Do not branch in parallel current which exceeds the rated current. If branched in
parallel, current imbalance or other problems may develop. If it is absolutely
necessary to branch such a large current in parallel, be sure to use contacts
made of phosphor bronze. Design the circuits without causing imbalance and
provide an extra margin for each circuit.

Note: 1. Models identified as VHR-( ) M incorporate measures to prevent
electric shock and are thus safer in regard to high voltages.
2. The applicable housing for 2 circuits shrouded header is "VHR-2N"
only. "VHRR-2N" is not applicable.
3. Contact JST for Glow Wire compliant connectors.
