1. The electrical supply cables must be suitable for the power rating
(see the certificates delivered with the IMVS2000v2, if available, or the
IMVS2000v2 nameplate);
2. Gather the necessary tools for the assembly and setting of the IMVS2000v2 controls;
3. Check that the coupling dimensions of the actuator flange and stem meet the
IMVS2000v2 coupling dimensions;
4. Clean the actuator flange and remove anything that might prevent a perfect
adherence to the IMVS2000v2 flange and especially all traces of grease.
If a long storage period has occurred, before installing the IMVS2000v2, please:
1. Check the status of the O-ring seals;
2. Check the installation of the plugs or cable glands on the cable entries;
3. Check whether the enclosure covers of the IMVS2000v2 body are cracked or broken.
