Section 8: Making the Necessary Connections
Checking the Electrical Supply
Important Information
Caution
Check the polarity of the AC power supply using a DIGITAL VOLTMETER TL-1445. Applying power of non-
standard polarity will void the warranty and can cause damage to the PROCESSOR.
Important
Contact your local power authority to determine whether the typical daily voltage at your site is within the range of
104 to 127 V AC. If the power authority states that the power available is within the range of 104 to 127 V AC, the
site does not require the use of a TRANSFORMER KIT. If the voltage at your site is not within the range, the
TRANSFORMER KIT CAT No. 167-4340 is required.
Important
Contact your local power authority to determine whether the typical daily voltage at your site is within the range of
207 to 253 V AC. If the power authority states that the power available is within the range of 207 to 253 V AC, the
site does not require the use of a TRANSFORMER KIT. If the voltage at your site is not within the range, the
TRANSFORMER KIT CAT No. 171-0292 is required.
