ATTENTION: Wear a wrist-type grounding strap
when servicing 1336 IMPACT drives. Failure to
protect drive components against ESD may damage
drive components. Refer to Electrostatic Discharge
Precautions at the beginning of this chapter.
Important: Before you remove connections and wires from the
drive components, mark the connections and wires to
correspond with their component connections and
terminals to prevent incorrect wiring during assembly.
1. Remove power from the drive.
2. Check for zero volts at TB1 terminals +DC and –DC.
3. Check for absence of control voltage at:
• TB10
• TB11
• L Option Board (if used)
4. Remove the Snubber Board from the drive. Refer to
Chapter 3 – Disassembly and Access Procedures, Removing the
