LIST OF
WARNINGS AND CAUTIONS
WARNING/CAUTION
When an external shut-down signal is sent to the unit, the shut-down con-
dition is latched and the red FAULT indicator on the front panel is ON. To
resume normal operation it is necessary to cycle power off, then on (pre-
ferred) or briefly press the RESET key on the front panel.
it is recommended that source power of external equipment connected to
the Analog Port be applied through an isolating transformer To avoid
ground loops or possible damage to the BOP due to incorrect equipment
a-c wiring (e.g., defeating of ground connection).
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).
When working with active loads, the voltage or current of the active load
must 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.
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.
Never connect the BOP OUTPUT terminal (or the load terminal tied to the
OUTPUT terminal) to earth-ground. Otherwise, if the controlling device is
grounded, the BOP can be damaged by the protection limit output current
flowing inside the BOP along the programming signal return path.
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 be
damaged by output current flowing inside the BOP along the program-
ming signal return path.
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 that
the 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 both
the BOP and the load in the event of input power loss.
For parallel configurations, Remove links between (COM S) and (COM
OUT) terminals of all slaves to prevent damage to the unit and maintain
system accuracy.
Connecting multiple units to different a-c input sources may damage the
BOP power supplies and/or the load.
Do not use the slave keypad, RS 232 port or GPIB port to try to control the
slave(s).
Pressing RESET will cause voltage transients to appear at the output
which may damage a connected load.
DO NOT repeatedly toggle the circuit breaker/switch as this may damage
the unit.
