MOUNTING ON A MICRO PANEL
Risk of Electric Shock. Disconnect or
isolate all power supplies before making
electrical connections. More than one
disconnect or isolation may be required to
completely de-energize equipment. Con-
tact with components carrying hazardous
voltage can cause electric shock and may
result in severe personal injury or death.
IMPORTANT: When attaching the SC-EQ Enclosure
to a Micro Panel, ensure the SC-EQ Enclosure does not
impede access to other components.
To mount the SC-EQ Enclosure on a Micro Panel:
1. Disconnect power to the chiller Micro Panel.
2. Make sure the SC-EQ Enclosure ts properly
and that no obstructions, such as internal boards,
switches, or external conduit, prevent mounting
or servicing of the panel. See Figure 23 on page
21 for examples of good mounting locations.
3. Locate and remove the two plastic caps in the bot-
tom of the SC-EQ Enclosure.
4. Mark an appropriate place on the enclosure for a
matching set of knock out holes. Mark and drill,
or punch, two holes in the Micro Panel.Using two
bulkhead pipe couplers, attach the SC-EQ Enclo-
sure to the Micro Panel.
5. Complete wiring as described in the Applying
Power section in this document.
IMPORTANT: Be careful not to damage the SC-EQ
or Micro Panel’s circuit boards during the installation.
Protect all circuit boards from metal chips, which may
cause short circuits if left on the boards at startup.
Use of bulkhead pipe couplers provides
sufcient clearance to allow removal of
the SC-EQ Encloser cover.
