Page 6: Installation
5. INSTALLATION DANGER! Make sure the AC power supply is disconnected and protected against acciden- tal energization before starting the installation; Check the motor direction of rotation, turning it without load before it is coupled to the load; To prevent accidents, ensure that the grounding connection has been performed according to the applicable standards and that the shaft key has been securely fastened before the motor is started;... - Page 7 Only remove the corrosion protection grease from the shaft end and flange immediately before the motor installation. Unless specified otherwise in the purchase order, WEG motors are dynamically balanced with “half key” and without load (uncoupled). The driving elements, such as pulleys, couplings, etc., must be balanced with “half key” before they are mounted on the shaft of the motors.
- Page 8 The motor must always be positioned so the drain hole is at the lowest position; Slinger: WECM / Emerald product in vertical shaft up mounting should be fitted with water slinger ring to prevent water ingress inside the motor. Consult WEG about this optional. ATTENTION! Motors installed outdoors or in the vertical position require the use of additional shelter to protect them from water.

Item 6.6 - PASSIVE POWER FACTOR CORRECTION (PFC) (OPTIONAL). WEG declares that the WECM / Emerald eZA motor line is intended to be used as a part of an end-product and thus is not an independently used machine. All cables of this product need to be internally installed into the enclosure of the final product. - Page 10 Occasional different behavior during the normal operation (actuation of thermal protections, noise level, vibration level, temperature and current increase) must always be assessed by qualified personnel. In case of doubt, turn off the motor immediately and contact the nearest WEG service center.

- Page 12 Figure 6 - Product standard control switches NOTE! The standard maximum speed value is preset at WEG to be the highest value of the speed range but, can be changed by the user (see item 6.3). The product has speed memory when operating in local speed adjustment. The last speed adjusted will be kept in memory when the input power supply is removed.
