Tester and electrical connectors for insulated glass units

A system comprising:

• a window assembly including an electrochromic device;
• an electrical connector including a connection interface configured to couple with a connector of the window, the connection interface comprising a first plurality of pins and/or sockets configured to transfer information and/or power between the window assembly and a controller coupled with the connection interface wherein
• the controller configured to apply, through the connection interface, a voltage profile to the electrochromic device based at least on a received input, and/or configured to receive data from the window:
• and
• a cap configured to mate with the connection interface by way of a plurality contacts;
• wherein
• one or more of the plurality of contacts are configured to allow charge to drain from the electrochromic device by shorting two or more of the pins and/or sockets together when the cap is mated with the connection interface.

A method comprising:

• preparing an optically switchable window for installation, wherein the optically switchable window includes:
• (i) an electrochromic device, (ii) an electrical connector including a connection interface, the connection interface comprising a plurality of pins and/or sockets and (iii) a cap configured to mate with the connection interface by way of a plurality of contacts, the preparing including:
• electrically shorting at least two of the plurality of pins and/or sockets such that charge is drained from the electrochromic device by attaching a cap configured to mate with the connection interface by way of a plurality contacts, one or more of the plurality of contacts being configured to short two or more of the pins and/or sockets together;
• and
• electrically decoupling the at least two of the plurality of pins and/or sockets, after charge has been substantially drained from the electrochromic device.
