4.3 Installing UPS external battery cabinet and battery
power wiring
For the 93PM product line, there are two different battery cabinets: EBC-S and EBC-L. The 93PM
30-50 kW UPS uses 36 battery blocks per string, and the 80-200 kW UPS uses 36 or 40 battery blocks
per string.
NOTE
Battery strings with different battery quantity and voltage may not be connected in parallel.
Power and control wiring for integral line-up and match battery cabinets are supplied with the
cabinets. The battery cabinet must be located to the right of the 93PM 30-150 kW UPS cabinet if
wiring through cabinet inside panels. The 93PM 160-200 kW UPS does not enable wiring though its
side panel.
There are several cable entries in the battery cabinets. They can be wired in the following ways:
• through the left side panel
• through the right side panel
• through the back wall
• through the roof
• through the bottom (only EBC-L)
Cable entry to the UPS is always on the back wall or the bottom of the cabinet, and to 30-150 kW
UPS also on the lower right.
NOTE
If batteries are wired outside the cabinets, follow the installation instructions given in Chapter
3.2.2 UPS system power wiring preparation on page 30.
