SUMMARY OF INDICATORS AND CONTROLS
SYSTEM POWER SWITCH - The main control switch that engages utility power to the entire unit.
By activating this switch it initializes normal operation.
DC INPUT - A two pole, 20A (25A for SP1250PD (PLUS) & SP2000PD) circuit breaker used to
connect the battery to the internal UPS electronics. It also protects against over-current situations
in the battery circuit.
INPUT AC LINE BREAKER - The input line protection device to limit excessive current draw to
the system on over-loads. Rated 15A/250V (20A for SP1250PD (Plus) & SP2000PD).
COLD START - A momentary push-button switch to activate the system in the event no utility
power is available. The system will be allowed to start up by using power from the battery.
Depress this switch, the indicator above it will light, and hold it in until the audible alarm beeps
once. The system will maintain a load for a period of time depending upon the condition of the
battery. DC INPUT breaker must be ON.
ALARM - This is a fault indicator that will light in the event that the inverter generator is non-
operable. This could be due to an over-temperature situation or an inverter malfunction.
NOTE - Cold Start and Alarm Silent switches must be held in for at least two
seconds to engage their function. This is to prevent any inadvertent switch
operation.
RS232 - A DB-9 subminiature, female connector that outputs true RS232 communications
signals.
UPS OUTPUT - A NEMA type duplex, 5-15R output connector that provides continuous power.
This receptacle is connected to the bypass line when the inverter is not running.
UPS OUTPUT CIRCUIT BREAKER - A 15A protective circuit breaker. Protects the UPS
OUTPUT 5-15R connector noted above.
SIGNAL - A DB-9 subminiature, female connector that outputs the open-collector signal contacts
that generate a low state during utility interrupt, low battery and inverter off conditions.
AC INPUT - A six-position plug in connector provided for AC power to and from the UPS to the
Bypass Box.
DC INPUT - A two-position connector provided for battery power to the UPS.
RELAYS – Six or Eight sets of normally open (NO) and normally closed (NC) contacts. These
contacts are programmable thru the LCD display. See section 4.10 for instructions.
LCD DISPLAY & PUSH BUTTONS – An LCD Display showing UPS system data, status and
settings. See section 4.
