III. Installation
Electrical Wiring
The MegaTron XS series digital glycol feeder controller has an internal regulated power supply that will
operate in the range of approximately 90 to 250 VAC at 47 to 63 Hz on the incoming wiring. Output relay(s)
are protected with a replaceable fuse. Each relay’s output voltage will equal incoming line voltage. The
Standard prewired units are supplied with a 8 foot, 16 AWG, 3 wire grounded, 120 VAC USA power cord for
incoming power.
NOTE: Liquid tight fittings and labeled signal lead cables are provided for all signal (low voltage)
connections, low drum level and pressure transducer.
WARNINGS:
1. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Wiring must be done
according to all applicable local codes.
2. Power (line voltage) must be disconnected while making any connections. If power is
supplied to the unit, line voltage will be present on the relay cards.
3. Low voltage signal wires (transducer, level, alarm, etc.) should never be run in conduit
with high voltage wires.
Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and a clear view of the controller.
The location should be convenient to grounded electrical connections and system plumbing connections.
Mount the glycol feeder stand to a level concrete pad using the ½” mounting holes in the base of the stand.
Concrete pad construction and anchoring bolts must comply with local building codes. The required sample
line plumbing should be connected to the return header of the Hydronic system
WARNING:
Avoid locations that expose the controller to direct sunlight, vapors, vibration,
liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C).
EMI(electromagnetic interference) from radio transmissions and electric motors can also
cause damage or interference and should be avoided.
