2. Resistor leads should be cut to a length of
approximately 1 1/2 inches (40 mm).
3. Bend the leads and install the resistors as
shown in Figure 6.
4. Maintain a 3/8 inch (10 mm) minimum gap
between the resistor body and the terminal
block or any other neighboring parts.
NOTE
The resistors can only be used within the
flameproof (Ex d) terminal compartment.
Unused conduit entries shall be closed with
suitable blanking elements.
