(1) DC Good signal is a 1mA conductance signal which indicates that DC output voltage is greater than 90% of nominal voltage.
AC good signal is a 1mA conductance signal which indicates adequate input capacitor energy storage to provide 10msec holdup.
DC output voltage will remain within regulation limits for a minimum of 10msec after AC Good signal ceases to conduct.
AC Good signal is initiated approximately 2 seconds after input power is applied.
(2) Overload of power supply does not cause fuse failure. Replace only with same type and rating.

(3) The total output power for V2,V3,V4 outputs should not exceed 110w for Fan Cooled and 100w for Non-Fan Cooled Units at 50°C.
(4) Remote sensing on the main output is accomplished by removing JP1 and JP2 from the printed circuit board and connecting
the load to the +S1 and -S1 terminals found on J3. The maximum cable drop is 0.5 volts.
(5) Minimum load on V2 and no load on auxiliaries.
(6) Peak output current lasting less than 30 seconds with a duty cycle of < 5%. During peak current transients the outputs may

Notes:
- Short circuit protection on auxiliaries is limited to 30 seconds or damage/failure to unit may occur.
- Operation of the unit between the line voltages of 132 and 180Vac for greater than 30 seconds will cause
catastrophic failure to the unit.
- All outputs are derated with the Z option (cover) chosen. See derating table.
- Proper air circulation is required when the unit is mounted in confined areas.
- Remote on/off - J8 is a primary referenced connector located in the center of the unit.
Short J8 terminals = unit off, open J8 terminals = unit on
Note: This is a primary referenced circuit and requires proper agency clearances.
The use of an opto isolator is recommended.

* For positive ground, move the -V to gnd jumper to +V to gnd, as shown with dashed line.
** JP1 and JP2 must be removed for unit to operate in remote sense mode.
Remote sense minimizes the effects of distribution losses by regulating
the voltage at the remote sense connections. Good layout techniques,
such as close proximity and directness, should be observed for noise immunity.
*** Suitable decoupling capacitor (0.1uF, or higher) may be required at load.
