Read this page before any work is performed on elevator equipment. The pro-
cedures contained in this manual are intended for the use of qualified elevator
personnel. In the interest of your personal safety and the safety of others, do
not attempt any procedure that you are not qualified to perform.
All procedures must be accomplished in accordance with the applicable rules in the
latest edition of the National Electrical Code, the latest edition of ASME A17.1, and
any governing local codes.
CAUTION statements identify conditions that may result in damage to the
equipment or other property if improper procedures are followed.
WARNING statements identify conditions that may result in personal injury if
improper procedures are followed.
Before applying power to the controller, check that all manufacturing wire con-
nections are tight on relays, contactors, fuse blocks, resistors, and terminals on
cards and DIN rail terminals. Connections loosened during shipment may
cause damage or intermittent operation.
Other specific warnings and cautions are found where applicable and do not appear in this
Elevator Employee Safety and Accident Prevention Program Manual
summary. See the
and the Elevator Industry Field Employees' Safety Handbook
safety information on installation and service.
All wiring must be in accordance with the National Electrical Code and be consistent with
all state and local codes.
To avoid fire hazards, use only a fuse of the correct type, voltage, and current rating. See
the job specific drawings sheet (Power Supplies) for fusing information.
Electric shocks can cause personal injury or loss of life. Circuit breakers, switches, and
fuses may not disconnect all power to the equipment. Always refer to the wiring diagrams.
Whether the AC supply is grounded or not, high voltage will be present at many points.
Printed circuit boards may be damaged if removed or installed in the circuit while applying
power. Before installation and/or removing printed circuit boards, secure all power. Always
store and ship printed circuit cards in separate static bags.
Unless otherwise directed, always Turn OFF, Lockout, and Tagout the mainline disconnect
to remove power from elevator equipment. Before proceeding, confirm that the equipment
is de-energized with a volt meter. Refer to the
Prevention Program Manual
Elevator Employees' Safety and Accident
for the required procedure.
