Voltage And Circuit Protection; Extension Cords - DeWalt D55170 Instruction Manual

1. The cord set and plug (N) with this unit
contains a grounding pin (O). This plug
MUST be used with a grounded outlet
(P).
IMPORTANT: The outlet being used must
be installed and grounded in accordance
with all local codes and ordinances.
2. Ensure the outlet being used has the
same configuration as the grounded
plug. DO NOT USE AN ADAPTER.
3. Inspect the plug and cord before each
use. Do not use if there are signs of
damage.
4. If these grounding instructions are
not completely understood, or if in doubt as to whether the
compressor is properly grounded, have the installation checked
by a qualified electrician.
DANGER: Risk of electrical shock. IMPROPER GROUNDING
CAN RESULT IN ELECTRICAL SHOCK.
• Do not modify the plug provided. If it does not fit the available
outlet, a correct outlet should be installed by a qualified electri-
cian.
• Repairs to the cord set or plug MUST be made by a qualified
electrician.

Extension Cords

Using extension cords is not recommended. The use of extension
cords will cause voltage to drop resulting in power loss to the motor
and overheating.
Instead of using an extension cord, increase the working reach of
the air hose by attaching another length of hose to its end. Attach
additional lengths of hose as needed.
115V If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade grounding plug, and
N
a 3-slot receptacle that will accept the plug on the product
P
• in good condition
• no longer than 50 feet (15.2 m)
• 12 gauge (AWG) or larger. (Wire size increases as gauge num-
O
ber decreases. 10 AWG and 8 AWG may also be used. DO NOT
230V
USE 14 OR 16 AWG.)

Voltage and Circuit Protection

N
Refer to Voltage and Minimum Branch Circuit Requirements
under Motor Specifications.
CAUTION: Certain air compressors can be operated on a
O
15 amp circuit if the following conditions are met.
• Voltage supply to circuit must comply with the National Electrical
Code.
• Circuit is not used to supply any other electrical needs.
• Extension cords comply with specifications.
• Circuit is equipped with a sufficient size circuit breaker or time
delay fuse for the motor set up, see Motor Specifications. NOTE:
If compressor is connected to a circuit protected by fuses, use
only time delay fuses. Time delay fuses should be marked "D" in
Canada and "T" in the US.
If any of the above conditions cannot be met, or if operation of the
compressor repeatedly causes interruption of the power, it may be
necessary to operate it from a circuit capable of providing a larger
amount of current, see Motor Specifications. It is not necessary to
change the cord set.
