T_335, T_591 Errors

Hi all,

This is our first time to purchase electric forklifts and it has been 2years using them. The errors in the unit are T_335 and T_591. May I ask your suggestions on what to check? I only have these error description:

T_335 - 335 - With main contactor activated, capacitor voltage at power module 1A1 too low.

Where is module 1A1?

Hope to receive your replies.

Thank you.
