ELECTRICAL CONNECTION

Equipment is available in various electrical configurations. All customer
connections can be made at the terminal connections located in the
customer electrical connection box on the rear of the dryer. (Refer to
General Arrangement and appropriate Wiring Diagrams.)
A suitable fused disconnect switch or circuit breaker, in accordance with
national and local code requirements, is recommended for all Ingersoll
Rand equipment. Refer to the Engineering Specifications Section for
voltage requirements and load.
A
CAUTION
Never wire directly or connect any additional wires to the compressor
junction box. This will cause severe system malfunction.
8.4.1 Ingersoll Rand dryers can be configured for three variations of
start modes: Manual Mode, Automatic Mode and Remote
Mode. Refer to Section 10 for instructions on how to change
the dryer's start settings. The instructions below describe the
methods to configure the dryer for a particular Start Mode.
A) Manual Mode (Factory Default) - No modification required
to operate dryer in Manual Mode. Once power is applied,
dryer can be started or stopped by depressing the local
ON / OFF pushbuttons located on the front panel.
B) Auto Restart Mode - Auto Restart Mode permits the dryer
to start after a brief delay once power is applied to the
dryer. Note that the dryer's touch pad will still affect dryer
operation. Depressing the OFF button will de-energize the
refrigeration compressor
components. After the OFF button has been depressed,
the user must depress the ON button to permit the dryer to
operate.
