Electrical Connections and Descriptions
All electrical connections to the STM-100 / MF are made at the rear panel of the
instrument. Care should be exercised in routing all cables as far as practically
possible from any other cables or wires that may be generating noise. These may
include other line voltage cables, wires to heaters that are SCR-controlled, and
wires or cables that may conduct high transient currents during arc over of an E-
beam type supply.
Figure 3.1: Rear Panel.
WARNING OPERATING THE STM-100 / MF AT 220V WHEN THE
UNIT IS CONFIGURED FOR 110V MAY CAUSE
DAMAGE TO THE UNIT.
REPLACE BROKEN OR BLOWN FUSES ONLY WITH
TYPE 3AG SLOW BLOW OR EQUIVALENT WITH THE
RATINGS SPECIFIED. FAILURE TO DO SO MAY
RESULT IN UNSAFE OPERATION AND MAY CAUSE
DAMAGE TO THE UNIT.
The STM-100 / MF may be configured to operate on either 110V or 220V
nominal line voltage. Units are factory-shipped configured for 110V operation
unless otherwise ordered. The setting may be verified by noting the line voltage
value visible in the small window of the power and fuse module. To change the
configuration first remove the power cord, then release the latch in the center of
the module and remove the insert holding the fuses. The insert contains two
fuses, the system fuse and a spare. Remove both fuses, then pull the two-prong
fuse holder out of the latching insert. Rotate the fuse holder and replace it into the
latching insert such that the proper line voltage is visible in the window. The
reading will be either 110 or 220. Place the proper fuse into the metal clips (1/4
amp SB for 110V operation and 1/8 amp SB for 220V operation), place the spare
fuse into the spare fuse area and replace the latching insert back into the power
module. Make sure the latch snaps are closed. Replace the power cord with the
