3.1.7. INPUTS
HID inputs are composed of three elements:
•
Stabilizing resistor
•
MOV
•
Contact from latching relay
Inputs vary depending on the HID model chosen. Thus, if the model corresponds to a type 1 application in the model
selection list, HID will have one single input; two for a type 2 application and three for a type 3 application.
HIDs can be supplied with or without latching relay.
If the unit includes a latching relay, then MOVs and resistors are dimensioned according to the HLB tripping time,
whereas if the unit does not include a latching relay, resistor and varistors are able to support a tripping time of
250ms.
