Handling Instructions of VIP Relays
The handling instructions for the VIP installed on the Ringmaster AirSeT are as follows:
-
Handling: Handle the equipment with appropriate care, check the VIP condition by visual inspection and energizing.
-
Transport: VIP relays can be transported by all suitable means of transport in the usual conditions for unit.
Storage conditions should be taken into consideration for a long period of transport. -
Storage: It is recommended to keep the VIP in its original packaging for as long as possible to help protect the unit during storage.
VIP relays, like all electronic devices, should not be stored in humid or damp conditions for more than one month. The relay should be powered up as soon as possible after installation to maintain optimal performance. If immediate energization is not possible, the unit reheating system must be activated to help prevent moisture-related damage.
