WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or
serious injury. All field wiring MUST be
performed by qualified personnel. Improperly
installed and grounded field wiring poses
FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow
requirements for field wiring installation and
grounding as described in NEC and your
local/state electrical codes.
General Recommendations
WARNING
Hazardous Service Procedures!
Failure to follow all precautions in this
manual and on the tags, stickers, and labels
could result in death or serious injury.
Technicians, in order to protect themselves
from potential electrical, mechanical, and
chemical hazards, MUST follow precautions
in this manual and on the tags, stickers, and
labels, as well as the following instructions:
Unless specified otherwise, disconnect all
electrical power including remote disconnect
and discharge all energy storing devices
such as capacitors before servicing. Follow
proper lockout/tagout procedures to ensure
the
power cannot be inadvertently
energized. When necessary to work with live
electrical components, have a qualified
licensed electrician or other individual who
has been trained in handling live electrical
components perform these tasks.
CAUTION
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as unit terminals are not
designed to accept other types of conductors.
The wiring procedures, as described in this portion
of the manual, must be accomplished to obtain
proper operation of the unit.
All wiring must comply with National Electrical
Code (NEC) and state and local requirements.
Outside the United States, the national and/or local
electrical requirements of other countries shall
apply. The installer must provide properly sized
system interconnecting and power supply wiring
with appropriate fused disconnect switches. Type
and locations of disconnects must comply with all
applicable codes.
Minimum circuit ampacity, recommended fuse
sizes and other unit electrical data are provided in
the Electrical Data table and on the unit
nameplate.
Checking the Power Supply
Electrical power to the unit must meet stringent
requirements for the unit to operate properly. Total
voltage supply and voltage imbalance between
phases should be within the tolerances listed in this
manual.
