Opening the enclosure may expose live electrical circuits. Touching exposed terminals or wires may cause
death or serious injury. Always turn off and isolate the system before opening the door. Do not switch back on
4.1 How to Open and Close the Enclosure
1) Ensure that it is safe to open the enclosure and, if necessary switch off and isolate electrical power.
2) Unscrew the two 3mm Hex socket security screws (1) until they become loose (2).
3) With a gloved hand only, pull the handle until it comes free (3). Do not apply undue force.
4) Open the enclosure door fully.
5) Closure is the reverse of this procedure, but care must be taken not to exert undue force, and do not
press on the membrane or touch screen areas.
Note: The door recess has an environmental seal that requires some pressure to close the door correctly.
The enclosure handle is the primary method of applying this pressure but you can assist it by pressing on the
door edge directly above the handle as you press on the handle itself.
until the door is reclosed and secured. Do not operate TPPLW with the door insecure.
Take alternative site safety precautions while power is off.
