UL approvals
All standard (E)SNTL300P models:  BBGQ: UL1236, CSA22.2 no. 107.2; BBHH: UL1236 SE

Notes:
1) AC input fusing (F1): replaceable, circuit board mounted fuse, rating as shown on the product label.
2) DC output fusing: all models include a self-resetting electronic output fuse.
3) DC output is isolated from chassis.
4) connection shown for standard configurations with output RL4. (RL4 is not available on units configured for CAN communication)

Battery type is selected by circuit board DIP switches or SNTL-PCSUITE configuration software. Calibration figures at 20°C. If temperature compensation is enabled, and remote SNTL-RTC temperature sensor connected, output voltage automatically varies by 3mV per cell per 1°C deviation from 20°C, within the range –10° to +50°C. Increasing temperatures give decreasing outputs; decreasing temperatures give increasing outputs.
