Additional battery strings can be daisy-chained to the UPS internal battery system via a unique connector inside the UPS battery
compartment (Figure 3.10a).
A 15-ft. BP240EXTNDR15DL cable is required to connect the rst battery cabinet to the UPS system (Figure 3.10b). Cabling for all
additional built-to-order cabinet installations is the sole responsibility of the electrician performing the installation.
To connect the cable to the UPS, remove the cover plate (Figure 3.10c) and insert the Delta connector into the slot until it is seated
rmly. After removing the cover plate, run the ring terminal ends through the opening and connect to the breaker (see section 6.2).
Make sure to use the correct electrician-provided strain relief at the cover plate.
Warning: When connecting to the breaker, make sure that you maintain proper polarity (positive to positive, etc.). Failure to do so
may result in damage to your UPS and will void your warranty claim.
