1. INTRODUCTION
This manual contains installation, operation and maintenance instructions for the T51P and T51XW Indicators. Please read this
manual completely before installation and operation.
1.1 Safety Precautions
• Verify that the input voltage range printed on the data label matches the local AC power to be used.
• Make sure that the power cord does not pose a potential obstacle or tripping hazard.
• Use only approved accessories and peripherals.
• Operate the equipment only under ambient conditions specified in these instructions.
• Disconnect the equipment from the power supply when cleaning.
• Do not operate the equipment in hazardous or unstable environments.
• Do not immerse the equipment in water or other liquids.
• Service should only be performed by authorized personnel.
• The T51XW is supplied with a grounded power cable. Use only with a compatible grounded power outlet.
For safe and dependable operation of this equipment, please comply with the following safety precautions:
1.1.1 Relay Option Safety Precautions
This equipment may have an optional AC or DC Relay Option board installed. This option allows external devices to be
controlled by the Indicator.
CAUTION: ELECTRICAL SHOCK HAZARD. REMOVE ALL POWER CONNECTIONS TO THE INDICATOR
BEFORE SERVICING OR MAKING INTERNAL CONNECTIONS. THE HOUSING SHOULD ONLY BE OPENED BY
AUTHORIZED AND QUALIFIED PERSONNEL, SUCH AS AN ELECTRICAL TECHNICIAN.
Before making connections to the Relay terminals, remove power from the system. If the system contains an optional
rechargeable battery system, be sure that the ON/ZERO Off button is used to fully turn off the system after removing the AC power
plug.
More detailed installation instructions are included with the Relay Option Kit when purchased.
