Electrical Connections and Devices

The boiler is designed to operate within the following limits at the connection
terminals:
AC power supplied is within +/- 10% of the motor rated voltage with the
ƒ
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 +/-10% (sum of absolute values) of rated values provided
the frequency variation does not exceed +/-5% of rated frequency.
There is no warranty on components that fail due to improper electrical
ƒ
service.
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 affect 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 has been provided on the back of the unit for high voltage
wiring. A conduit knock-out has been provided on the top of the unit for low
volatage 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 and ground in boiler in accordance with authority having
jurisdiction or in absence of such requirements National Electrical Code,
ANSI/NFPA 70.
