E-Compact Medium Power
1. Introduction.
This section provides information on the minimum installation requirements for E-Compact
Series transmitters with recommendations on shelter, tower, antennas, cables, grounding,
mains, transient preventions, etc.
2. Minimum Requirements.
2.1. AC Mains - Wire Gauge.
Consumption with the equipment running at its maximum power.
Current (A) on each wire:
About AC MAINS TYPE, see Section 8 – Attachments, USA AC Mains Types for E-
Compact Series.
The current quoted in the table is more loaded phase to sizing effect of conductors and
protection.
Said gauge is the minimum recommended for the transmitter in question, if the cable
length is large, consider voltage drop in the cable maximum of 5%
The section of the neutral conductor should be the same as the phase.
The section of the ground conductor has to be the same as the conductors phase.
2.2. Grounding.
The grounding system to which the Hitachi Kokusai Linear TV transmitter will be attached
must be designed and implemented by a qualified professional. An improper grounding
system may jeopardize the equipment as well as the lives-of the professionals working in
the shelter. To be considered proper, the grounding must have a resistance of no more than
5 Ohms.
