5.To stop unit (Emergency Stop) with contacts other than those shown, install the stop contact between 5 and 1. If a stop device is not installed, a jumper must be connected between terminals 5 and 1. De- vice must have a minimum contact rating of 100VA at 115 volts A.C.
6.Alarm contacts are for annunciating alarm/unit mal- function. Contacts are rated at 115V, 100VA, resis- tive load only, and must be suppressed at load by user.
7.See Installation, Operation and Maintenance Manual when optional equipment is used.
8.Control panel to be securely connected to earth ground.
