Making Electrical Connections

Run 24V Class II wiring only through specified low

voltage opening. Run line voltage wiring only through

specified high voltage opening. Do not combine voltage

in one opening.

USE COPPER CONDUCTORS ONLY.

This unit is provided with knock-outs for conduit. Refer to

Figure 11 for unit wiring diagram, which includes all field

wiring. Separate openings have been provided for 24V low

voltage and line voltage. Refer to the dimension illustration

on Page 2 or Page 3 for specific location.

Wiring must conform to the current National Electric Code

ANSI/NFPA No. 70, or Canadian Electric Code Part I,

CSA Standard C22.1, and local building codes. Refer to

following wiring diagrams. See unit nameplate for minimum

circuit ampacity and maximum overcurrent protection size.

Select the proper supply circuit conductors in accordance

with tables 310-16 and 310-17 in the National Electric

Code, ANSI/NFPA No. 70 or tables 1 through 4 in the

Canadian Electric Code, Part I, CSA Standard C22.1.

The motor speed is set by the speed tap connection to the

low voltage terminal strip in the control section. The speed

can be increased by swapping wires as shown in Figure

11.

Less than 100' (30m)

More than 100' (30m)

Table 6. Run Length (Class II Rated Wiring)

Install room thermostat (ordered separately) on an inside wall

approximately in the center of the conditioned area and 5 feet (1.5m)

from the floor. It should not be installed on an outside wall or where it

can be affected by sunlight or drafts.
