ENGLISH
Refer to individual circuit breaker instruction manuals shipped with the switchboard
for additional maintenance information, such as changing rating plugs, sensor
plugs, or adjustable settings and removing circuit breakers. If the instruction
manual is not available, refer to “Section 11—Reference Publications” on page 54
for the appropriate number, or contact your local Schneider Electric representative.
3. A full function test kit, catalog number FFTK, is available from Schneider Electric
to test PowerPact M,
P, and R circuit breakers equipped with Micrologic trip units.
It runs trip unit tests automatically, with prompts to the user for initial information.
Test modules for each circuit breaker frame are used to store data necessary for
automatic tests. Series B Micrologic trip units require test module CBTMB, which
is included in UTS3.
A pocket tester, catalog number S434206, or UTA tester, catalog number
STRV00910, are available from Schneider Electric to test PowerPact H, J, and L
circuit breakers with Micrologic trip units. These testers supply power to the
Micrologic trip units and allow for settings to be adjusted through the keypad
located on the circuit breaker or through a PC using the USB interface.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• If adjusting circuit breaker settings, do not set the long-time trip rating at a
higher ampacity than the rating of the bus bar or load cables it supplies;
overheating can occur.
• Before energizing the switchboard, fill all unused I-Line circuit breaker
mounting spaces with blank fillers and/or extensions as listed in Table 3.
Failure to follow these instructions will result in death or serious injury.

NOTICE
HAZARD OF PLUG-ON CONNECTOR DAMAGE
• Do not remove the protective lubricant on the plug-on connectors.
• If additional lubrication is required, apply a coating of electrical joint compound,
catalog number PJC7201, to the contact surfaces of the plug-on connector.
Failure to follow these instructions can result in equipment damage.
