J8: This jumper selects the optional encoder supply voltage. When J8 is closed
between pins No. 1 and 2, the encoder supply is 16Vdc; when closed between pins
No. 2 and 3, the encoder supply is 5Vdc.
J2: This is a two pin jumper. When closed the safety contact is internally grounded.
When open the safety contact is floating and should be externally polarized (see
8.1).
