2.1

Ammeter

The front panel ammeter displays output current flowing from the power module into the load.

It is extremely useful in determining the status of the plant during maintenance and trouble-

shooting. When there is no load at the output, the ammeter reads zero. When the meter

reads above the rated output of the APP60S, such as 18 or 20 Amps, an overload or short

circuit condition may exist in the load.

2.2

The 15 Amp AC output fuse protects the load from excessive durations of short circuit current.

If the front panel ammeter reads zero, indicating no output to the load, this fuse should be

checked and replaced if necessary.

2.3

The 12 Amp AC input fuse protects the APP60S from short circuit conditions, especially when

it is used in conjunction with a generator during outage conditions. If the unit does not come

ON when power is applied, first verify that the unit is plugged into the convenience outlet and

that the main AC circuit breaker is in the ON position. Then check the input fuse and replace

it if necessary.

2.4

AC LINE Indicator (Green)

The AC LINE indicator displays the presence of utility AC at the input. If the indicator does

not light when the unit is switched ON, first verify that the unit is plugged into the convenience

outlet and the main AC circuit breaker is in the ON position. If necessary, check the AC input

fuse and replace it if necessary.

2.5

The 30 / 60 VAC switch is used to select the desired output voltage. For 50 Hz applications,

the switch is configured for 48 / 60 VAC.

2.6

The ON / OFF switch is used to apply or remove power from the APP60S.

2.7

The APP60S "Jones" connector plugs directly into the Service Power Inserter's mating

connector to provide output power to the load. Note: The SPI's "ALT/ON" switch must be in

the "ALT" position to accept power from the APP60S.

2.8

The APP60S AC line cord plugs directly into the enclosure's convenience outlet.
