HE4000 Encoding System
Preface
Provide Adequate Ventilation
Slots and openings on the HE4000 are provided for ventilation that is needed to ensure reliable
operation. To avoid overheating and ensure that the ventilation slots are not blocked, place the
HE4000 on a smooth, hard surface that has at least two inches of clearance around the unit and
adequate air circulation. If the equipment is placed in a closed area, such as a rack, ensure that
proper ventilation is provided and that the internal rack operating temperature does not exceed
the maximum rated temperature at the position of the HE4000.
Never place the HE4000 on a soft surface that would obstruct the required airflow into the
ventilation slots.
Use the Correct Power Source
For units equipped with a North American power cord, the cord has an IEC-compatible female
plug on one end, and a male plug on the other end. This cord is UL and CSA approved up to 125
VAC at 10 A and is ready to use with no user wiring required.
For units equipped with an International power cord, the cord has an IEC-compatible female plug
on one end, and three stripped and tinned bare wires on the other end. This cord is approved up
to 250 VAC at 6 A and complies with the international color codes of green/yellow (ground), blue
(neutral), and brown (line).
If these color codes do not correspond to the colored markings on the terminals in the plug, use
the following standards:
The green/yellow wire must be connected to the plug terminal marked by the letter E or
by the “earth” symbol
, or color-coded green and yellow.
The blue wire must be connected to the plug terminal marked with the letter N or color-
coded black.
The brown wire must be connected to the plug terminal marked with the letter L or color-
coded red.
An AC plug must be attached to the International power cord in accordance with government
standards and codes in effect at the installation site. If an unterminated power cord is supplied
with the unit, the appropriate certified termination plug must be installed. The following is a list of
