Introduction
HE4000 Encoding System
2.0.2 Powering On The HE4000
The rear panel AC power supply interface includes a fuse holder, and an IEC 320 power cord
receptacle. The typical HE4000 configuration requires 70 Watts.
An auto-sensing, auto-ranging AC switching power supply powers the HE4000 unit. The supply
accepts 90 to 132 VAC and 180 to 240 VAC nominal input voltage levels cycling at 50 to 60 Hz.
A 1 Amp fuse on the rear panel protects the power supply from excessive current.
The On/Off (1/0) power switch is located on the front panel.
2.0.3 AC Power Cords
The HE4000 shipping kit includes two AC power cords, one for North American applications,
specifically the United States and Canada, and the other for international applications.
AC wiring must be done in accordance with governmental standards and
codes in effect at the HE4000 installation site.
Refer to the Safety
Precautions for additional information.
2.0.4 North American Applications
One cord has an IEC- compatible female plug on one end and a North American male plug on the
other. This cord is UL and CSA approved up to 125 VAC at 10 A. This cord is ready to use with
no user wiring required.
2.0.5 International Applications
The international 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 by many international safety agencies,
including VDE, up to 250 VAC at 6 A.
2.0.6 Connecting to a Power Source
To connect to an AC power source, follow these steps:
1.
Select an AC power cord. If an international power cord is selected, attach a
connector in accordance with local regulations and laws.
2.
Ensure the HE4000 power switch is in the Off, or 0 position.
3.
Connect the female plug of the AC power cord to the AC power receptacle on the
HE4000 rear panel.
4.
Connect the male plug of the AC power cord to an external AC power
conditioning surge suppressor.
5.
Connect the AC power conditioning surge suppressor to an AC outlet.
