The surge modules must be selected for use with the appropriate bases. The MTL4-
SDR must be used with the MTL4-BSISR or MTL4-BSGPR as these have one pin
connection blanked off to prevent the MTL4-SD module from being inserted

Link LK1 is fitted in IS applications when a suitably certified field device requires an increased
power level from the IS interface. Typically used with solenoid valves and maybe 4-20mA
transmitters, this link reduces the safety resistor to a lower ohmic value.
LK1 is positioned in the top of the MTL4-BSIS. Lift tag holder out of the way, as shown, and insert
the link into the 2 socket holes provided. The link is visible to the user when installed.
