Instruction Manual: evolution 5000 E57xx DSNG and DENG Voyager Encoder
ST.TM.E10076.3
The unit has a Technical earth terminal (marked with ) located at the
rear panel. Its use is recommended. This is NOT a Protective earth for
electric shock protection. The terminal is provided to:
1. Ensure all equipment chassis fixed within a rack are at the same
Technical earth potential. To do this, connect a wire between the
Technical earth terminal and a suitable point on the rack.
2. Eliminate the migration of stray charges when connecting between
equipment.
WARNING...
IF THE TERMINAL SCREW HAS TO BE REPLACED, USE THE FOLLOWING:
1U ENCODER - M4 X 10 mm LONG POZIDRIV PANHEAD.
2U ENCODER - M5 X 12mm LONG POZIDRIV PANHEAD.
USING A LONGER SCREW MAY CAUSE A SAFETY HAZARD.

WARNINGS...
1. DO NOT OVERLOAD WALL OUTLETS AND EXTENSION CORDS AS THIS CAN RESULT IN A
RISK OF FIRE OR ELECTRIC SHOCK.
2. AS NO MAINS SWITCH IS FITTED TO THIS UNIT, ENSURE THE LOCAL AC POWER SUPPLY IS
SWITCHED OFF BEFORE CONNECTING THE SUPPLY CORD.
3. THE ENCODER IS NOT FITTED WITH AN ON/OFF SWITCH. ENSURE THAT THE SOCKET-
OUTLET IS INSTALLED NEAR THE EQUIPMENT SO THAT IT IS EASILY ACCESSIBLE.
FAILURE TO ISOLATE THE EQUIPMENT PROPERLY MAY CAUSE A SAFETY HAZARD.

EXTERNAL MEANS OF DISCONNECTION. FAILURE TO ISOLATE THE EQUIPMENT PROPERLY
MAY CAUSE A SAFETY HAZARD.
CAUTIONS...
1. This product should be operated only from the type of power source indicated on the marking label.
If you are not sure of the type of power supply where the Encoder is to be mounted, consult a
qualified electrical engineer for the vehicle, the vehicle manufacturer or their agents.
2. The Encoder can be connected to a positive or negative earth system but you must ensure that
correct polarity to the DC input connections are maintained.
