Connect the DC+ and DC- cables to the DC+ and DC- terminals. Connect the power cables in the UPS. If more battery cabinets are part of the solution, connect all battery cabinets to the UPS according to the diagram below.
Connect and route cables from positive (+) and negative (–) terminals in the bottom of the first battery cabinet into the UPS cabinet. Connect the (+) lead to terminal E4 (+) and the (–) to terminal E5 (–) in the UPS cabinet.
Refer to the appropriate Powerware 9390 UPS Installation and Operation Manual, as referenced in paragraph 1.6, for UPS cabinet terminal locations. A UPS‐to‐battery wiring harness is supplied inside the first battery cabinet. Use pressure and bus bar terminations, as necessary, for connecting cables between the UPS and battery cabinet.
Secure the battery cabinet position by lowering the leveling feet until cabinet is not resting on the casters. Ensure the cabinet is level and matches the height of the installed UPS cabinet. NOTE Two cabinet joining brackets are provided in the field kit for securing each cabinet at the top and bottom.
The battery cabinet may be located to either the left or right of the UPS cabinet. The recommended location is to the left of the UPS cabinet. This procedure assumes the battery cabinet is located to the left of the UPS cabinet. Figure 3‐2. UPS with Line-up-and-Match IBC-S
Create an installation plan for the battery cabinet (Chapter 2). Prepare your site for the battery cabinet (Chapter 2). Inspect and unpack the battery cabinet (Chapter 2). Unload and install the battery cabinet, and wire the system (Chapter 3). Complete the Installation Checklist (Chapter 3).

The connection of the neutral line of the power transformer is a technical problem, which plays an important role in the power transformer and stability. There is a way to connect
Route the ground wire (from the field kit) from the ground stud in one battery cabinet, under the lower battery tray and through the cabinet-to-cabinet cable access area in
In connecting external batteries to the UPS, 4 terminals are given +,N,- and PE. I understand +,- and PE, but for what "N" stands for? is it
The term line-up-and-match refers to battery cabinets that are physically attached to the UPS, share internal wiring, and use the battery cabinet breaker as the battery isolation
By grounding the neutral at the main panel, it stabilizes the voltage and prevents fluctuations. This is why the neutral and ground must be bonded
Route the power cables through the gland plate and connect to the terminals: Connect the PE cable to the PE terminal/Connect the EGC cable to the grounding terminal. For installations
As the interlocking arrangement involves the mandatory avoidance of mixing of phase as well as neutral between the different raw power supply sources, there is a likely
e wires on your e-bike that connect to the battery. Typically, these wires will be color-coded, with re indicating positive and black indicating negative. Connect the positive terminal of the battery
It is probably done to avoid high output voltages out of the ups. The UPS takes the neutral as the reference point and works out the voltage on the output. The trouble is the
For battery cabinets that are connecting to a VertivTM Liebert® EXS UPS, see Figure 2.1 on page 8, cables will run from the positive, negative and neutral busbars of the
