Remote Meter Panel
All meter wires are to be twisted pairs or twisted shielded wi
re grounded at one
point only. Use 16 or 18 ga. wire 600V insulation.
Control potentiometer(s) must be twisted wires or twisted shie
lded cable grounded
at one point only.
Use 16 or 18 ga. wire, 600V insulation.
All wires for meter panel lights, switches, meters, and contro
l potentiometers must
be run in its own separate conduit.
Output
All output Hf cables should be inter-posed to reduce impedance
and power losses.
All output Hf cables should be run in non-ferrous non-magnetic
conduit or tray
to prevent induction heating of conduit or tray.
(CONT.)
General
No additional timers, relays, or lights are to be connected to
the inductron's
control transformer.
No additional timers, relays, or lights are to be mounted in t
he inductron cabinet
or meter panel without prior approval by the Tocco R & D
department.
Maximum altitude 6,000 ft. Notify Tocco R & D if requirements
exceed this
value.
TWO (2) PORTABLE WORK STATIONS, OL-68 SERIES
The OL-68 Work Station is a steel enclosure designed to house and cool the e
lectrical components
which convey high frequency power to an inductor. The construction of the c
abinet permits
mounting in any position.
