Location

When choosing a location for installing the Honeywell M7284Q 1098/B servomotors, it is recommended to provide sufficient space to accommodate the necessary accessories and ensure the convenience of engine maintenance. In the case of outdoor installation, it is necessary to use moisture-proof connectors and a junction box with protection from external conditions conforming to the NEMA 3 standard.

For outdoor installation in any position, except vertical, it is recommended to use the 4074ERU environmental protection kit together with moisture-proof connectors corresponding to the NEMA 3 protection class. This will provide reliable protection against external influences, such as moisture and dust, and improve the overall performance and durability of installed servomotors.
