Installation
Receiving Instructions
The VS-I is carefully packed at the factory to protect it from damage during shipping; however, careless
handling during shipment can result in damage. If any damage to the VS-I is discovered, immediately
notify both the shipping agent and Woodward.
Unpacking Instructions
Carefully unpack the VS-I and remove it from the shipping container. Do not remove the hydraulic,
electric blanking covers and hydraulic power cylinder’s output threaded shaft mesh until you are ready to
mount the unit.
The external ground lugs shown on the installation drawing must be
properly connected to ensure equipotential bonding. This will reduce
the risk of electrostatic discharge in an explosive atmosphere.
External fire protection is not provided in the scope of this product. It
is the responsibility of the user to satisfy any applicable requirements
for their system.
Take care not to damage the electronics cover’s seal, the cover
surface, the threads, or the VS-I housing mating surface while
removing or replacing the cover.
For Division 1/Zone 1 products: Proper torque on all joints is very
important to ensure that the unit is sealed properly.
For lifting and transportation, use lifting straps fitted through both
lifting lugs provided with the product. Support the VS-I in a vertical
position during transportation.
Due to typical noise levels in engine and turbine environments, hearing
protection should be worn when working on or around the VS-I.
The surface of this product can become hot enough or cold enough to
be a hazard. Use protective gear for product handling in these
circumstances. Temperature ratings are included in the specification
section of this manual.
