F BOP 1KW OPR 3/19/12LIST OFWARNINGS AND CAUTIONSPAGE WARNING/CAUTION2-6 CAUTION: it is recommended that source power of external equipment connected tothe Analog Port be applied through an isolating transformer To avoidground loops or possible damage to the BOP due to incorrect equipmenta-c wiring (e.g., defeating of ground connection).2-8 CAUTION: The rack must provide support at the rear (within 6 inches of the rear pan-el). Optional slides can also be used (see PAR. 2.4.2).2-8 CAUTION: When working with active loads, the voltage or current of the active loadmust not exceed the maximum voltage or current rating of the BOP. Oth-erwise the overvoltage or overcurrent protection will shut down the pow-er supply.2-10 CAUTION: Never connect the load to the sense terminals. Monitoring instruments(e.g., DVM, etc.) are the only external equipment that may be safely con-nected to the sense terminals.2-10 CAUTION: Never connect the BOP OUTPUT terminal (or the load terminal tied to theOUTPUT terminal) to earth-ground. Otherwise, if the controlling device isgrounded, the BOP can be damaged by the protection limit output currentflowing inside the BOP along the programming signal return path.2-10 CAUTION: Do not connect both the load and the programming device return (com-mon) to earth-ground potential. Otherwise, If the COMMON power con-nection between the BOP and the load is lost, then the BOP can bedamaged by output current flowing inside the BOP along the program-ming signal return path.2-10 CAUTION: The safety features incorporated into the BOP to handle energy from Ac-tive loads are unable to protect the power supply or the load if input pow-er to the BOP is lost or if the BOP Malfunctions. It is recommended thatthe user monitor “Power OK” flag pins 3 and 4 of the external Protect Port(see Table 2-4) and implement a fast-acting means of disconnecting ca-pacitive loads or crowbarring inductive loads to prevent damage to boththe BOP and the load in the event of input power loss.2-14 CAUTION: For parallel configurations, Remove links between (COM S) and (COMOUT) terminals of all slaves to prevent damage to the unit and maintainsystem accuracy.2-14 CAUTION: Connecting multiple units to different a-c input sources may damage theBOP power supplies and/or the load.2-20 CAUTION: The units are now configured as slave(s) to be controlled only by the master.Do not use the slave keypad, RS 232 port or GPIB port to try to control theslave(s).3-3 CAUTION: Pressing RESET will cause voltage transients to appear at the outputwhich may damage a connected load.3-5 CAUTION: DO NOT repeatedly toggle the circuit breaker/switch as this may damagethe unit.3-12 CAUTION: When the ADJUST control is rotated, the active parameter is immediatelyeffective if the output is enabled (on = STANDBY indicator not lit). Thevoltage/current applied to the load changes as the ADJUST control is ro-tated.
