SECTION 2
EDR-PURE-IOM-230608
Electrical Connections and Devices
The boiler is designed to operate within the following limits at the connection
terminals:
ƒ
AC power supplied is within +/- 5% of the boiler rated voltage with the
rated frequency applied; or AC power supplied is within +/- 5% of the rated
frequency and with the rated voltage; or a combined variation in voltage
and frequency of +/-5% (sum of absolute values) of rated values.
Full Load Amps (FLA) is the measured amperage for the boiler at its maximum
operating condition at rated voltage. The type of breaker/fusing selected, in
combination with the FLA, will a ect proper circuit sizing/protection. Please refer
to your state's adoption of NEC or the authority having jurisdiction for proper
sizing/selection.
A connection box is provided on the back of the unit for high voltage wiring. A
separate connection box is provided for low voltage and communication wiring.
Do not run Building Management System (BMS) or any other communication
wiring into the high voltage box.
The Endura cabinet has removable panels to facilitate access. Do not run conduit
through or over access panels.
Adhere to the following when making electrical connections:
1. Install wiring in accordance with NEC Sec. 110.3(B) or CSA C22.1 for Canada
for a maximum recommended branch circuit voltage drop of 3% and a
maximum total voltage drop for a combination of both branch circuit and
feeder not to exceed 5%.
2. Install wiring and ground in boiler in accordance with authority having
jurisdiction or in absence of such requirements National Electrical Code,
ANSI/NFPA 70.
3. Connect power to the boiler using connectors rated for the minimum in
Table 1, and are compliant with local electrical codes.
4. Provide separate power supplies for external devices. Do not power
external devices (example: isolation valves, draft systems) through the
boiler.
