The System 10K uses only three-wire grounded power plugs. The third wire

ground can cause a ground loop with your facility ground. If you are sure your

facility ground will provide adequate protection to personnel in case of an AC line

short to chassis, a 3-to-2 AC adaptor can be used to isolate the power line

ground. We recommend that the adaptor be removed and the power line ground

reconnected prior to any service work requiring removal of the facility ground

from the chassis.

To allow maximum flexibility in grounding in high RF environments, the circuit

grounds are isolated from case ground. An individual circuit ground is available

next to the HI input terminal of each module. These grounds are already

interconnected through the common DC power supplies. It is not recommended

that the individual circuit grounds be tied together since a ground loop would

result. A common DC ground is available on the ALARM terminal block pin 3.

This ground may be interconnected, tied to chassis or connected to a studio

ground system.

ALARMS

Alarm lines from the two power supplies are paralleled and brought to a barrier

block mounted on the left hand rear sidewall. The power alarm is connected to

pins 1 and 2. The power alarm outputs are reed relay contacts which close if

either or both DC output voltages drop below 11 volts due to excessive loading,

blown fuses or loss of AC power. The reed relay contacts should not be used to

switch high current lamp loads or AC line voltages. Several racks of distribution

amplifiers may be paralleled into a single alarm interface.

The PS100 Power Supply incorporates dual

transformer primaries that can be strapped for 115 or

230 VAC operations. To use on 230 VAC power,

remove jumpers J1 and J3 from the solder side of the

PSI00 PC Board and insert a jumper in the J2

position.

Each PS100 of a redundant powered system may be

operated from a separately fused AC system for even

greater reliability. An additional AC line cord is

required and replaces the AC jumpers between the

power blocks of the two PS100 modules.
