Caution
This controller is intended to control equipment under normal operating
conditions. Failure or malfunction of the controller may lead to abnormal
operating conditions, which result in personal injury or damage to the equipment
or other property. Devices (limit or safety controls) or systems (alarm or
supervisory) intended to warn of or protect against failure or malfunction of the
controller must be incorporated into and maintained as part of the control system.
Installing the rubber gasket supplied will protect the controller front panel from
dust and water splash (IP54 rating). Additional protection is needed for higher
IP rating.
This controller carries a 90-day warranty. This warranty is limited to the
controller only.
