Step 4 Ð Make Electrical Connections

POWER SUPPLY Ð Electrical characteristics of available power supply must agree with unit nameplate rating. Supply voltage must be within the limits shown in Tables 10A or 10B, 11 and 12. See Table 13 for control circuit data and Table 14 for fan motor electrical data.

IMPORTANT: Operation of unit on improper supply voltage or with excessive phase imbalance constitutes abuse and can affect any Carrier warranty.

FIELD POWER CONNECTIONS Ð All power wiring must comply with applicable local and national codes. Install ®eld- supplied, branch circuit safety disconnect(s) of a type that can be locked off/open. Disconnects must be located within sight of, and readily accessible from, the unit in compliance with NEC (National Electrical Code) (U.S.A. Standard) Article 440-14.

All ®eld power enters the unit through a hole in the con- trol box shelf. Refer to Fig. 20-28 for ®eld wiring details.

MAIN POWER Ð Units 38AH044-104 have single-point power connection to simplify ®eld-power wiring (all power enters at one end). Units 38AH124 and 134 require 2 con- nection points, one for each module. Units may use copper, copper-clad aluminum, or aluminum conductors at all volt- ages. The maximum wire size units can accept per terminal block is 500 kcmil.

Power must be supplied as shown in Table 15.

CONTROL CIRCUIT WIRING Ð Control circuit wiring is accomplished with a step-down transformer on voltage des- ignations 500, 600, and 100 in table below where the pri- mary voltage is ®eld voltage. For 208/230-v, 3-ph, 60-Hz units, ensure that the transformer primary is wired properly for the voltage which will be applied. All control wiring must comply with applicable local and national codes. The safety circuits are 24 v on all units. The safety circuit voltage is created with a step-down transformer where main control voltage is the transformer primary voltage.

See Table 13 for control circuit information.
