5 Installation and Cable Connection
Acceptance Criteria
1. The cabinet is correctly connected to
the UPS.
2. Battery cabinets in parallel are
correctly connected.
NOTE
When ensuring that the SmartLi and UPS
are not powered on:
● If cabinets are installed close to each
other, use a multimeter to check
whether the copper bars of the
corresponding polarity in the adjacent
cabinets are conducted to verify the
wiring polarity.
● If cabinets are installed far away from
each other, short-circuit any wiring
copper bar and PE (enclosure) in one
cabinet, and use a multimeter to check
whether the copper bar of the
corresponding polarity in another
cabinet are conducted with PE
(enclosure) to verify the wiring
polarity. Before the copper bar in
cabinet 1 is short-circuited with PE, the
copper bar of the corresponding
polarity in cabinet 2 should not be
conducted with PE. After the copper
bar in cabinet 1 is short-circuited with
PE, the copper bar of the
corresponding polarity in cabinet 2
should be conducted with PE. After the
check is complete, remove the cable
between the copper bar and PE.
The pressure gauge pointer is in the
green zone and the pressure value is
greater than 1.6 MPa at 20°C.
The inside and outside of the cabinet,
and other operating components, are
free from conductive dust.
1. There is no foreign matter (such as
copper wires and screws) on the top
of the cabinet.
2. There is no foreign matter on the
copper bar terminals.
3. There is no foreign matter around
switch terminals.
4. There is no foreign matter on the
bottom plate of the cabinet.
5. There is no foreign matter on the rear
module subrack.
