Electrical and Environmental Requirements
Mains Disconnect
A mains disconnect - providing over-current and short circuit protection - must
be provided. It disconnects the mains circuits from the mains supply. It may be a
switch disconnect or a circuit breaker. The DPT Rack and Safety Enclosure front
panel switch is only a standby switch and is not a LINE switch (disconnecting
device). The disconnect must:
Convenience outlets should be installed near the system for external equipment
such as computers and monitors, etc. Locate the outlets within one meter (three
feet) of the rear of the system.
Optional Safety Ground Connection
This DPT Rack and Safety Enclosure must be grounded properly for proper
operation and safety. Because the rack is connected to the AC mains by a
plug/socket connection, Keysight recommends a redundant permanent earth
ground connection to reduce the risk of electric shock.
Keysight Double-Pulse Test System Installation Guide
– Open all line conductors and neutral conductors where local code applies,
but do not open the protective earth conductor.
– Be marked "System Mains Disconnect" or the equivalent in your language.
– Be marked with a "|" for the "On" position or a "O" for "Off."
– Be capable of being locked in the "Off" position but not in the "On"
position.
– Be installed within three meters of the DPT Rack, where it can be easily
reached by the system operator without requiring the system to be moved
to access the disconnect.
A Safety Ground wire is not supplied with the DPT Rack and Safety
Enclosure and must be installed by a qualified electrician familiar
with local electrical codes.
