Electrical Data Sheet And Definition - CARNES HBGH Installation, Operation And Maintenance Manual

ELECTRICAL CONNECTIONS
POWER MUST BE OFF BEFORE MAKING ANY ELECTRICAL
CONNECTIONS.
Check unit electrical characteristics on label outside of cabinet. It
must agree with power provided to the unit. If it does not, contact
your Carnes Representative.
A fused disconnect or circuit breaker not provided by Carnes,
MUST be installed per local and national codes. See Table 4 for
recommended circuit ratings. The optional circuit breaker switch,
offered as an accessory, installed in the humidifier, is NOT for use
as a replacement for the required external disconnect switch, but
as a maintenance convenience addition.
1. Remove screws securing hinged panel for access to wiring.
See Photos D, E and F for different electrical locations.
2. An opening is provided on the bottom of the electrical
section. Bring electrical power lines through this opening and
connect to electric power terminals.
3. Connect cabinet ground terminals to an independent ground.
DO NOT use the neutral of a four-wire power supply.
4. Replace electrical cover panel.

ELECTRICAL DATA SHEET DEFINITIONS
1. Optional Circuit Breaker column designates the presence,
quantity and amp rating of optional circuit breakers (except
for select models over 48 amps). In addition, as an option,
internally mounted, switchable on-off, circuit breakers are
available in models with an 'HB' prefix.
2. Maximum Lb./Hr. designates maximum capacity of the
humidifier. Units are shipped from the factory preset at the
maximum rate. The output rate may be easily reset after
installation anywhere between 100% and 25% of maximum
capacity.
3. Voltage and Phase designate available phase and nominal
voltages. Single phase units may be operated from two legs
of a three phase supply but the load will be unbalanced.
4. kW is the power rating of the maximum output rate of the
humidifier. If a unit's max output is adjusted lower, the kW is
reduced proportionally.
5. Line Amp and Disc. Size are amp ratings shown for use in
selecting electrical service requirements.
6. Steam Cylinder shows the quantity and model of steam
generating cylinders mounted inside the humidifier. Each
cylinder requires its own steam distribution pipe, steam hose
and condensate return line.
7. Cylinder Wire Current is the current a single cylinder wire
should be carrying for a given unit at max output. This does
not include 'dummy' electrode wires that never carry any
current, i.e. humidifiers with C65 cylinders and single phase
humidifiers not using AX cylinders.
