General 

 

Connection notes 

 

 

DANGER 

DEATH OR SERIOUS PHYSICAL INJURY WHEN THE COVER OF THE CONTROL 
UNIT APEX IS OPENED IN AN EXPLOSIVE ATMOSPHERE. 

Risk of explosion. 

 

Before opening the lid of the enclosure, check the atmosphere for 
any explosive gases. 

 

ATTENTION 

SHORT-CIRCUITS DUE TO LOOSE OR PROTRUDING WIRES IN THE CONTROL 
UNIT APEX. 

The control unit APEX may be damaged. 

 

All core wires, including those not required, must be attached to a 
terminal. 

 

Lay the wires only in the space between the shield bus and the 
connecting terminal. 

 

Make sure that none of the wires are loose or jump out/protrude. 

AVOID DAMAGE TO THE SEAL. 

Cancellation of the Ex protection concept. 

 

Visual inspection of the seal when closing the control unit APEX 
(cleanliness, seat and integrity). 

AVOID RAPID DISCONNECTION AND RECONNECTION OF THE POWER 
SUPPLY. 

Internal protection circuits can trip 

 

Wait approx. 30 seconds between switching off and switching on 
again. 

 

 

Recommendation for the securing of active parts 

The Ex e terminals should be protected against contact by a 
protective cover.  

 

The procedure for connecting cables to the Ex p control unit is described in the 
following: 

Procedure: 

 

Establish the electrical connections in accordance with the terminal 
assignment. Terminals are designed in tension spring technology. A 
suitable tool must be used for this purpose.
