Installation and User Manual
3.2.2 Post Start Up Safety Check List
After initial start up of the system, normal operation of the STS should be verified. At the minimum, the following should
be checked as applicable to your installation:
◗ Remote emergency power off (REPO) operation (all switches in the STS should trip off). After this test, reset
all switches in the OFF position and repeat the start up procedure.
◗ Maintenance bypass procedure.
◗ Proper readings on the LCD display for Voltages, Current, Frequency and Power.
◗
Operation of the Manual Control pushbuttons (“hard keys”) on the front panel.
CAUTION
EXPOSURE TO HAZARDOUS VOLTAGES.
Dangerous voltage levels are still present inside the
STS cabinet. When bypassed/isolated, control power
supply circuits are still live and power is
provided for indicator lights and emergency power off
circuits. Disconnect all sources of power before
servicing. Refer servicing to qualified service
personnel.
3.2.3 Shutdown Procedure
To isolate and shutdown the static switch section of the STS:
1. Check that the desired bypass source is available and that the LCD and mimic diagram display indicate that the
static switch is on the desired bypass source.
2. Follow the Bypass Procedure to bypass the static switch and connect the load through the bypass switch to the
desired bypass source. Isolation switches CB1, CB2, CB3A and CB3B (if installed) will be in the OFF (or
Tripped) position.
