Maintenance - Eaton Cutler-Hammer BIHI Instructions Manual

A TRIPPED CONDITION IS A RESULT OF A
FAULTED POWER CIRCUIT CONNECTED TO THE
EQUIPMENT. FAILURE TO CORRECT SUCH
FAULTED CONDITIONS CAN CAUSE SEVERE
EQUIPMENT OR CABLE DAMAGE, PRESENT
A POTENTIAL FIRE HAZARD AND RESULT IN
DEATH OR PERSONAL INJURY.
IDENTIFY AND CORRECT FAULTED CIRCUIT
BEFORE ATTEMPTING TO RESET TRIPPED
SWITCHES WITHIN THE ATSBI EQUIPMENT.
TO RESET BYPASS SWITCH
1. Move appropriate Bypass Switch operating
handle down to full "OFF" position. This reset
action may require more downward force than
used to open the switch only. A correctly reset
switch will allow the operating handle to remain
in the full "OFF" position. If the operating handle
remains in a "Midway" position after inital reset
attempt, the switch is not reset. Try again.
2. The lit "Bypass Tripped" amber light should turn
off.
3. Move appropriate Bypass Switch operating
handle up to the "ON" position.
4. Verify that the appropriate "Bypass Energized"
red light is lit.
NOTE: An Automatic opening of any Moulded
case Switch used in the ATSBI equipment will
only occur if that specific switch is closed in the
power circuit on which a fault occurs. Therefore,
it is only necessary to reset affected switches as
indicated by the lit pilot lights.
OPTIONAL OVERCURRENT PROTECTION AND
SERVICE EQUIPMENT (OPTION 16 AND 17)
(OPTION 37)
Effective July 2007
CAUTION
12
The Cutler-Hammer ATSBI equipment can be
optionally (16 and 17) equipped with integral
overcurrent (overload and short circuit) protection. If
selected the standard Moulded Case Switches with
instantaneous short circuit releases are replaced
with conventional circuit breakers equipped with
thermal elements in addition to magnetic releases to
provide overload and short circuit protection to
connected equipment and cables. These circuit
breakers will replace the standard Moulded Case
Switches in the ATS and Bypass Switches only. The
Isolation Switch will only employ Moulded Case
Switches.
Units optionally supplied as service equipment rated
(Option 37) will inlcude this integral overcurrent
protection as standard. The service equipment rated
unit will also have provisions for service disconnect
as required by the NEC. A service disconnect
position is a built in feature of the service equipment
rated Cutler-Hammer ATSBI Switch.
STORAGE
If the ATSBI is to be stored prior to installation it
should be ordered with packaging/crating suitable
for the storage environment both mechanically and
environmentally. The equipment is not designed or
packaged for outdoor storage and warranty will be
withdrawn upon evidence of extended outdoor
exposure. It is strongly suggested that this
equipment be stored in a climate controlled
environment with temperature ranges between -20º
C to 85º C with a relative humidity of 80%
condensation or less.

MAINTENANCE

The ATSBI is maintenance free under normal usage.
Local conditions, however, may make it necessary to
clean the equipment once a year. De-energize all
sources of power and vacuum away any dust, dirt,
or debris that may have accumulated within the
enclosure or on logic components.
Follow recommendations of the Generator
manufacturer as to testing procedures and
frequency of the associated standby set.
