5.1 ELECTRICAL CONNECTIONS
A complete electrical wiring diagram for the Modulex is provided under separate cover in the manual
package. For electrical ratings, refer to the technical data in paragraph 1.5. The boiler installation
requires a 120 VAC, 60 Hz – single-phase power input. The electrical connections must conform to
local and NEC or CEC requirements. Utilization of adapters, multiple sockets or extensions cords are
not permitted. It is imperative that these safety requirements be adhered to. If in doubt, request an
accurate assessment of your electric system by highly qualified personnel.
AERCO is not liable for any damage caused by connection to an improper grounding system. The gas
and water feeding pipes and the central heating system pipes cannot be used as grounding means.
Boiler electric safety is guaranteed only when it is properly connected to an effective grounding system,
which is in compliance with the regulations in force.
The use of any electrically powered equipment implies the observance of some fundamental rules, such
as:
•
Do not touch the boiler with any wet part of your body and/or barefooted; do not pull the
supply cable.
•
Do not expose the boiler to sunlight, rain, etc.
•
Keep the boiler away from untrained people.
WARNING
The boiler’s electrical supplying cable must not be replaced by the user. In case of any
damage to the cable, stop the boiler and contact qualified personnel for its replacement.
IMPORTANT
Prior to connecting external AC power to the Modulex boiler, the CSD-1 Supply Manifold
must be installed using the procedures described Piping Manual GF-115-P-H.
1. External power at 120 VAC, 60 Hz, single phase is first connected to the Low Water Cutoff and
Aquastat provided on the CSD-1 Supply Manifold. Refer to Wiring Diagram 68004 provided in
the manual package for connections to the CSD-1 Manifold.
2. Following connection of 120 VAC power to the CSD-1 Manifold, the power leads are routed to
the Junction Box shown in Figure 5-1. The Junction Box is accessed by removing the front
panel from the boiler.
3. Route the wires from the CSD-1 Manifold through the cutout labeled 120V on the Left side of
the boiler. If necessary, the cutout labeled 24V is used for low voltage signals such as external
sensors.
4. The boiler’s Junction Box contains a polarized terminal block. Therefore, the Red (Line - L1) and
White (Neutral - L2) wires from the CSD-1 Manifold MUST BE connected to terminals L1 and
L2 respectively on the terminal block in the Junction Box. The output cable from the Junction
Box is terminated with a 3-pole plug, which connects to the boiler’s electrical components. If
incorrectly wired, the boiler goes into a “lockout” condition.
