WARNING
This procedure involves a risk of electric shock that could cause property damage,
injury and/or death.
All electrical connections should be performed only by properly trained and
certified electricians wearing proper protective gear and using properly insulated
tools.
Before attempting to make any electrical connections or disconnections to the
chiller:
•
Verify that the chiller’s main disconnect handle is in the OFF posi tion
•
Verify that the incoming power to the chiller has been turned off
•
Lock out and tag out main electrical connecting points
•
Use a voltmeter to verify there is no incoming power to the chiller
Ensure that the supply power is enough to meet the chiller electrical requirements as found on the unit’s data
tag. The data tag is found on the front of the electrical enclosure. If a remote display is provided with the unit,
install the provided 150-foot communications cable between the chiller electrical panel and the remote display
location. For distances over 150 feet, an optional Long Distance Remote Display kit is required.
Connect power as follows:
1. Open the electrical enclosure by turning the main disconnect handle to the OFF position and releasing
the quarter-turn latches using a flathead screwdriver.
2. Use a step bit or knockout punch to install appropriate conduit fittings in the electrical enclosure.
WARNING
Take care to prevent any metal chips from falling on the electrical components in
the enclosure while installing conduit fittings. Metal chips can cause shorts in
electrical components and introduce arc flash hazards.
3. Wire mains power to the main disconnect. Wire the ground lead to the provided ground lug.
4. Close the electrical enclosure and fasten the quarter-turn latches.
