable
to the UPS.
ix. Leave the terminal block cover off the housing for the next step of
connecting the UPS unit.
3. Connecting the UPS input to the MBS.
a.
Follow the steps as shown in the “Single Mode System Configuration with 3-
Phase or Single-Phase Output
” section (Step 1), except the UPS input cables
will be coming from the MBS instead of hardwires from a breaker panel.
4. Connecting the UPS output to the MBS.
a.
Follow the steps as shown in the “Single Mode System Configuration with 3-
Phase or Single-Phase Output
” section (Step 2), except the UPS output cables
will be going to the MBS instead of to the load(s).
5. Connecting the UPS system EBP to the UPS.
a.
Follow the steps as shown in the “Single Mode System Configuration with 3-
Phase or Single-Phase Output
